Additional information

One reliable toxicity study to microorganisms is available. The toxicity to microrganisms was studied by following to OECD TG No. 209 and in compliance with GLP. Following a preliminary range-finding test, activated sewage sludge was exposed to aqueous dispersions of the test item at nominal concentrations of 10, 18, 32 and 56 mg/L (five replicates of each) for a period of 3 h. Toxicity to micro-organisms was assessed by measuring the respiration rate. No statistically significantly toxic effects were shown at the test concentrations of 10, 18 and 32 mg/L, however statistically significantly toxic effects were shown at the test concentration of 56 mg/L. Based on these results the No Observed Effect Concentration (NOEC) after 3 h exposure was 32 mg/L.
