Detection and Analysis of Residual Organic Harmful Chemicals in Soil Environment
In order to evaluate the impact of industrial activities and agricultural production on the residual levels of organic harmful substances in soil environment,advanced analytical techniques such as gas chromatography-mass spectrometry(GC-MS)and high performance liquid chromatography(HPLC)were used in this study.Soil samples from industrial and agricultural areas were taken as examples for systematic quantitative analysis of polycyclic aromatic hydrocarbons,polychlorinated biphenyls,and pesticide residues.By delving into the specific effects of soil types and agricultural activities on the residual levels of organic harmful substances in soil,the aim is to reveal the comprehensive impact of these factors on soil environmental quality.The results showed that the residual levels of polycyclic aromatic hydrocarbons and polychlorinated biphenyls in the soil of industrial areas significantly exceeded environmental safety standards,reflecting the significant impact of industrial emissions on the soil environment.Agricultural areas,on the other hand,have high concentrations of specific pesticide residues due to long-term pesticide use,reflecting the potential risks of agricultural production to soil quality.The research emphasizes the importance of soil pollution monitoring and management,which can provide scientific basis for formulating effective environmental protection measures.
