Analysis of Heavy Metal Sources and Pollution Assessment in Surface Soil of Hydraulic Engineering,Environmental Geology
To gain a deeper understanding of the sources of heavy metals and their distribution and migration patterns in soil,re-search is conducted on the source analysis and pollution evaluation methods of heavy metals in the surface layer of hydraulic,environmen-tal,and geological soils.Taking the hydrogeology and environmental geology of a certain city as the research area,surface soil was col-lected at different collection points,and the samples were subjected to microwave digestion treatment.The source of heavy metals was an-alyzed using the positive definite matrix factorization method,and pollution was evaluated using the geological accumulation index and risk assessment code.By selecting 7 heavy metal elements as key pollutants for research,atomic absorption spectroscopy(AAS)was used to analyze the content of these metal pollutants in the surface layer of hydraulic,environmental,and geological soil in the study area,and their sources were analyzed.The experimental results can quickly and efficiently determine the content of heavy metals in soil,which helps to accelerate the monitoring and evaluation of heavy metal pollution.
