施用于农田的农药大部分残留于土壤环境介质中.农药在土壤的吸附一解吸是农药在土壤一水环境中归趋的主要支配因素,也是支配该农药在环境中的生物有效性和持久性的重要因素之一.但是随着人类活动的干预,许多地区的土壤已经被多种重金属污染.本文以除草剂草萘胺和重金属铅的复合污染为研究对象,通过红土与黄棕壤两种土壤对不同浓度草萘胺和铅复合污染的吸附解吸实验,得出以下结论:添加铅后土壤对草萘胺的吸附量和解析量均有提高.黄棕壤土对草萘胺的吸附量和解析量均大于红壤.
Most of the pesticides applied to farmland remains in the soil media.Adsorption of pesticides in soil,the desorption of pesticides in the soil water environment in the fate of a major dominant factor,but also dominate the pesticide bioavailability in the environment and sustainability of the important factors.But with the intervention of human activities in many areas of heavy metal contamination of soil has been.In this paper,herbicide-naphthylamine and heavy metal pollution of lead compound as the research object,through the red soil and yellow brown grass of different concentrations of two soils naphthylamine and compound pollution of the adsorption and desorption experiments,the following conclusions:Add Lead in Soil naphthylamine on the grass and analytical adsorption volume has increased.Yellow-brown soil on the adsorption capacity of grass-naphthylamine and analytical volume greater than the red soil.
