Environmental ProfileEcotoxicology:
Algae:NOEC for Selenastrum capricornutum >0.4 mg/l.Bees:Toxic to bees. LD50 (oral) 360 ng/bee; (contact) 70 ng/bee.Birds:Acute oral LD50 for mallard ducks 490 mg/kg, house sparrows (Passer domesticus) 122 mg/kg, chickens 32-102 mg/kg. Dietary LC50 (8 d) for bobwhite quail 423 ppm.Daphnia:LC50 (48 h) 1.7mg/l.Fish:LC50 (96 h) for goldfish 0.18 (24 h), bluegill sunfish 0.002-0.010 mg/l, rainbow trout 0.007-0.051 mg/l, roach 0.25 mg/l, fathead minnow 0.12-0.54 mg/l, mosquito fish < 1 mg/l.Worms:LC50 (14 d) for Eisenia foetida 210 mg/kg soil.Other aquatic spp.: LC50 for Korean shrimp (Palaemon macrodactylus) 0.05 mg/l.Other beneficial spp.:Toxic to Collembola (J. A. Wiles & G. K. Frampton, Pestic. Sci., 47, 273 (1996)). Environmental fate:
Animals:In rats, dogs, and other mammals, following oral administration, rapid metabolism occurs, the principal metabolite being 3,5,6-trichloropyridin-2-ol. Excretion is principally in the urine.Soil:In soil, chlorpyrifos is degraded at a moderate rate; DT50 (lab.) 10-120 d (25 °C); field DT50 for soil-incorporated applications 33-56 d, for soil-surface applications 7-15 d. Primary route of degradaPlant:Non-systemic in plants, not absorbed from soil via the roots. Residues taken up by plant tissues are metabolised to 3,5,6-trichloropyridin-2-ol which is conjugated and sequestered.WATER SOLUBILITY: 2 ppm at 25°C
