Waste Disposal

The thiono-and thiolo-isomers of this mixture are 50% hydrolyzed in 75 minutes and 0.85 min- ute, respectively @ 20℃ and pH 13. At pH 9 and 70 ℃ , the half-life of Demeton is 1.25 hour, but an pH 1-5 it is over 11 hours. Sand and rushed limestone may be added together with a flammable solvent; the resultant mixture may be burned in a furnace with afterburner and alkaline scrubber .In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be dis- posed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
