Environmental Profile
Ecotoxicology:
Algae: EC50 (cell volume) for Chlorella fusca 111µmol/l (Pestic. Sci., 47, 337 (1996)).Bees:Not hazardous to bees when used as recommended.Birds:Acute oral LD50 for mallard ducks >2000 mg/ kg.Fish: LC50 (48 h) for bluegill sunfish 32, guppies 35 mg/l.
Environmental fate:
Animals:In mammals, the major metabolic route is N-oxidation to hydroxy-IPC.Soil:In soil, readily degraded by micro-organisms, with enzymic hydrolysis of the ester bond and degradation of the unstable N-phenylcarbamic acid to aniline and CO2, with further microbial degradation of aniline. DT50N-2-hydroxycarbanilate, which is found as water-soluble conjugates of glucose or other plant components. WATER SOLUBILITY: 0.25 g/l at 20°C
