Additional information
The acute toxicity of 3-hydroxy-1,1-dimethylbutyl 2-ethyl-2-methylheptaneperoxoate was evaluated with Cyprinus carpio in a study performed in accordance with OECD testing guideline 203 and GLP requirements.The LC50-value decreased from 2.5 mg/L after 24 hours of exposure to 1 mg/L at the end of the 96-hour exposure period. Hence, no stabilization of effects was observed at the end of the test period.
And the chronic toxicity was assessed with Pimephales promelas in accordance with OECD Guideline No. 210 and GLP requirements. The lowest NOEC was obtained for the post-hatch survival corresponding to 0.058 mg a.i./L.
The acute toxicity of 3-hydroxy-1,1-dimethylbutyl 2-ethyl-2-methylheptaneperoxoat was evaluated with Daphnia magna in a study performed in accordance with OECD testing guideline 202 and GLP requirements. The test substance did not induce acute immobilization of Daphnia magna at or below 1.8 mg/L after 48 hours of exposure (NOEC) with a 48h-EC50 of 4.8 mg/L (95% confidence interval between 4.2 and 5.8 mg/L).
A long-term toxicity test with Daphnia magna is also available performed according to OECD testing guideline 211 and GLP requirements. After 21 days of exposure, the 21 days EC10-reproduction was 0.84 mg/L a.i.
Toxicity to algae of 3-hydroxy-1,1-dimethylbutyl 2-ethyl-2-methylheptaneperoxoate was evaluated with Pseudokirchneriella subcapitata in a study performed in accordance with OECD testing guideline 201 and GLP requirements.The ErC50 (0 - 72 h) was estimated at 9.13 mg/L and the ErC10 (0 - 72 h) at 0.496 mg/L.
