Tirey, D., B. Dellinger, W. Rubey, AND P. Taylor. THERMAL DEGRADATION CHARACTERISTICS OF ENVIRONMENTALLY SENSITIVE PESTICIDE PRODUCTS. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/R-93/102 (NTIS PB93201127), 1993.


The thermal decomposition properties of the active ingredient of 16 pesticides have been theoretically examined. xperimental studies on 6 pesticide related materials were also conducted under controlled laboratory testing. xperimental studies of the high-temperature oxidation and pyrolysis of four key pesticide materials including the identification and quantification of products of incomplete 9 combustion (PICS) were conducted. he four pesticides were: ldicarb, Phorate, Atrazine, and Alachlor. ifth material, a polyethylene blend bag which is used as in Atrazine container, was also examined. The examination of the incineration ranking among the 16 subject pesticides indicated that they should be considered thermally fragile. owever, each pesticide In the controlled 14boratory testing decomposed to yield a large number of reaction intermediates. ore intermediates were consistently produced under pyrolytic conditions. ost of the intermediates were decomposed by 700 degrees C. ome persisted at the maximum testing temperature 1000 degrees C. t Appears that these materials m4y be Amenable to properly controlled, high-temperature incineration. t is concluded that open burning of spent pesticide bags may not significantly reduce their impact on the environment.
