Abstract Taking a chemical industrial site in Jilin City as a case study, a preliminary monitoring analysis and environmental assessment were conducted on the surrounding soil. The study analyzed the current status of soil contamination, the primary sources of pollutants, potential contaminants, and their spatial distribution characteristics. Utilizing methods such as field sampling and exploration, soil samples were collected from different functional zones of the chemical plant and tested for heavy metals. The detected heavy metals included arsenic、cadmium、copper、lead、nickel、mercury、and hexavalent chromium , with arsenic and nickel levels exceeding standard limits at some sampling points. Based on the test results, this paper proposes corresponding recommendations for soil pollution prevention and control measures, providing a scientific basis for soil environmental protection and management.
