Additional information

Effects of the test item on mobility of daphnids were investigated in a 48 -h static study under GLP conditions and following OECD TG 202. Due to the low water solubility, the test concentrations were prepared as water accomodated fractions (WAF) as described in OECD TG 23. The test concentrations could not be chemically verified due to the lack of a sufficiently sensitive method to determine the test substance in the test solutions up to its saturation limit. Therefore, the results are based on loading rate ("nominal concentrations"). The 48 -h EL50 was 46.9 mg/L (BASF, 2011).

Therefore, the substance is acutely harmful to aquatic invertebrates.
