Environmental ProfileEcotoxicology:
Algae:EC50 for Scenedesmus subspicatus 0.1 mg/l.Bees: LD50 (oral and contact) >110 mg/bee.Birds:Acute oral LD50 for mallard ducks and bobwhite quail >2150 mg/kg. Dietary LC50 (8 d) for bobwhite quail and mallard ducks >10 000 mg/ kg.Daphnia:LC50 (48 h) 25 mg/l.Fish:LC50 (96 h) for rainbow trout 3.9, carp 4.9, bluegill sunfish 10 mg/l.Worms:LC50 (14 d) for earthworms 140 mg/ kg soil.
Environmental fate:
Animals:Rapidly oxidised by rat liver microsomal oxygenases via dechlorination, O-demethylation and side-chain oxidation (J. Agric. Food Chem., 1989, 37, 1088).Soil:Major aerobic metabolites are derivatives of oxanilic and sulfonic acids. DT50 in soil c. 20 d (field). Koc 121-309.Plant:In plants, metabolism involves natural product conjugation of the chloroacetyl group, and hydrolysis and sugar conjugation at the ether group. Final metabolites are polar, water-soluble, and non-volatile. -
