[Stability of bituminous-salt mass-washing sarin, soman, and Russian VX destruction products in the aquatic environment and their effects of the sanitary conditions of water supplies].

The water environmental stability of O-isopropylmethyl phosphonate, O-pinacolylmethyl phosphonate, and O-isobutylmethyl phosphonate was studied. The very high hydrolytic stability of these products was established. The threshold and non-effective concentrations of O-isopropylmethyl phosphonate, O-pinacolylmethyl phosphonate, and O-isobutylmethyl phosphonate were determined, which affected the sanitary conditions of water bodies.
