Additional information

In a 48 hours acute toxicity study, water fleas (Daphnia magna) were exposed to Oxooil LS 13 at the following nominal WAF loading rates: 0, 1.0, 1.8, 3.2, 5.6, 10, 18, 32, 56 and 100 mg/L. The resulting 48 hours EL50 value was 6.7 mg/L loading rate WAF. However, the total organic carbon (TOC) analysis used to determine test material concentration in WAFs was not reliable. Since Oxooil LS 13 water concentrations during the test period were not analytically confirmed and the batch/lot number is not provided, the present toxicity study is classified as reliable with restrictions according to OECD Guideline Nr. 202.
