Additional information

A 21 -day Daphnia reproduction test was conducted by the Japanese Ministry of Environment at nominal concentrations of 10, 13, 18, 24, and 32 mg/L of Iron(+2)sulphate heptahydrate. Time weighted mean measured concentrations were determined to be 8.1, 10.0, 12.8, 18.1 and 23.7 mg Fe/L of test item.

After 21 -days exposure the NOEC was reported to be 8.1 mg Fe/L based on time weighted average concentrations
