Value expressed as active substance. ) Effect concentration basis for calculation of PEC. Test substance purity 88.8%. The most sensitive (acute effects) of the tested species was Mysidopsis bahia, with a LC 50 of mg/l. Since the acute/chronic ratio is low, a PEC based on long term effect does not guarantee appropriate protection against acute effects. Hence, the PEC is based on acute toxicity data. The lowest LC 50 of mg/l is divided by a factor of 00, which results in a PEC of mg/l..3 Bioaccumulation and persistence Bioaccumulation is not considered to be important because of rapid transformation of azinphos-methyl in water. Photolysis markedly accelerates in the presence of light and hydrolytic half-lives range between 4 and 87 days. The degradation rate is ph dependent, with decreasing half-lives with increasing ph..4 Proposed water quality objective Since PEC is. 0-6 mg/l, the proposed water quality objective for substance is 0-6 mg/l..5 Comments Mobility of azinphos-methyl in soil is low. The high K oc -value indicates that a quality objective for sediment may be relevant..6 Literature () European Commission Peer Review Programme. Azinphos-methyl Monograph (draft), 996.
