Additional information

Acute toxicity to aquatic invertebrates was assessed in a 48 -hour study under static exposure conditons, following OECD guideline 202.

In a preliminary test at concentrations between 1 and 100 mg/l, concentration-related effects on mobility were seen. Based on such results, a main test was conducted at concentrations between 21 and 100 mg/l. Controls were run and were valid. All evaluations were based on nominal concentrations, as analytical monitoring showed that concentration of test substance varied only slightly more than ± 20 % of the nominal value.

Effect levels were determined at 24 h and 48 h after start of the study.
