Abstract

Emamectin benzoate is one of the active ingredients of the anti‐sealice drug SLICE®. Ten‐day acute sediment lethal tests (10‐d LC50) of emamectin benzoate and its desmethyl metabolite (AB1) were conducted to determine LC50 values using a sensitive representative West Coast amphipod crustacean, Eohaustorius estuarius. The 10‐d LC50s of emamectin benzoate and AB1 to E. estuarius were 0.185 and 0.019 mg/kg wet weight sediment (0.146 and 0.015 mg/kg dry wt), respectively. The degradation properties of emamectin benzoate and AB1 during the 10‐d period were also measured and described. No obvious decay patterns were observed for either emamectin benzoate and AB1 over the 10‐d period. Environ. Toxicol. Chem. 2010; 29:1816–1820. © 2010 SETAC
