Environmental Profile
Ecotoxicology: 
Bees:Toxic to bees, depending on the mode of application.Birds:Acute oral LD50 for bobwhite quail 39 mg/kg. Dietary LC50 (5 d) for mallard ducks 692, bobwhite quail 544 mg/kg diet.Daphnia: LC50 (48 h) 0.013-0.064 mg/l.Fish: LC50 (96 h) for bluegill sunfish 0.039, rainbow trout 3 mg/l. 
Environmental fate: 
Animals:In rats, following oral administration, 14C-disulfoton is rapidly absorbed, metabolised, and the radioactivity excreted in the urine. The main metabolites are disulfoton sulfoxide and sulfone, their corresponding oxygen analogues and diethylthiSoil:In soil, disulfoton is very rapidly degraded. The metabolism is similar to that in animals and plants. It exhibits medium to low mobility in soil.Plant:In plants, disulfoton is very rapidly metabolised. The metabolism is the same as in animals.
WATER SOLUBILITY: 25 mg/l at 20° C.
