Additional information

Two experimental acute toxicity data are available in the litterature: Broderius and Kahl (1985, 1995) have reported a LC50-96h of 37.9 mg/L in Pimephales promelas (fathead minnow) and Bengtsson-Be et al (1979, 1984) have described a LC50-96h of 45 mg/L in Alburnus alburnus (bleak). In addition, an OECD 201 compliant GLP study report is available for medaka, with an LC50-96h of 17.6 mg/L. This value is considered as the key value.
