[Experimental rationale for the maximum allowable concentrations of organic phosphorus toxic agents in the soil].

Hygienic standardization of soil sarin, soman, and Vx levels established the threshold and subthreshold concentrations of the agents from the general sanitary, translocational, and migratory water and migratory air safety indices. Substantiation of their maximum allowable concentrations (MAC), the limiting safety index is a migratory air index for soman and sarin and a migratory water index for Vx. Soil MACs of sarin, soman, and Vx are 2 x 10(-4), 1 x 10(-4), and 5 x 10(-5) mg/kg, respectively.
