57 poisonous substances themselves. These data indicate the prospects of the proposed peroxyacid method for degassing of mustard gas. Table 1. Toxicological characteristics of nitrogen mustards and products of their oxidative detoxification Number in order mustards and products of their oxidative detoxification LD 50 , mg/kg 1 Methyl bis(2-chloroethyl)amine 2,4 2 Methyl-bis(2-chloroethyl)amine N-oxide hydrochloride 75-125 3 Ethyl bis(2-chloroethyl)amine hydrochloride 1,05 4 Ethyl-bis(2-chloroethyl)amine N-oxide hydrochloride 50-100 5 Tris-(2-chloroethyl)amine hydrochloride 2,1 6 Tris-(2-chloroethyl)amine N- oxide hydrochloride 2,5-5,0 Compared to standard substances for degassing, such as calcium hypochlorite, dichloroethane, alkalis and chloramines of various compositions, the influence of peroxycarboxylic acids on the structural materials of objects is practically absent. Thus, the expediency of using peroxycarboxylic acids as highly effective and universal CWAs degassing agents has been shown. REFERENCES: 1. Glasser H., Chang D.P.Y., Hiekman D.C.J. All Waste Manage.
