Description of key information

A study was performed to assess the effect of dioctyltin on the mortality and reproduction to Daphnia magna over a 21-day period. The method followed that described in the OECD Guidelines for Testing of Chemicals No 202. The test was preformed under semi static conditions using triethylene glycol and a vehicle.
The 21 day NOEC of DOTC in Daphnia magna for survival was 0.41 mg/L, the LOEC was 0.87 mg/L. The reproduction in any test solution was not statistically different from the control. Therefore, the 21 day NOEC for reproduction was ≥ 0.87 mg/L.
