Description of key information

The toxicity of TMQ to aquatic algae (Scenedesmus subspicatus) was tested in a static limit test according to EU method C. 3 "Algal Inhibition Test". After 72 hours of exposure, an EL0 >= 100 mg/l was concluded (Bayer AG, 2000). Due to the heterogeneous composition of the test substance, the effective loading (EL) was determined upon water accommodated fraction (WAF) without chemical analysis.

Key value for chemical safety assessment
