Abstract:

A standard dredged material bioassay was conducted with high levels of organotins to assess the toxicity and bioavailability of organotins associated with sediment and to determine if this sediment would qualify for ocean disposal. This study concluded that high levels of organotins in sediments do not a priori indicate a significant adverse impact on the marine environment after ocean disposal. The sediment tested would qualify for ocean disposal under the present guidelines administered by the Environmental Protection Agency and the Army Corps of Engineers. Particulate-phase tests were conducted with Acanthomysis sculpta mysid, Citharichthys stigmaeus flatfish, and Acartia tonsa copepod. Solid-phase tests were conducted with A. sculpta, Macoma nasuta clam, and Neanthes arenaceodentata polychaete worm. The bioassay also included an estimate of the potential for bioaccumulation of cadmium, chromium, copper, mercury, silver, pesticides, PCBs, petroleum hydrocarbons, and organotins. Survival was high in all particulate-phase and solid-phase tests. Originator-supplied keywords include Organotin-based antifouling coatings, Phytoplankton growth.
