Environmental Profile

Ecotoxicology:
Bees:Non-toxic to bees.Birds:Slightly toxic to birds.Fish: LC₅₀ (96 h) for rainbow trout 12, crucian carp 70, bluegill sunfish 40 mg/l.

Environmental fate:
Animals:For metabolism in rats, see J. E. Bakke et al., J. Agric. Food Chem., 1967, 15, 628.Soil:In soil, microbial degradation is the most important route, involving hydrolytic cleavage of the methoxy group to give hydroxy metabolites, and dealkylation of the side-chains. WATER SOLUBILITY: 620 ppm at 20°C HAZARDS: (25E) Fish: LC₅₀ 20 mg/l (96 h) (rainbow trout); >32 mg/l (bluegill); 8.6 mg/l (goldfish). Bee: Nontoxic
