Environmental Guidelines
Hazards: Fish: LC50 >1000 ppm (rainbow trout, bluegill). Bird: LD50 350 mg/kg (mallard); LD50 140 mg/kg (pheasant). Bee: LC50 0:2 µg/bee
Soil Particle Adsorption: Acephate dissipates rapidly with half-lives of <3 and 7 days in aerobic and anaerobic soils, respectively. Major metabolite was CO2 in both soil types. TLC and soil column studies indicate acephate is mobile in most soils but that aged residues (excluding acephate and its degradate methamidophos) are immobile in sandy loam soil. Apparently most of the applied acephate and degradate methamidophos degrade to immobile compounds in 20 days
Water Solubility: Room temperature, 65%
Safety Guidelines
