Description of key information

With high probability not acutely harmful fish. No toxic effects occur within the range of solubility.

Key value for chemical safety assessment

Additional information

The acute toxicity of the test substance on Brachydanio rerio was investigated in two static GLP guideline study according to OECD 203 (BASF SE 2011; Laboratory of Ecotoxicity & Environmental Safety 2013). After 96 h an LC50 of >100 mg/L (nominal; BASF SE) and > 105 mg/L (nominal, Laboratory of Ecotoxicity & Environmental Safety) was determined which complies with the highest tested concentrations. Thus, no effects in the range of the water solubility could be detected and the test substance can therefore be considered as acutely not harmful to fish.

The results are supported by a prolonged (14 d) semi-static toxicity test of the test substance according to OECD 204 using zebrafish (Danio rerio). No effects occurred within the range of solubility. The NOEC and LOEC are above 105 mg/L (nominal).
