Toxicology
(Rat): Oral LD50 127 mg/kg; Dermal LD50 423 mg/kg. Severely irritating to skin, eyes, upper respiratory tract. Telone*: Oral LD50 224 mg/kg (female); 300 mg/kg (male). Inhalation LC50 904 mg/kg(female); 855-1035 mg/kg?(male). (Rabbit): Dermal LD50 333 mg/kg.
Environmental Profile
Ecotoxicology:
Algae: Slightly toxic.Bees:50 (90 h) 6.6 μg/bee.Birds:50 for bobwhite quail 152 /kg. Dietary 50 (5 d) for mallard ducks and bobwhite quail >10,000 mg/kg diet.Daphnia:50 (48 h) 6.2 mg/l. Fish:50 (96 h) for rainbow trout 3.9, bluegill sunfish 7.1 mg/l.Worms:Initially toxic to earthworms; not persistent, therefore re-colonisation is very quick.Other aquatic spp.:Moderate acute toxicity.
Environmental fate:
Animals: Excretion in rats occurred primarily as the mercapturic acid conjugate and its corresponding sulfoxide. Soil:Non-persistent in soil, undergoing hydrolysis to the corresponding 3-chloroallyl alcohols (C. E. Castro & N. O. Belser, J. Agric. Food Chem., 1966, 14, 69).
WATER SOLUBILITY: 0.1%.
