Abstract
Acute and chronic toxicity testing with tributyltin (TBT) leachate derived from panels painted with antifouling paint was performed using the mysid species Acanthomysis sculpta (Crustacea, Mysidacea) . Chronic tests were performed in a flow-through dosing regime ranging in concentrations from 0.03 to 0.52 ug/L TBT. A 96-hr static renewal acute toxicity test was performed within a dose range of 0.25 to 0.66 ug/L TBT. In all experiments TBT was measured by hydride derivatization and atomic absorption detection. A 96-h LC50 value for juveniles was determined at 0.42 ug/L TBT. Reproductive effects were the most sensitive sublethal indicator of TBT toxicity. A chronic value of 0.14 ug/l TBT was determined above which a significantly reduced release of viable juveniles was apparent. Length and weight, in adult females, were affected in concentrations above 0.31 ug/L TBT. Based on the 96-hr LC-50 and the most sensitive chronic value measured, that for reproduction, an acute/chronic ratio of 3.0 was calculated.Keywords
