Description of key information

No mortality was observed in bleak (Alburnus alburnus) exposed for 96 hours to brackish water (7‰ salinity),containing Chloroparaffin huls 40G (C15.5; 40% chlorination) and Witaclor 50 (C14-17; 50% chlorination) at up to 5000 mg/l (nominal) or with a Cereclor S52 (C14-17; 52% chlorination) at up to 10,000 mg/l (nominal). Therefore, the 96-h LC50 can be considered as greater than 5000 mg/l (Linden et al. 1979).
