摘要：

A model for surfactant sorption proposed by Di Toro et al. (1) is compared to riverine monitoring data for linear alkylbenzenesulfonate (LAS). The model predicts sorption distribution coefficients (Kd) to within one order of magnitude of measured field values. Field determined values of Kd range from 11 to >24 for sediment/interstitial waters, and from 1000 to >5700 for suspended solids/overlying waters. The model provides an interpretive framework for evaluating the safety of monitored LAS concentrations to aquatic organisms, by enabling prediction of free concentrations of LAS in sediment interstitial waters. © 1990.
