由于果农在喷洒农药时存在不规范操作的情况,容易产生有机氯农药残留量超标的问题.为此,提出苹果园土壤中有机氯农药的污染特征及修复技术研究.采集土壤样品并采用气相色谱-三重四级杆质谱联用法测定有机氯农药类型和浓度,根据污染物浓度计算综合污染指数.分析土壤有机氯农药组成特征和时空分布特征,针对有机氯农药污染,采取表面活性剂强化电动-过硫酸钠修复方法进行治理并分析修复效果.测试结果表明,该技术修复后的污染土壤中各种有机氯农药的浓度大大降低,去除率达到了 90%以上,证明了该方法的修复效果.
Research on Pollution Characteristics and Remediation Techniques of Organochlorine Pesticides in Apple Orchard Soil
Due to the non-standard operation of fruit farmers when spraying pesticides,it is easy to cause the problem of excessive residual organic chlorine pesticides.Therefore,the pollution characteristics and remediation techniques of organochlorine pesticides in ap-ple orchard soil are proposed.The study collected soil samples and determined the type and concentration of organochlorine pesticides using gas chromatography-triple quadrupole mass spectrometry.The comprehensive pollution index is calculated based on the pollutant concentration.The composition and spatiotemporal distribution characteristics of soil organochlorine pesticides is calculated.The paper adopted a surfactant enhanced electric sodium persulfate remediation method to address organochlorine pesticide pollution and analyze the remediation effect.The test results show that the concentration of various organic chlorine pesticides in the polluted soil remediated by this technology is greatly reduced,and the removal rate has reached over 90%,which proves the remediation effect of this method.
