Additional information

Several daphnid values are reported, including several studies of high quality. Acute values (24-48 hour EC50) range from 73 to 226 mg-B/L for Daphnia magna. Data for other daphnids are reported but are of low reliability, also reported acute values in the 100-180 mg-B/L range for Ceriodaphnia dubia and Simocephalus vetulus.

Maier and Knight (1981) reported that water hardness had no effect on the acute toxicity to the midge Chironomus decorus, with a 48-hour EC50 of 1376 mg-B/L.
