Environmental Profile

Ecotoxicology:
Bees:Not toxic to bees.Birds:Dietary LC50 (8 d) for mallard ducks 4640 mg/kg.Fish:Not toxic to fish. Environmental fate: 
Animals:In rats, the major metabolites were 3-amino-5-chlorobenzoic acid, 3-aminobenzoic acid, 2,5-dihydroxybenzoic acid, 3,5-dihydroxybenzoic acid and 2,5-dichloroaniline.Soil:Undergoes microbial degradation in soil. Duration of activity is c. 6-8 w.Plant:In plants, chloramben is converted to a highly stable N-glucoside, which retards further degradation.
