Additional information
Short term ecotoxicological data are available for chloromethane. All data - experimental as well as QSAR estimates - give comparable results for fish and aquatic plants. They indicate a relatively low toxicity. It therefore seems justified to derive a PNEC based on the valid short term study with Daphnia magna, this is the most sensitive result (EC50 of 200 mg/L).
Conclusion on classification
Not classified for environment according to Regulation EC No 1272/2008 (CLP).
Not classified for environment according to Directive 67/548/EEC (DSD).
