EC number: 939-581-9 | CAS number: -
Key study [Schlechtriem, (2013)]: OECD guideline 202 and EU guideline C.2. The acute toxicity of the test material to the freshwater invertebrate Daphnia magna has been investigated and gave a 48-hour EC50 value of 19.9 mg a.i./L.
Three studies were available for this endpoint on the test substance. A new study was selected as key study [(Schlechtriem, 2013)]. This study was run according to the OECD guideline 202 and EU guideline C.2. The acute toxicity of the test material to the freshwater invertebrate Daphnia magna has been investigated and gave a 48-hour EC50 value of 19.9 mg a.i./L.
Two other studies are available which gave a 48 -Hour EC50 of 16 and 0.96 mg a.i./L respectively [Kamp (1997) and Wetton (2000)]. The study of Wetton (2000) was rated Klimisch 2 and considered a supporting study. The study of Kamp was rated Klimisch 1. Although the obtained EC50 value was clearly lower than the EC50 value obtained in the study from Schlechtriem (2013), this value was considered an outlier and therefore not used for the PNEC derivation.
