Value expressed as active substance. 2) Test performed on salt compound. Value expressed as active substance. 3) Test performed on substance with purity <90%. Value expressed as active substance. 4) Effect concentration basis for calculation of PNEC. The most sensitive of the tested species was Lemna gibba, with a NOEC of 0.5 mg/l. Since both short and long term studies are available, and three trophic levels have been tested, an assessment factor of 0 is used for calculation of the predicted no effect concentration. Hence, the PNEC for dichlorprop-p is calculated to 0.05 mg/l..3 Bioaccumulation and persistence Dichlorprop and dichlorprop-p is not expected to bioaccumulate. Because Log P ow is low <3, bioaccumulation studies are not required. Dichlorprop-p is stable towards hydrolysis in ph 5,7 and 9. Degradation has been studied in two water/sediment systems, resulting in DT 50 of 4.6-5.3 days. The substance, to some extent, partitions in to the sediment, 28,4% was found after 30 days. In one anaerobic eutrophic pond study, dichlorprop-p is degraded much slower, DT 50 60 days. No major metabolites, exceeding 0%, has been found..4 Proposed interim water quality objective Since PNEC is 0.05 mg/l, the proposed water quality standard for dichlorprop-p is 0.0 mg/l..5 Comments Dichlorprop-p is mobile in soil and may reach ground- and surface water via leakage through the soil profile.
