... Serious acute and chronic ecological damage can occur, and economies and community health can be affected (Atlas and Bartha 1973; Kelso and Kendziorek 1991; Overton and others 1994~. Because of the danger to health, ecology, and public relations represented by large oil spills that overwhelm natural capacity for purification, new marine biotechnology approaches are needed to move the "technology" forward for cleaning up impacted coastal and marsh environments.

... OIL SPILL EFFECTS Oil spills affect ecosystems in three ways: smothering plants and animals, massive input of organic carbon upsetting nutrient cycling, and toxicity (NRC 1985~. · Smothering.

From page 63...
... For the normal oil slick on the marsh surface, only the organisms near the air/ water interface of the oil will encounter high concentrations of toxins. When the oil has been dissolved into the water column, as happens with dispersants, deep water biota not normally affected by oil spills will encounter oil.

... Similar products proposed for use in oil spill response in these coastal environments have undergone a comprehensive series of tiered tests under federal guidelines (Portier 1991~. Few products have been approved to date for US Coast Guard use in impacted marsh environments.

... Development of Risk Assessment Strategies for Marsh Habitats Finally, there still is a need to predict risk and relative impact. Assuming logistics and intervention approaches have become more sophisticated through the years, there continues to be the problem of developing the environmental management tools to determine when and if a marine biotechnology delivery system will minimize and/or facilitate postspill remediation (Portier and Ahmed 1988; Smith and Portier 1997~.
