If this process is effective, the of! may thus be prevented from moving into sensitive environments or stranding onshore, thereby eliminating or reducing damage to important coastal habitats, marine life, or coastal facilities.

Few published studies exist on the fundamental science concerning how dispersants act on oil in water. Most of the published studies on oil spill dispersants describe laboratory en cl sea tests of commercially available products.

Laboratory studies of dispersants currently in use have shown that their acute lethal toxicities are usually lower than crude oils and their refined products. A wide range of sublethal effects of dispersed oil has been observed in the laboratory.

caused less chronic environmental damage than of} alone, the committee recommends that additional ecological studies be conducted, under controlled or naturally established water circulation regimes in shadow environments, to help define the conditions under which dispersant use will be effective and environmentally safe. Because the principal biological benefit of dispersant use is prevention of oil stranding on sensitive shorelines, and because dispersability of of} decreases rapidly with weathering, prompt response is essential.

and dispersed oil with suspended particulates, sediments, plankton, and benthic organisms to establish a better quantitative basis for comparing the adhesion properties of untreated of} and dispersant-treated oil. Research in the mechanics of dispersed of} resurfacing and spreading to guide improvement in dispersant application strategy and to reduce possible impact of dispersed of} on fish larvae and marine birds and mammals.
