Abstract:

A study was conducted to establish the procedures necessary to assure that detoxified GB, VX, and HD would not be harmful to personnel handling the solutions and that solutions disposed of into water systems would not be harmful to people and aquatic organisms. The solutions tested were 10 sodium carbonate, pH 12.3 10 calcium hypochlorite, pH 12.6GB detoxified with 10 sodium carbonate, pH 10.5 VX detoxified with 10 calcium hypochlorite, pH 5.9 and HD detoxified with 10 calcium hypochlorite, pH 3.6. Solutions neutralized to pH 7 were also tested. Based on intravenous, intragastric, ocular, and cutaneous tests of the above solutions in mammals, immersion of fish and microcrustacea, and growth of aquatic plants, the following conclusions were reached 1 Personnel handling the unneutralized solutions should wear the same body protection prescribed for handling corrosive liquids. 2 The solutions should be diluted 11,000 to 110,000 before being handled by unprotected personnel. 3 Unneutralized 10 calcium hypochlorite should be diluted to 10 ppm and the other solutions should be diluted to 50 ppm before release into waters inhabited by fish. 4 All solutions must be neutralized before being released into waters containing aquatic plants the GB and VX solutions should also be diluted 1100,000 and the HD solution should be diluted 11,000,000.
