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.

- 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
During the past four years, a research program to investigate the effect of oil and dispersant chemicals on a freshwater ecosystem has been carried out. Laboratory experiments were used to select a suitable dispersant for a field trial and to develop monitoring techniques which would be capable of detecting chronic and sublethal effects in selected species of the freshwater ecosystem. The field trial demonstrated that a spill of light oil covering 5 to 10% of the surface of a shallow freshwater lake had no long-term measurable effects and that the application of a dispersant ameliorated some short-term effects even in this low-energy system

Abstract
During the past 10 years, there have been many sea trials of dispersant chemicals for the purpose of demonstrating the effectiveness of specific products or elucidating the processes of oil dispersion into the water column. Unfortunately, most of these tests have proved inconclusive, leading many to believe that dispersant chemicals are only marginally effective. Wave basin tests have been carried out at the Esso Resources Canada Limited laboratory in Calgary, Canada, to measure dispersant effectiveness under closely controlled conditions. These tests show that dispersed oil plumes may be irregular and concentrated over small volumes, so that extensive plume sampling was required to obtain accurate dispersant effectiveness measurements. In large-scale sea trials, dispersants have been shown effective, but only where sufficient sampling of the water column was done to detect small concentrated dispersed oil plumes and where it was known that the dispersant was applied primarily to the thick floating oil

Abstract
The impacts of oil and dispersed oil on freshwater ecosystems were examined in a field experiment conducted as part of the Freshwater Oil Spill Research Program. In July 1985, 3 m3 of Normal Wells crude oil were spilled on each of two fen lakes. The slick on one lake was treated with the dispersant Corexit 9550. Corexit 9550 was effective in removing the oil from the water surface even though wave energy was very low. The oil or dispersed oil had little detectable short or long term impact on all water quality parameters measured, or on the microbial populations and activities in the water column and sediments of both lakes. Untreated oil caused more damage than the dispersed oil to floating aquatic plants and the shoreline vegetation, but new growth within the affected areas was observed one month after treatment. Seasonal regrowth of vegetation in all areas affected by the treatments appeared normal. Our results suggest that the best response to oil contamination in isolated fen lakes is no action at all. However, floating oil or oil washed ashore could pose a significant threat to indigenous wildlife or its habitats. Under these conditions, chemical dispersion may prove to be an effective alternative when conventional control and recovery measures are not feasible

Abstract
Corexit 9527 and its constituent parts (including Span 80, dioctyl sulfosuccinate (AOT)) were used in treatments to determine what effects they had on the oxidation of acetate and alkanes in crude oil by Acinetobacter calcoaceticus ATCC 31012. Alkane oxidation was inhibited by the presence of Corexit 9527. Span 80 was found to increase oil oxidation rates while AOT strongly reduced oxidation rates. A combination of Span 80 and AOT was found to increase oxidation rates, though not as much as Span 80 alone. Acetate uptake and oxidation by A. calcoaceticus was affected in separate ways: nonionic surfactants interacted with acetate uptake while the anionic surfactant interacted with the oxidation process

Abstract
A Rhodococcus sp. 094 bacterium was tested for its ability to oxidize alkanes in crude oil emulsified by nonionic chemical and biological surfactants. Oxidation rates were measured in a 3-h period by Warburg respirometry. 14CO2 recovery was measured from the [1-14C]hexadecane spiked crude oil. Response to emulsified oil depended on the physiological state of the bacteria (i.e., cells harvested in the exponential and stationary growth phases) were tested. Oxidation rates by cells in the exponential growth phase were negatively affected by surfactant amendment. Oxidation rates by cells in the stationary growth phase were in some cases stimulated by surfactants. The stimulatory effect depended on both the chemical structure and the physicochemical properties (i.e., hydrophilic–lipophilic balance (HLB)) of the surfactants. Surfactants with intermediate HLB values (8–12) gave the best results. Neither the biosurfactants nor the commercial oil-spill dispersants tested had any significant stimulatory effect

Abstract
Biological effects of non-ionic surfactants on alkane-oxidizing bacteria were studied by assessing their influence on the uptake of prefluorochrome fluoresceindiacetate (FDA) and its intracellular hydrolysis to fluorescein. Both decreasing and increasing rates of hydrolysis as a consequence of the presence of surfactants were observed. The surfactants influenced the uptake of FDA, but not its intracellular hydrolysis. The effects of the surfactants on the uptake rate depended strongly on the structure and physico-chemical properties of the surfactants. There was no qualitative or significant quantitative difference in surfactant susceptibility between induced (alkane grown) and non-induced bacteria (acetate grown), even though the induced cells possess greater cell surface hydrophobicity

Abstract
The effects of oil-spill removers ('detergents') on a population of Nucella lapillus was studied at Porthleven in South Cornwall, where heavy oil pollution occurred following the Torrey Canyon incident in March 1967. Nucella is one of the shore animals which are most resistant to ‘detergent’ treatment, but at Porthleven the species was wiped out in the harbour and the majority of animals were killed on the reef nearby. Growing animals which recovered from the effects of the 'detergent' (BP 1002) were later found to have developed growth disturbances in the shell. These effects on growth were studied in the field and in the laboratory and appear to be an indirect effect of 'detergent' resulting from its interference with the ability of the animal to feed and with the availability of food. Recolonization of the reef was more rapid than expected and depended largely on the survival of some very young animals in the sublittoral zone. Probably because most of the potential predators had been wiped out by the 'detergent’, these animals were able to invade the reef in large numbers late in 1967. In fact, 2 years after the ‘detergent’ treatment, there was some evidence that the reef may have become overpopulated with Nucella. In contrast, recolonization of the outer harbour, where the species was wiped out, was slow during the first 2 years and dependent on lateral movements of animals from the reef. It is concluded that if the ‘detergent’ treatment of the reef had been slightly heavier then the species would have been wiped out there as well and would have been slow to recover

Abstract
Three experimental oil spills of 200, 400, and 200 litres (l) were conducted in October, 1978, in a semiprotected coastal area on Canada's west coast. The surface slicks were restrained with a Bennett inshore oil boom. The spilled oil was chemically dispersed using Corexit 9527, applied as a 10-percent solution in sea water and sprayed from a boat. The dispersed oil was monitored fluorometrically for some hours. Surface and dispersed oil were sampled for chemical analysis. The highest recorded concentration of dispersed oil was 1 part per million (ppm). After a short time (30 minutes), concentrations around 0.05 ppm were normal, decreasing to background within 5 hours. The concentrations were low compared to those expected for complete dispersion which, as visual observation confirmed, was not achieved. The dispersed oil did not mix deeper into the water column with the passage of time, in contrast to predicted behaviour and in spite of the lack of a significant vertical density gradient in the sea water. This was attributed to the buoyancy of the dispersed oil droplets and the limited vertical turbulence in the coastal locale of the experiment. The integrated quantity of oil in the water column decreased more rapidly than either the mean oil concentration of the cloud or the maximum concentration indicating that some of the dispersed oil was rising back to the surface. The surfacing of dispersed oil was confirmed visually during the experiment. The mixing action of the spray boat and breaker boards apparently created large oil droplets that did not form a stable dispersion. Horizontal diffusion of the dispersed oil was initially more rapid than expected, but the rate of spreading did not increase with time as predicted. The results imply that the scale of diffusion was larger than the scale of turbulence which again can be attributed to the locale of the experiment

Abstract
Excitation–emission matrix spectroscopy (EEMS) was used to characterize the ultra violet fluorescence fingerprints of eight crude oils (with a 14,470-fold range of dynamic viscosity) in seawater. When the chemical dispersant Corexit 9500® was mixed with the oils prior to their dispersion in seawater, the fingerprints of each oil changed primarily as an increase in fluorescence over an emission band centered on 445 nm. In order to simplify the wealth of information available in the excitation–emission matrix spectra (EEMs), two ratios were calculated. A 66–90% decrease in the slope ratio was observed with the addition of Corexit. When the slope ratios were reduced in complexity to intensity ratios, similar trends were apparent. As a result either of the ratios could be used as a simple and rapid means of identifying and monitoring chemically dispersed oil in the open ocean

Abstract
This paper summarizes a multi-year research program to address the decanting of water from oil spill fluids recovered by skimmers. The first series of tests, with two weir-type skimmers at Ohmsett, was conducted to study the rate and amount of free water separation that can be expected in temporary storage containers. The goal of this study was to predict the best time to decant water back into the boomed area and optimize the available onsite storage space. The results indicated that “primary break” (the initial separation of the recovered liquids) occurred within a few minutes to one hour, depending on the physical characteristics of the oil. Rapidly decanting this free water layer may offer immediate increases of 200 to 300% in available temporary storage volume. Initial oil concentrations in the decanted water also depended on the physical properties of the oil; they ranged from 100 to 3000 mg/L. These declined by a factor of approximately 3 after one hour after settling, and by a factor of approximately 5 after one day. The second series of tests was undertaken to develop a more complete understanding of the use of emulsion breakers injected into an oil spill recovery system at both lab-scale (at SL Ross) and mid-scale (at Ohmsett). The experiments were designed to assess the injection/mixing/settling regimes required for optimum water-removal from a meso-stable water-in-oil emulsion with an oil spill demulsifier. The use of a demulsifier injected into a recovery system, combined with decanting, did substantially reduce the volume of water in temporary storage tanks and the water content of emulsions for disposal/recycling

The first series of tests, with two weir-type skimmers at Ohmsett, was conducted to study the rate and amount of free water separation that can be expected in temporary storage containers. The goal of this study was to predict the best time to decant water back into the boomed area and optimize the available onsite storage space. The results indicated that “primary break” (the initial separation of the recovered liquids) occurred within a few minutes to one hour, depending on the physical characteristics of the oil. Rapidly decanting this free water layer may offer immediate increases of 200 to 300% in available temporary storage volume. Initial oil concentrations in the decanted water also depended on the physical properties of the oil; they ranged from 100 to 3000 mg/L. These declined by a factor of approximately 3 after one hour after settling, and by a factor of approximately 5 after one day. The second series of tests was undertaken to develop a more complete understanding of the use of emulsion breakers injected into an oil spill recovery system at both lab-scale (at SL Ross) and mid-scale (at Ohmsett). The experiments were designed to assess the injection/mixing/settling regimes required for optimum water-removal from a meso-stable water-in-oil emulsion with an oil spill demulsifier. The use of a demulsifier injected into a recovery system, combined with decanting, did substantially reduce the volume of water in temporary storage tanks and the water content of emulsions for disposal/recycling

Abstract
This report describes the advent of emulsion inhibitors, and the types of testing employed to quantify their effectiveness in spill response scenarios. Chemicals normally sold as demulsifiers were an integral part of the new class of treating agents. One of the products, produced in Europe, could prevent emulsification when present in oil at ratios of 1:20,000 at 20°C and 1:1000 at higher than 10°C. However, lower temperatures negatively impacted emulsification of oil

Abstract
As a result of a two year program involving bench-scale, small-scale, and meso-scale testing, a new class of oil spill treating agents has been identified. These agents, called emulsion inhibitors, are highly oleophilic surfactants, which, when applied onto oil spills in very low concentrations, not only prevent mousse formation for significant periods of time but also cause a large reduction in oil-water inter- facial tension. Both of these promote the dispersion of the oil into the water column. The best chemicals to effect these results were found to be surfactants normally sold as oil spill “demulsifiers” (that is, surfactants that “break” oil spill mousse once collected). The best of these, a European-manufactured product was to found to prevent emulsification at dosages as low as one part inhibitor to 20,000 parts of fresh oil at 20° C. At dosages on the order of 1:1000, at temperatures higher than 10° C, the chemical also results in significant and rapid dispersion of the oil. For very low temperatures of highly weathered oil the performance of the chemical falls off sharply

Abstract
This field study was a combined chemical and biological investigation of the relative effects of using dispersants to treat oil spills impacting mangrove habitats. The aim of the chemistry was to determine whether dispersant affected the short- or long-term composition of a medium range crude oil (Gippsland) stranded in a tropical mangrove environment in Queensland, Australia. Sediment cores from three replicate plots of each treatment (oil only and oil plus dispersant) were analyzed for total hydrocarbons and for individual molecular markers (alkanes, aromatics, triterpanes, and steranes). Sediments were collected at 2 days, then 1, 7, 13 and 22 months post-spill. Over this time, oil in the six treated plots decreased exponentially from 36.6±16.5 to 1.2±0.8 mg/g dry wt. There was no statistical difference in initial oil concentrations, penetration of oil to depth, or in the rates of oil dissipation between oiled or dispersed oil plots. At 13 months, alkanes were >50% degraded, aromatics were ~30% degraded based upon ratios of labile to resistant markers. However, there was no change in the triterpane or sterane biomarker signatures of the retained oil. This is of general forensic interest for pollution events. The predominant removal processes were evaporation (≤27%) and dissolution (≥56%), with a lag-phase of 1 month before the start of significant microbial degradation (≤17%). The most resistant fraction of the oil that remained after 7 months (the higher molecular weight hydrocarbons) correlated with the initial total organic carbon content of the soil. Removal rate in the Queensland mangroves was significantly faster than that observed in the Caribbean and was related to tidal flushing

Abstract
Germination inhibition of the marine macrophyte Phyllospora comosa was utilized as a sub-lethal end-point to assess and compare the effects of four oil dispersants and dispersed diesel fuel and crude oil combinations. Inhibition of germination by the water-soluble fraction of diesel fuel increased following the addition of each of the dispersants; the nominal 48-h EC50 concentration of diesel fuel declined from 6800 to approximately 400 μl l-1 nominal for each dispersed combination. This contrasted with crude oil, where the addition of two dispersants resulted in an enhanced germination rate and an increase in nominal EC50 concentrations from 130 μl l-1 for the undispersed crude to 4000 and 2500 μl l-1. The results indicate that, while germination inhibition of P. comosa may be enhanced by the chemical dispersal of oil, the response varies with type of both oil and oil dispersant

Abstract
Primary consideration in this critical review was given to treating oil spills at sea with the intent of reducing the environmental impact of that oil if it should reach the shore. The general conclusions reached were: 1) In carefully planned and monitored laboratory and sea tests, oil has been effectively dispersed; but at many field tests and at accidental spills, reported effectiveness has been low--perhaps because of poor targeting and distribution of aerial sprays, because the oils were too viscous to be dispersable, or the observations of effectiveness were inconclusive; 2) The acute lethal toxicities of dispersant formulations currently in use are usually lower than those of the more volatile and soluble fractions of crude oils and their refined products; hence the toxicity of dispersed oil is due primarily to the oil and not to the dispersant; 3) Sublethal effects of dispersed oil observed in the laboratory occur in most cases at concentrations comparable to or higher than those expected in the water column during treatment of an oil slick at sea (1 to 10 ppm) but seldom at concentrations less than are found several hours after treatment (less than 1 ppm). Since the times of exposure in the laboratory are much longer than predicted exposures during slick dispersal at sea (one to three hours), the effects would be correspondingly less; 4) In open waters, organisms on the surface will be less affected by dispersed oil than by an oil slick, but organisms in the upper water column will experience greater exposure to oil components if the oil is dispersed. In shallow habitats with poor water circulation, benthic organisms will be more immediately affected by dispersed than untreated oil. Long-term effects of dispersed oil on some habitats, such as mangroves, are less, and the habitat recovers faster if the oil is dispersed before it reaches that area; 5) Because the principal benefit of dispersant use is to prevent oil stranding on sensitive shorelines, and because dispersability of oil decreases rapidly with weathering, prompt response is essential

Abstract
Killifish (Fundulus heteroclitus) and amphipods (Gammarus oceanicus) were exposed separately to either a No. 2 fuel oil, AP dispersant, or emulsions of the two in a static system. Both species exhibited a concentration-dependent response to all three treatments. However, emulsification of oil with dispersant clearly increased its lethal effect on killifish survival, but did not cause a differential change in behavioral parameters such as schooling, chafing, substrate nipping, activity, or depth preference. Killifish exposed to conditions of thermal or osmotic stress were more sensitive to the lethal effects of emulsions. In contrast, emulsions caused quantitative changes in amphipod activity and precopulatory behavior, but did not increase mortality beyond that caused by exposure to oil alone. Changes in salinity had little effect on amphipod sensitivity to emulsions, but decreasing temperature did result in increased survival

Abstract
A 3-year field study investigated reproductive success of Oceanodroma leucorhoa Vieillot exposed to oil and an oil/dispersant emulsion. Results indicate that initial breeding success was impacted by internal or external exposure to oil/dispersant mixtures in sublethal concentrations. Adults were more sensitive to pollutants during late incubation and early post-hatching periods. Nesting and hatching rates generally returned to normal in the second year after exposure

Abstract
The effects of crude oils, Corexit (0.1 mL), and 10:1 mixtures of crude/Corexit were studied using young Larus argentatus and adult plus young Oceanodroma leucorhoa to discover which components of oil were responsible for the effects observed and whether the toxicity could be modified by emulsification of the oil. Chicks of both species exposed to Corexit exhibited no significant changes in growth rate or organ weights compared to controls. Exposure to crude/Corexit mixtures resulted in similar effects in growth and organ weight found in birds dosed by oil alone

Abstract
A comparison has been made of the Mackay and Labofina tests for evaluating oil spill dispersants, in terms of showing correlation with effectiveness at sea. Both tests have been found to provide repeatable data on the efficiency of dispersants. Good agreement was obtained between the two tests for the efficiency ratings of five commercially available dispersants as well as for the identification of optimum surfactant combinations. When differences occurred between the two methods in the selection of optimum formulations, the cause was found to be the onset of wave damping affecting the Mackay test results. The major advantages of each test were speed and simplicity in the case of the Labofina test and the simulations of wind shear and wave-mixing action on dispersant-treated oil at sea for the Mackay test. While both methods showed significant disadvantages, both were considered useful in predicting dispersant performance at sea

Abstract
To minimize the environmental damage caused by catastrophic oil spills, the response community must work together to keep spilled oil from impacting sensitive areas and natural resources. Since no response method is 100% effective, it, is essential to consider the use of all available cleanup methods simultaneously. Preapproval for the use of dispersants by on-scene coordinators (OSCs) is necessary to maximize the benefits of dispersant application in a major coastal oil spill, and such preapproval is the responsibility of federal and state agencies. Over the past several years, the petrochemical industry, the response community, and the Region VI Regional Response Team (RRT VI), have studied the efficacy of various cleanup technologies. On the basis of their findings, in January 1995 RRT VI gave OSCs authority to use dispersants off the coasts of Texas and Louisiana under specific conditions. This was a significant shift from past philosophies, under which OSCs relied almost exclusively on mechanical recovery methods. Concurrently, industry has developed reliable and dedicated resources for the aerial application of dispersants in the Gulf of Mexico and has strategically located stockpiles of dispersants throughout the Gulf region. Delivery aircraft and trained controllers have been retained by industry to maintain a readiness and response posture that will maximize the effectiveness of an aerial application

Abstract
Authors provided technical data as criteria for the licensing and regulating of oil spill cleanup agents. Criteria included toxicity, performance effectiveness, and physical/chemical descriptions. Technical data was derived from a number of tests. Bioassays using fresh and saltwater established 96 h median tolerance limit (TLm) values for oil, dispersants, and oil/dispersant mixtures. Static, 24 h renewal and continuous flow bioassays were carried out. Researchers also conducted biodegradation tests, including monitoring biochemical oxygen demand and toxicity decay. Performance effectiveness was established by modification of the Federal Water Quality Association and U.S. Navy performance tests. The criteria for performance effectiveness included miscibility with seawater, emulsification percentage, amount of oil sinking, and amount of oil dispersed after two and six h. GLC, IR, a colorimetric method, Oil Red O method, and the weatherburn tests were used to identify pure dispersants and dispersants in seawater. From these tests, dispersants were observed to have the greatest potential for harm to the environment, while collecting and sinking agents were found to be relatively inert, insoluble, and probably nontoxic

Abstract
The introduction of oil into the hydrosphere subjects it to several transformation processes, as a consequence of the different environmental conditions which may alter its composition. These modifications include evaporation, solution and dispersion, oxidation (other chemical alterations), microbial decomposition, absorption by biota and sedimentation. The Jacob Maersk accident taking place at Leixōes harbor on January 29, 1975, seemed not to have catastrophic consequences when compared to similar accidents. However, only after a long time will it be possible to estimate the influence of the different fractions of oil, as well as the dispersants and detergents used on biotic communities. Studies still are being conducted in that area on the behaviour of populations due to the impact and of the ecological recuperation of the community structure. It should be emphasized that the use of dispersants began on January 31. 160 barrels were used on February 2. Trawler ships applied the dispersant at a rate of four barrels/hour, using pressure hoses as well as one spray system. The dispersant application--about 2,000 barrels or 200 liters each were used by mid-March--was by “FINA” technicians. Two dispersion processes were used: emulsification at 4% with water and subsequent distribution with fire monitors, and distribution of product by sprinklers and subsequent mixing with high pressure nozzles.

This represents a preliminary survey carried out during several months on the accident site, and to be continued later by the responsible entities
© 1977 with permission from APIThe introduction of oil into the hydrosphere subjects it to several transformation processes, as a consequence of the different environmental conditions which may alter its composition. These modifications include evaporation, solution and dispersion, oxidation (other chemical alterations), microbial decomposition, absorption by biota and sedimentation. The Jacob Maersk accident taking place at Leixōes harbor on January 29, 1975, seemed not to have catastrophic consequences when compared to similar accidents. However, only after a long time will it be possible to estimate the influence of the different fractions of oil, as well as the dispersants and detergents used on biotic communities. Studies still are being conducted in that area on the behaviour of populations due to the impact and of the ecological recuperation of the community structure. It should be emphasized that the use of dispersants began on January 31. 160 barrels were used on February 2.

Abstract
Previously, anomalous results from various laboratory dispersant effectiveness tests were believed due to the historic difficulties of replicating field conditions in the laboratory. Some variables were reported to cause differences in dispersant performance, such as the oil viscosity-i.e., both dispersant A and dispersant B exhibited poorer performance as the oil viscosity increase. Other test results showed an opposite trend. For example, dispersant A performed more effectively than dispersant B for Murban crude oil but B was better than A for the more viscous La Rosa crude oil. It is now believed that these inconsistent results are actually due to the chemical compositions of the crude oils. Various factors influence dispersant performance and some initial research directed at determining the mechanism of water-in-oil emulsion (mousse) formation has identified naturally occurring surfactants in the various crude oils. This will provide insight as to how these indigenous agents interacted with the surfactant package in the test dispersant to affect overall performance. Variations in dispersant performance for different crude oils are thus likely to be related to the water-in-oil emulsion formation of the particular crude oil. The results of this work indicate that dispersant treatment should be evaluated during spill situations even if the crude oil physical properties, such as high viscosity, might suggest that dispersant treatment would not be effective

Abstract
Chemical dispersants have a role in the cleanup of oil spills. However, neither dispersion nor any other current technique is a panacea for this purpose. There are situations where dispersants can be used for the benefit of our natural resources; but there are also instances where they should not be used. Similarly, there are conditions under which they are effective, as well as limits where they become ineffective. These aspects of the subject, as well as the mechanism of and basis for dispersing oil slicks, will be discussed. An understanding of the mechanism of dispersency is of prime importance in order to appreciate the behavior and variation in effectiveness of various generic types of surface active agents in promoting oil-in-water dispersions. In this regard, the presence of naturally occurring surfactants in crude oil and their properties are discussed. Even for the same chemical agent, its efficiency can vary due to the influence of many factors such as method application, degree of mixing, type of oil, temperature of water, amount of circulation in the body water, etc. Some chemicals can be more sensitive to a specific factor than others. Therefore, an appreciation of mechanism and the effect of environmental and application factors is necessary in order to assess the appropriate scope of application for dispersants as a tool for the handling of oil spills
