ABOUT THE LIBRARY
The LUMCON Library collection was originally housed in Ellender Memorial Library, located at Nicholls State University in Thibodaux, Louisiana. After completion of the DeFelice Marine Center in 1986, the collection was moved to its present location. Since that time, the Library has become an active resource center for LUMCON faculty and staff as well as Consortium member institutions, visiting researchers, students, and the public.
The library contains a computer lab and several study spaces available to visiting students, scientists, or groups (such as attendees of a writing retreat).
The collection and development of library materials reflects LUMCON’s research programs. The collection has approximately:
- 4,600 monographs
- 5,800 bound volumes
- 200 journal titles
- 26 current journal subscriptions
- 850 maps
- 35 atlases
- 3,600 government documents
- 1,500 reprints
In addition, the library houses a complete collection of research products generated by DeFelice Marine Center personnel since LUMCON’s inception.
HOURS OF OPERATION
- The LUMCON Library is staffed Monday through Friday from 7:00 AM to 3:30 PM. All visitors are welcome during these hours.
- The Library is closed to the public on weekends, state holidays, and when the librarian is not on site. Before visiting the facility, please call 985-851-2875 to ensure the Library will be open.
- All LUMCON staff, summer students, and resident visitors have 24-hour access to the Library. If the doors to the Library are locked, the security guard will open them for you.
CIRCULATION
- Books can be checked out by filling out a card at the circulation desk. The length of time a book can be checked out varies depending on the patron’s status. Books may be renewed by contacting the department, but all items are subject to recall at any time.
- Interlibrary loan service is available for LUMCON faculty, postdocs, lab personnel, and summer students. Although we strive to get items at no charge, the patron may be asked to pay for interlibrary loan charges under certain circumstances.
- Reserve items, reference materials, and journals must remain in the Library. The Library has no photocopier, but copies or scans can be made in the LUMCON main office.
- All materials must be checked out before removal from the Library, without exception.
- Library materials can be placed on reserve for summer classes. A list of items to be placed on reserve should be provided to the librarian as soon as possible.
- When returning material that has been checked out, please drop off items at the circulation counter.
Food is not allowed in the Library under any circumstance. Drinks are only allowed with prior approval by the librarian or the security guard.
INTERNSHIP PROGRAM
The LUMCON Library is available as an internship site for graduate-level students who have completed at least two semesters toward a Master’s degree in Library and Information Science. Applications will be accepted on a continuing basis and internships may be completed during any semester. Prior library experience or an undergraduate degree in science is desirable, but not necessary. Credits will be awarded based on the number of person-hours completed (40 person-hours per credit hour).
The internship will consist of both field experience, encompassing many operations of a special library, and a special project in technical services. The Librarian will give the intern an overview of reference services, technical services, library administration, and budgeting, and will guide the intern through special projects. The LUMCON Library uses SIRSI/Dynix’s Symphony Integrated Library System as well as OCLC for Cataloging/Interlibrary Loan services.
Contact the Librarian for more information or to apply for an internship.

Abstract
The contamination of sea otter (Enhydra lutris) fur with crude oil or dispersants reduces its insulation and could subject the animal to hypothermia. This study tested methods for removing crude oil from sea otter pelts, and measured changes in insulation caused by oil contamination and subsequent cleaning. Four detergents and two pretreatments were tested on sea otter pelts soiled with fresh crude, 5-day weathered crude, and an oil–dispersant (COREXIT 9527) solution. To examine the effects of oiling and cleaning on the thermal properties of the fur, the thermal conductance of untreated, oiled, and cleaned pelt samples was determined with a heat-flow transducer. Changes in lipid concentration in the fur resulting from contamination and cleaning were also assessed. The results demonstrated that Dawn dishwashing detergent was the most effective agent in removing crude oil from sea otter fur. This detergent removed similar amounts of oil with 15 or 40 °C rinse water, and was less effective when used in conjunction with mineral oil or soap pretreatments. Oil contamination caused a two- to four-fold increase in thermal conductance over base-line levels (7.64 ± 1.30 W/(m2∙ °C)). Following cleaning, the thermal conductance of the pelt was not significantly different from that of untreated fur. However, mean lipid weight decreased from 7.4 mg lipid/g fur in untreated pelts to 2.0 mg lipid/g fur in cleaned pelts. This study demonstrated that even though natural oils may be lost during the cleaning process, proper cleaning and rinsing restores the water repellency of the sea otter pelt after exposure to crude oil

Abstract
The ‘detergent’ BP 1002 at concentrations of 1 ppm was detected immediately by the larvae of Sabellaria spinulosa which were intensely irritated by it. In loosely covered vessels, allowing the solvent fraction to evaporate, larvae seemed at first to recover but died several weeks later, the control larvae remaining active and normal. The surfactant and stablilizer fractions at concentrations of 2.5 ppm killed the larvae within a day or two

Abstract
Any decision to treat or not to treat an oil spill with dispersants involves a multiplicity of biological, chemical, physical, and meteorological inputs. Knowledge concerning the fate of treated and untreated spills is a prerequisite for estimating environmental impacts. Biological data concerning acute toxicity levels and the interrelationship of the affected marine biota must be understood and quantified, as well as the weathering of the oil, the modification of it by microorganisms, and the change in the chemical and physical nature of the oil spill by various types of dispersants. Most of the information required to conduct such an assessment is not presently available and must be obtained by a series of laboratory, meso-scale and in situ types of experiments. The type of information obtained from each type of experiment is discussed and the role it plays in the assessment process is presented

Abstract
Fish species consisting of haddock, herring, sole, lemon sole, pilchard and plaice were used to establish acute toxicities of several oil dispersants. The type and aromatic content of the solvent were found to be the main factors influencing toxicity. Much lower toxicities were noted for “second generation” dispersants. Aging of dispersant solutions resulted in decreased toxicities, perhaps related to a loss of aromatic compounds from each solution. Salinity and temperature had minimal influence on toxicity. Dispersant exposure demonstrated that species types showed smaller differences in susceptibility than age differences within species. A similar susceptibility for larvae of all species was noted at the newly-hatched stage, with susceptibility growing throughout the yolk-sac stage. The most critical stage was the transition period from yolk reserves to an external food supply. Dispersants seemed to act primarily as physical toxins, initially causing a reversible narcosis. Implications are discussed in relation to the use of dispersants at sea

Abstract
The effects of BP1002, Finasol ESK and Corexit 7664 on the development of herring, Clupea harengus L., plaice, Pleuronectes platessa L. and sole, Solea solea (L.) were examined. Abnormalities in cell division and differentiation, reductions in heart rate, eye pigmentation, growth rate and hatching success were seen in developing embryos when exposed to BP1002 and Finasol ESK at concentrations above 10 parts/106 for 100 hours. Exposure to 5 parts/106 resulted in larvae with abnormal flexures of the spine, preventing them from feeding successfully. Exposure to dispersants at lower concentrations during embryonic development, from fertilization to hatching (15 to 20 days) stages, produced similar abnormalities. Corexit 7664 produced no demonstrable harmful effects on embryos when exposed to concentrations up to 5000 parts/106

Abstract
Factors affecting the toxicity of various oil-dispersing agents, as sprayed on sea water, were studied using embryos and larvae of 6 species of marine fish; some results are given in graphs and tables. The relative toxicities of the compounds, the same for all species tested, depended mainly on the type and aromatic content of the solvent; evaporation and/or degradation was a major factor affecting the toxicity; temperature and salinity had little effect. Differences in sensitivity between species were less than those between different stages of the same species; on hatching there was a dramatic reduction in the 100 hour LC50 value from more than 20 p.p.m. to less than 8 p.p.m Although embryos were more tolerant than larvae in acute toxicity tests, they showed growth abnormalities and delays in development when exposed to sub-lethal concentrations. Sub-lethal concentrations also affected the behaviour pattern of the larvae and impaired their ability to capture prey, but they recovered on return to clean water

Abstract
The responses of larvae to horizontal and vertical gradients of oil dispersant in sea water have been studied. Horizontal gradients were established in a 5-channel fluvarium in which the concentrations of dispersant increased in a stepwise manner across the test yard. In each run, the positions of 10 larvae were noted every 30 sec for 30 min and their mean positional values (mpvs) calculated for each 2 min interval. No marked avoidance reactions were noticed even at 30 parts/106, the highest concentration tested. However, the mpv tended to clean water values with all concentration gradients. This tendency was also time-dependent. These changes in distribution resulted from increased activity of the larvae in the dispersant and not from a chemo-taxis. Vertical gradients were established by carefully layering the dispersant onto sea water. Larvae did not avoid any of the concentrations tested (1-100 parts/106) but remained in the dispersant layer until they became narcotized. These inactive animals sank into clean water where they recovered and swam upward again into the toxic layer. This pattern endured over 48 hours. It is concluded that fish larvae are unable to detect the dispersants at these concentrations and would not avoid areas of dispersants at sea. However, because of the effect of dispersants larvae would sink or swim from lethal concentrations

Abstract
The paper describes some of the factors to be considered in establishing a standard technique of toxicity testing for ranking oil dispersants. Methods of measuring pollutant toxicity to fish are presented, time/mortality curved for the brown shrimp, Crangon crangon being given, together with statistical techniques for measuring their reliability. The significance of constraints necessarily imposed in tests such as these is discussed. Toxicity response curves of several dispersants tested under the same conditions are compared. The tests were maintained for some considerable time one consequence of this being that the effective concentration of a dispersant is correspondingly lower. Median lethal concentrations estimated from these tests were used for defining the toxicity of the dispersants; while this method may be suitable for offshore spp as a result of low concentrations resulting from the extensive dilution of the dispersant in the sea, it is not recommended for estimating the toxicity to littoral spp, where exposure to very high concentrations of dispersants is probable; suitability of tests must be assessed in relation to field conditions. Rank order for ten dispersants, obtained from toxicity tests using several test spp is given

Abstract
This paper represents a review of European approaches to the purpose and problems of testing the toxicity of hydrocarbons and dispersants. It was prepared by the authors following a meeting of a group of European ecologists, which was convened by the Dispersant Working Group of the UK Institute of Petroleum Co-ordinating Committee for the Prevention of Sea Pollution. The paper deals with the aims of toxicity tests, and draws distinctions between those devised for toxicity ranking purposes, required by governments and industry for assessing the potential of new products, and those tests done for predicting possible ecological effects from the spillage of oil or use of dispersants. The paper also discusses the principles guiding the two approaches, and compares the use of LD50 with tests examining recovery and survival. Laboratory tests are examined in relation to field experiments and experience. In discussing laboratory practice, chemical problems, standardisation, the selection of test organisms, sampling, experimental design data processing and data presentation are considered

Abstract
Comparative studies were done to determine the influence of a dispersant on the bioavailability of naphthalene from crude oil to the unicellular golden-brown algae, Isochrysis galbana, under changing temperature and salinity conditions. Conditions were selected to represent a range (two temperatures, 12 and 20°C, and two salinities, 22 and 34‰) encountered in Pacific waters, where extensive crude oil transport and refining occurs. Cells were exposed to laboratory preparations of either the water-accommodated fraction (WAF) of Prudhoe Bay crude oil (PBCO) or a dispersed oil (DO) mixture of PBCO and Corexit 9527® spiked with [U-14C]naphthalene. Uptake increased by as much as 50% in DO, 20°C exposures run at 22‰ (0.24 7mol naphthalene/g algae in WAF, 0.37 7mol naphthalene/g algae in DO) compared with comparable exposures at 34‰ (0.23 7mol naphthalene/g algae in WAF, 0.37 7mol naphthalene/g algae in DO). A 24-h bioaccumulation factor (BAF) calculated in the absence of steady state indicated increasing bioaccumulation with decreasing temperature. No significant variation in relative metabolite composition occurred under the different experimental conditions. Results of these experiments showed that the use of dispersants enhanced the uptake of naphthalene by microalgae under a variety of temperature and salinity conditions, independent of aqueous concentration

Abstract
Use of chemical dispersants as oil spill clean-up agents, alters normal behavior of petroleum hydrocarbons (PH) by increasing functional water solubility. The bioavailable fraction may be increased through higher PH concentrations in the water column and altered interactions between dispersant, oil, and biological membranes. The objective of this research was to determine the impact of dispersing agents on PH bioavailability and trophic transfer. Uptake, bioaccumulation, depuration, and metabolic transformation of a model PH, [14C]naphthalene, were measured and compared for Prudhoe Bay crude oil (PBCO) dispersed with Corexit® 9527 (DO) and undispersed preparations of the water-accommodated fraction (WAF) of PBCO. The model food chain consisted of Isochrysis galbana, a primary producer, and Brachionus plicatilis, a primary consumer. Direct aqueous (AQ) exposure was compared with combined aqueous and dietary (AQ and D) exposure. Results showed uptake of naphthalene by rotifers was not increased significantly (P>0.05) in the presence of dispersant. A significant (P

The golden-brown algae Isochrysis galbana, a primary producer, was used to determine the influence of the chemical dispersing agent, Corexit 9527®, on the bioavailability of naphthalene. Cells were exposed to laboratory preparations of either the water-accommodated fraction (WAF) of Prudhoe Bay crude oil (PBCO) or a dispersed oil (DO) mixture of PBCO and Corexit 9527 spiked with [U-14C]naphthalene. Uptake was determined by the amount of algae-associated [14C]. High-pressure liquid chromatography (HPLC) co-chromatography was used to fractionate and identify metabolic products. A 24-h bioaccumulation factor (BAF) was calculated in the absence of steady state. The presence of Corexit 9527, had significant influence (p = 0.001) on the uptake of naphthalene, but no significant effect on the 24-h BAF (BAF: 168 and 180 from WAF and DO, respectively), or metabolic fate of naphthalene in I. galbana. Results of this research indicate that dispersants have the potential to increase organismal exposure to certain petroleum hydrocarbons without increasing their aqueous concentration

Abstract
Use of chemical dispersants as oil spill clean-up agents alters normal behavior of petroleum hydrocarbons (PH) by increasing functional water solubility. Different PHs may respond differently to dispersant based on their individual physical properties and altering the composition of the bioaccessible fraction of the oil. The objective of this research was to determine the impact of dispersing agents on the bioavailability and trophic transfer of phenanthrene, a model for a class of compounds in oil characterized by limited water solubility and the potential to bioaccumulate. Uptake, bioaccumulation, and depuration of [14C]phenanthrene, were compared for Prudhoe Bay crude oil (PBCO) dispersed with Corexit® 9527 (dispersed oil or DO) and undispersed preparations of the water-accommodated fraction (WAF) of PBCO. The model food chain consisted of Isochrysis galbana, a primary producer, and Brachionus plicatilis, a primary consumer. Direct aqueous (AQ) exposure was compared with combined aqueous and dietary (AQ&D) exposure.

Abstract
Adaptation to sublethal exposure to crude oil by phytoplankton is poorly understood. Use of chemical dispersants for oil spill remediation increases petroleum hydrocarbon concentrations in water, while exposing marine organisms to potentially toxic concentrations of dispersant. Heat shock proteins (hsps) have been found to serve as an adaptive and protective mechanism against environmental stresses. The objective of this project was to examine the induction of hsps in Isochrysis galbana, a golden-brown algae, following exposure to the water-accommodated fraction (WAF) of Prudhoe Bay crude oil (PBCO) and PBCO chemically dispersed with Corexit 9527® (dispersed oil: DO). Initial experiments using 35S-labeled amino acids and 2-dimensional electrophoresis with subsequent western blotting identified and confirmed hsp60, a member of the chaperonin family of stress proteins, as being efficiently induced by heat shock in this species. One-dimensional SDS PAGE and western blotting, with hsp60 antibodies and chemiluminesence detection, were used to quantitate hsp60 following exposure to a range of environmental temperatures and concentrations of WAF and DO preparations.

Abstract
The objective of this research was to determine the impact of dispersing agents on petroleum hydrocarbon (PH) bioavailability and trophic transfer in primary levels of a marine food chain. Uptake, bioaccumulation, and metabolic transformation of a model PH, [14C]naphthalene, were measured and compared for Prudhoe Bay Crude Oil (PBCO) dispersed with Corexit® 9527 (DO) and undispersed preparations of the water-accommodated fraction (WAF) of PBCO. The model food chain consisted of Isochrysis galbana, a primary producer, and Brachionus plicatilis, a primary consumer. Fractionation and identification of metabolites was done by HPLC co-chromatography, and quantitation was done by liquid scintillation counting (LSC). Results show that uptake of naphthalene increases somewhat (P < 0.01) in the presence of dispersant in algae and a slight (P < 0.001) increase in uptake was observed in rotifers via trophic transfer

Abstract
Use of chemical dispersants as oil spill clean-up agents may alter the normal behavior of petroleum hydrocarbons (PH) by increasing their functional water solubility, resulting in increased bioavailability and altered interactions between dispersant, oil, and biological membranes. The objective of this research was to determine the impact of dispersing agents on PH bioavailability and trophic transfer to larval fish from primary levels of a marine food chain. Uptake, bioaccumulation, depuration, and metabolic transformation of a model PH, [14C]naphthalene, were measured and compared for Prudhoe Bay crude oil (PBCO) dispersed with Corexit 9527® (DO) and undispersed preparations of the water-accommodated fraction (WAF) of PBCO. The model food chain consisted of a primary producer, Isochrysis galbana; and a primary consumer, the rotifer, Brachionus plicatilis; and larval topsmelt, Atherinops affinis. Direct aqueous (AQ) exposure was compared with combined aqueous and dietary (AQ&D) exposure. Dispersants altered the uptake and depuration processes of naphthalene, independent of aqueous concentrations, in primary trophic species of a marine food chain. The amount of naphthalene taken up by topsmelt was initially significantly (P≤0.05) enhanced in the presence of dispersant, reaching a maximum more quickly than undispersed samples. Dispersion treatment significantly increased naphthalene dispension in topsmelt (P≤0.05) from both AQ and AQ&D exposures. No significant change in naphthalene uptake by fish was observed with the addition of contaminated food for either WAF or DO medium; however, both uptake and depuration rate constants varied significantly with route of exposure consistent with greater naphthalene turnover. The majority (≥72%) of naphthalene-derived radioactivity from fish tissue following all exposures was in the parent form, with smaller quantities of α- and β-naphthols, α- and β-naphthyl sulfates, and an unidentified derivative

Abstract
The fate of Prudhoe Bay crude oil labelled with n(1−14C)-hexadecane and dispersed with Corexit 9527, was studied for 24 days in a polyethylene bag enclosure of sea water by time-series observations of the alkane composition of the crude oil, oil fluorescence, 14C-labelled hexadecane in the particulate phase, bacterial biomass, amounts of sedimented material and parameters of temperature, salinity, particulate organic carbon and nitrogen, and nutrients. By the seventh day, convective and diffusive mixing, important mechanisms for the dispersion of oil, resulted in a fairly homogeneous distribution of oil throughout the enclosed water column. Rapid bacterial biodegradation removed the n-alkane fraction initially, while oil-Corexit dispersion suppressed phytoplankton growth. After 7 days, with the recovery of phytoplankton growth, much of the aged oil sedimented with sinking of diatoms

Abstract
Most toxicity tests are based on the continuous exposure of the bioassay organisms to a series of fixed concns of toxin, with virtually no attention being paid to the ability of the organisms to recover when removed to clean surroundings. Such methods make no allowance for fluctuations in concn of toxins which occur in the environment. An experiment using the stage II nauplius of the barnacle Elminius modestus was set up to demonstrate that toxicity as determined on the basis of simple ' knock-down' concns does not fully describe the biological impact of a chemical on an organism. The 30 min EC50's producing immobility were determined for various decyl surfactants. On this basis the relative toxicities of the surfactants were, in descending order, nonionic > anionic > cationic. The experiment was repeated but the nauplii were removed from the test solns after 30 mins, washed, and placed in aerated sterile sea water. Recovery was assessed on the ability of the nauplii to fully regain their swimming ability. By using recovery as an index of toxicity the order of relative toxicity of the surfactants was reversed i.e. cationic > anionic > nonionic. The author concludes that if recovery experiments were included as an integral part of aquatic bioassay techniques, then the mode of action of toxins may be more fully understood, leading to a better assessment of their impact on the environment

Abstract
Bioremediation of crude oil in salt marsh mesocosms growing Spartina alterniflora was investigated during winter and summer to determine the influence of nitrogen (N) and phosphorus (P) fertilization, flooding, and season. Fertilization with urea and ammonium (NH4+) applied at 75 or 150 kg N ha-1 with or without P did not significantly (p = 0.05) increase oil or hydrocarbon degradation in continuously flooded mesocosms over an 82 day period during winter (temperature range of 17 to 30 °C). Phosphorus applied at 40 kg P ha-1 significantly (p = 0.05) increased oil and hydrocarbon degradation. Nitrate (NO3-) added alone did not increase oil or hydrocarbon degradation, but when added with P, it significantly (p = 0.05) increased degradation above that for P alone. Up to 70% of applied oil and 75% of applied hydrocarbons were degraded in P supplemented treatments. Inipol, an oleophilic fertilizer containing N, P, and a dispersant, significantly increased oil and hydrocarbon degradation. During a 40 day summer experiment (temperature range of 27–42 °C), N and P fertilization did not increase oil or hydrocarbon degradation. For continuously flooded treatments, 72% of applied hydrocarbons were degraded while 51% were degraded in alternately flooded treatments. Mesocosms provided conditions suitable for quantitative recovery of oil and results indicated that N and P fertilization, flooding, and season interacted to influence oil bioremediation. Even under the most favorable conditions, more than 1 month was required for most of the oil to disappear

Abstract
18 marine species, representing fish, tunicate, urchins, starfish, barnacle, mantis shrimp, bivalves, and gastropods, were used to establish toxicities for Shell Herder and BP 1100X. A wide range of toxicity susceptibility was found for species within a single animal group, indicating the difficulty in using a “representative” species for tests. It is suggested that ecologically important species (“key species”) be used in toxicity tests, rather than species that are easy to obtain in the field and/or maintain in the laboratory

Abstract
A settlement inhibition assay using barnacle cyprid larvae, Balanus amphitrite, was developed with Cd2+ and phenol as standard reference toxicants. Mean percentage settlement of cyprid larvae showed a progressive reduction with increasing concentrations of Cd2+ and phenol. A significant reduction in settlement was found when cyprids were exposed to 0.1 mgL-1 Cd2+ or 10 mgL-1 phenol. The assay was used to assess the sublethal toxicity of three oil dispersants (Vecom B-1425 GL, Norchem OSD-570 and Corexit 9905) commonly used in Hong Kong waters. Results of this investigation show that the barnacle settlement inhibition assay can be incorporated into the battery of tests currently available for ecotoxicological assessment of marine contaminants

Abstract
The effects of two oil dispersants (Vecom B-1425 GL and Norchem OSD-570) mixed with diesel oil on the survival and behaviour of the stage II nauplii of the barnacle Balanus amphitrite were investigated. The 24 and 48-hour LC50 values for Vecom B-1425 GL:diesel mixture were 514 and 48 mg l-1 respectively, while respective values for Norchem OSD-570:diesel mixture were 505 and 71 mg l-1. Under sublethal concentrations, increased levels of the dispersant:diesel mixtures caused a reduction in phototactic responses. Balanus amphitritenauplii failed to exhibit phototactic responses when exposed to Vecom B-1425 GL:diesel mixtures of 400 mg l-1 and higher for 24 hours. A longer exposure time of 48 hours further reduced the Lowest Observable Effect Concentrations(LOECs) to 60 mg l-1. The LOECs for Norchem OSD-570:diesel mixtures under exposure periods of 24 and 48 hours were 400and 80 mgl-1 respectively. The curvilinear velocities (VCL) and straight-line velocities (VSL) of the stage II nauplii ranged from 0.7–1.1 and 0.2-0.4 mms-1 respectively. Increased concentrations of dispersant:diesel mixtures caused a significant change in the curvilinear and straight-line velocities. Both oil dispersants, dispersant:diesel mixtures of 20 to 40 mgl-1 caused significant increases in VCL, but no significant change in VSL. Dispersant:diesel mixtures of 100 mg l-1 and higher resulted in a reduction in VSL for both dispersants

Abstract
A flow-through laboratory procedure was used to simulate a major, short-term oil spill in a shallow subtidal benthic reef environment. For these experiments, Arabian Light crude was chemically dispersed with Corexit 9527 or BP100 WD at 1-20 ppm concentrations. The hermatypic coral Diploria strigosa was used to study survival and behavior during 6-24 h exposures and a recovery period of 4 weeks. Temporary, sublethal effects occurred in corals when exposed to the highest concentrations. After 24 hours, limited mesenterial filament extrusion, tissue contraction, tentacle retraction and localized tissue rupture were observed to the organisms exposed to 20 ppm concentrations of dispersed oil. Long-term viability was not thought to be a potential impact, since colony recovery showed normal behavior returning after 2 to 4 days after exposures

Abstract
Seven compounds with different lipophilicities and structures—1,3,5-trichlorobenzene, pentachlorobenzene, acenaphthylene, 1,4-dimethyl-2-(1-methylphenyl)benzene, 4-ethylbiphenyl, 4,4′-dibromobiphenyl, and 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane—were subjected to bioconcentration tests in carp at concentrations below the water solubilities of the compounds in the presence or absence of a dispersant (either an organic solvent or a surfactant). The bioconcentration factors (BCFs) of the compounds were on the order of 102–104. The BCF values remained in the range of 15–49% for all the compounds, whether or not a dispersant was present, i.e., the BCF values in the presence of an organic solvent or a surfactant at a concentration below the critical micelle concentration were not significantly smaller than the BCF values in the absence of the solvent or surfactant. This result indicates that the dispersants had no influence on the evaluation of the bioconcentration potential of these test substances

Yamada, M. et al. 2003. Study on the fate of petroleum-derived polycyclic aromatic hydrocarbons (PAHs) and the effect of chemical dispersant using an enclosed ecosystem, mesocosm. Marine Pollution Bulletin, 47 (1-6): 105-113. ISSN: 0025-326X. doi:10.1016/S0025-326X(03)00102-4.
Abstract
Polycyclic Aromatic Hydrocarbons (PAHs) are one of the components found in oil and are of interest because some are toxic. We studied the environmental fate of PAHs and the effects of chemical dispersants using experimental 500 l mesocosm tanks that mimic natural ecosystems. The tanks were filled with seawater spiked with the water-soluble fraction of heavy residual oil. Water samples and settling particles in the tanks were collected periodically and 38 PAH compounds were analyzed by gas chromatography-mass spectrometry (GC-MS). Low molecular weight (LMW) PAHs with less than three benzene rings disappeared rapidly, mostly within 2 days. On the other hand, high molecular weight (HMW) PAHs with more than four benzene rings remained in the water column for a longer time, up to 9 days. Also, significant portions (10–94%) of HMW PAHs settled to the bottom and were caught in the sediment trap. The addition of chemical dispersant accelerated dissolution and biodegradation of PAHs, especially HMW PAHs. The dispersant amplified the amounts of PAHs found in the water column. The amplification was the greater for the more hydrophobic PAHs, with an enrichment factor of up to six times. The increased PAHs resulting from dispersant use overwhelmed the normal degradation and, as a result, higher concentrations of PAHs were observed in water column throughout the experimental period. We conclude that the addition of the dispersant could increase the concentration of water column PAHs and thus increase the exposure and potential toxicity for organisms in the natural environment. By making more hydrocarbon material available to the water column, the application of dispersant reduced the settling of PAHs. For the tank with dispersant, only 6% of chrysene initially introduced was detected in the sediment trap whereas 70% was found in the trap in the tank without dispersant

Abstract
Microbial responses to the addition of oil with or without a chemical dispersant were examined in mesocosm and microcosm experiments by using denaturing gradient gel electrophoresis of bacterial ribosomal DNA and direct cell counting. When a water-soluble fraction of oil was added to seawater, increases in cell density were observed in the first 24 h, followed by a decrease in abundance and a change in bacterial species composition. After addition of an oil–dispersant mixture, increases in cell density and changes in community structure coincided, and the amount of bacteria remained high. These phenomena also occurred in response to addition of only dispersant. Our results suggest that the chemical dispersant may be used as a nutrient source by some bacterial groups and may directly or indirectly prevent the growth of other bacterial groups

Abstract
Growth and reproductive processes in synchronous cultures of the alga Scenedesmus armatus (isolated from Baltic phytoplankton) were followed in the presence of various concentrations of dispersant DP-105, oil, and mixtures of oil and dispersant. The inhibition of protoplast fission was the most prominent effect of oil. Nuclear division was inhibited to a lesser extent. With an increasing concentration of oil, dispersant, or a mixture of both, the inhibitory effects were expressed earlier. The presence of oil compounds did not effect the timing of DNA replication, but it did reduce the number of replication rounds in a concentration dependent manner. The inhibition of DNA synthesis was accompanied by slightly delayed cessation of RNA and protein synthesis. Starch synthesis was always inhibited to a lesser extent, and at a later time, than other macromolecular syntheses. Pigment synthesis continued almost to the end of the cell cycle. Thereafter, a rapid degradation of all pigments began and the cells became bleached. No inhibitory effect on reproductive processes was found if oil or dispersant were added to cultures transferred into darkness. Furthermore, recovery from inhibition of reproductive processes caused by oil in continuously illuminated cultures was observed in darkened cells. Chemically dispersed fuel oil was only slightly more toxic than mechanically dispersed fuel oil; an additive, rather than synergistic, effect of oil/dispersant mixture was found

Abstract
The tank vessel Puerto Rican broke into two sections on November 3, 1984, following explosions and fires which had begun three days earlier. Approximately 30,000 barrels of lube oil and lube oil additives were released 32 miles west-southwest of the Golden Gate Bridge, San Francisco, California. After careful consideration of the possible effects on the environment of the application of dispersants, the U.S. Coast Guard On-Scene Coordinator requested and received authorization from the Regional Response Team to use Corexit 9527 for chemically dispersing the spilled oil. This was the first authorized use of dispersants on a major oil spill in the United States

Abstract
Seven strains of oil degrading bacteria were observed to determine the influence of Finasol OSR-5 on bacterial growth. With the exception of one species, no bacterial growth was observed when Finasol was the only C-donator in the culture medium. Finasol/crude oil (1:10) presence resulted in no bacterial growth for four of the seven strains, though development was robust when crude oil alone was used. Of the three strains that showed growth, amount of growth was inhibited by Finasol, compared to growth in the presence of crude oil alone

Abstract
Investigators established criteria for saltwater bioassays of oil dispersants. Criteria were then used in tests of nauplii of brine shrimp to compare results of 48 hour TL50 values for six dispersants with results of tests using sodium dodecyl sulfate. Methodological factors and variations potentially affecting results are discussed
