Description of key information

With high probability acutely not harmful to fish.

Key value for chemical safety assessment

Additional information

As key study regarding acute toxicity to fish a static non-GLP test according to German Industrial Standard DIN 38412 part 15 using Leuciscus idus was identified (BASF 1981). After 96 hours of exposure a LC50 of ca. 460 mg/L was estimated, related to the nominal concentration and for a non-neutralized sample whereas for a neutralized sample a LC50 > 681 mg/L was found.

This result is supported by a study performed by Brixham environmental laboratory according to OECD 203 in 2003 on the seawater fish Scophthalmus maximus (turbot). The LC50 determined was 350 mg/L after 96 hours of exposure. In another study on the marine fish Pleuronectes platessa (Shepherd, 1982) according to OECD 203 the LC50 determined was approximately 290 ppm

These results indicate similar effects on freshwater and salt water as well.
