Effects of Suspended Solids on the Bioavailability of Chlordane to Daphna Magna

The importance of suspended solids'(SS) types and levels and associated organic carbon contents on the bioavailability of chlordane to Daphnia magna was researched. Test waters with SS levels of 0, 100, 500, and 750 mg/l contained a chlordane concentration which caused about 80% mortality of th...

Zusammenfassung:The importance of suspended solids'(SS) types and levels and associated organic carbon contents on the bioavailability of chlordane to Daphnia magna was researched. Test waters with SS levels of 0, 100, 500, and 750 mg/l contained a chlordane concentration which caused about 80% mortality of the test population in 48 hours. Both montmorillonite clay and pond sediments reduced bioavailability of the insecticide to D. Magna. SS characteristics were not a determining factor in the reduction of chlordane bioavailability as long as a threshold level of SS was present.
