I. Toxicity to fish:

The key study was performed in 1995 by BASF with Brachydanio rerio (Zebra fish) and revealed an LC50 in the range of >4600 -10000 mg/L. Test was performed in accordance with OECD guideline 203, exposure time was 96h. An additional acute toxicity supporting study is available for Golden orfe (LC50 (48h) >1600 mg/L). However, the test design shows several deficiencies compared to relevant guidelines.

II. Toxicity to invertebrates:

Acute toxicity towards Daphnia magna was examined in a test according to EEC directive 79/831 EEC, Annex V, C2.

The test revealed a no-effect concentration (EC0) of 500 mg/L, whereas an EC50 of >500 mg/L was determined.

III. Toxicity to algae:

Possible toxic effects of the test substance towards algae were investigated in a study which followed German standard DIN 38412 (Part 9). After an exposure time of 72 h following effect values were observed: EC10 = 22.2 mg/L; EC50 > 500 mg/L.

IV: Aquatic microorganisms:

A test according to OECD guideline 209 resulted in an EC50 >1000 mg/L.
