GUS plots of soil half-life vs log K_OC showing different criteria for persistent, mobile substances, including the GUS index of <1.8 for nonleachers in groundwater and >2.8 for leachers in groundwater. (A) Mobility criteria developed by the German Environment Agency (UBA) for soil and sediment (PM: half-life > 120 days, log K_OC < 4.0; vPvM: soil half-life > 180 days, log K_OC < 3.0). (B) Mobility criteria currently proposed by the European Commission (EC) for inclusion in the CLP regulation (PM: half-life > 120 days, log K_OC < 3.0; PM: soil half-life > 180 days, log K_OC < 2.0).
