农药在土壤上吸着/解吸及其对生物利用率影响的研究进展

Sorption and desorption of pesticides on/from soil and the effect of that on bioavailability

正确预测有机污染物在环境中的归宿 ,在很大程度上依赖对它们的吸着 -解吸动力学行为的认识。自 2 0世纪 80年代起 ,吸着 -解吸动力学逐渐受到重视。本文介绍了国内外有关农药在土壤 /沉积物上的吸着 -解吸动力学和吸着 -解吸对土壤有机污染物的生物利用率的影响等方面的近期研究成果 ,着重从实验方法、模型。

To accurately predicate the fate of pollutant in the environment, to a great extent, depends on the sorption/desorption kinetic, so more attention has been given to those since 1980s. The achievements in sorption/desorption were reviewed, especially on experimental methods, models and mechanism of slow sorption/desorption. Meanwhile, the effect of sorption/desorption on bioavailibility was also discussed.
