Pesticides, when treated with sodium biphenyl reagent, were decomposed to the extent of 80 to 99%. However, when these compounds were treated with a mixture of metallic sodium and liquid ammonia, 15 of the 19 compounds were completely degraded. When metallic lithium was substituted for metallic sodium, the mixture was less effective but still completely degraded 8 of 19 compounds. The decomposition products resulting from these reactions were not tested for toxicity. The pesticide formulations were incinerated, either singly or mixed, at 900C. Analyses of the volatile products revealed that at least four hazardous gases (chlorine, hydrogen chloride, hydrogen sulfide, and nitric acid) were produced.
