Environmental ProfileEcotoxicology:
Algae: EC50 (5 d) for Selenastrum capricornutum 0.023 mg/l.Bees:Not toxic to bees.50 (oral) >99µg/bee; (contact) >130µg/bee.Birds:Dietary LC50 (8 d) for bobwhite quail >5000, mallard ducks >500 ppm.Daphnia:LC50 (48 h) 12.66 mg/l.Fish:LC50 (96 h) for rainbow trout 5.5, bluegill sunfish 7.9 mg/l.Worms:LC50 (14 d) for earthworms 153 mg/ kg soil.Other aquatic spp.: EC50 for mysid shrimp (Mysidopsis bahia) 1.7 mg/l.
Environmental fate:
Animals:For metabolism in rats and rabbits, see C. Boehme & F. Baer, Food Cosmet. Toxicol., 1967, 5, 23.Soil:In soil, microbial degradation takes place, with oxidation of the methylthio group to hydroxy metabolites, and dealkylation of the side-chains. Median DT50 in soil 50 d (14-158 d). Koc 400, indicatingPlant:Metabolised by tolerant plants, and, to a lesser extent, by sensitive plants, by oxidation of the methylthio group to hydroxy metabolites, and by dealkylation of the side-chains. Degradation in plants is generally slow. SOIL PARTICLE ADSORPTION: Approx. 3 months residual activity at 2 kg/ha WATER SOLUBILITY: 33 ppm at 20°C HAZARDS: Fish: LC50 10.0 mg/l (96 h) (bluegill), 2.5 mg/l (rainbow trout). Bee: Nontoxic -
