Description of key information

The 28-day EC15 and the 28-day EC50 for the development rate of males and females and for the arcsin-transformed emergence rate of pooled sexes are >1000 mg/kg dry sediment. The overall 28-day NOEC of Chimexane NV in this sediment spiked study was 500 mg/kg dry sediment. The 28-day LOEC was 1000 mg/kg dry sediment due to a slightly reduced development rate of males. The key value for chemical safety assessment is a NOECstandard of 1041 mg/kg dwt, calculated by conversion of NOEC experiment to a standard organic carbon content.
