Additional information

One study evaluating the acute toxicity of Fatty acids, C12-16 (even numbered) and C18-unsatd., methyl esters (CAS No. 1234694-02-0) to aquatic invertebrates is available (Migchielsen, 2010). This test was conducted according to OECD Guideline 202, under GLP conditions. Daphnia magna was exposed to the test substance for 48 h within a semi-static water regime, at a nominal loading rate of 100 mg/L. The test concentration was monitored during the study by gas chromatography determination. After the exposure period, no immobilization was observed in control or treatment groups and therefore, the EL50 (48 h) was determined to be ˃ 100 mg/L (WAF loading rate, nominal) and > 0.16 mg/L (average measured concentration).
