Description of key information

Daphnia magna were exposed in static conditions to paradimethoxybenzene according to OECD 202 and GLP. The 48-hour EC50 was calculated to be 52 mg/L ( based on mean measured test item concentrations calculated as the geometric mean over all measurements per test concentration during the test period).

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
52 mg/L

Additional information

Only two studies were available. One of them (RCC, 2006) quoted as reliability 1 according to Klimisch, was selected as key study; the other one of reliability 2 (Palla, 1983) was selected as supporting study.
