| Abstract |
Daphnids (Daphnia magna), scuds (Gammarus pseudolimnaeus), and midge larvae (Chironomus plumosus) were continuously exposed to toxaphene in a flow-through system. Exposure of daphnids for a complete life cycle (21 days) to 0.12, 0.28, 0.54, and 1.0 micrograms/l of toxaphene significantly (P<0.05) reduced production of young; the no-effect concentration was 0.07 micrograms/l. Toxaphene concentrations of 0.25 micrograms/l and greater significantly (P<0.05) reduced growth of scuds and concentrations of 3.2 micrograms/l and greater significantly (P<0.05) reduced emergence of midges. The no-effect concentrations were 0.13 micrograms/l for growth of scuds and 1.0 micrograms/l for emergence of midges. Daphnids continuously exposed to toxaphene accumulated residues after 7 days that were 4,000 times (based on organism wet weight) and water concentration of 0.06 micrograms/l. Whole body residues in midge larvae were below the minimum detection limit of 0.1 micrograms/g. Maximum acceptable toxicant concentrations (MATC) of toxaphene for the three species of aquatic invertebrates were estimated using reproduction of daphnids, growth of scuds, and emergence of midges as indicators of toxic effects. The MATC was estimated to be between 0.07 and 0.12 micrograms/l for daphnids, between 0.13 and 0.25 micrograms/l for scuds, and between 1.0 and 3.2 micrograms/l for midges. |
