Description of key information

The toxicity of TMQ to aquatic invertebrates (Daphnia magna) was tested in a static test according to EU Method C.2 "Acute Toxicity for Daphnia". After 48 hours of exposure, an EL0 of 6.3 mg/l, an EL50 of 56 mg/l and an EL100 > 100 mg/l were reported (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.
