ABSTRACT
To understand the status of soil heavy metal pollution and its impact on human health, the Rucun
area of Wutai County, Xinzhou City, Shanxi Province, was selected as the research area. Using SPSS19
statistical software, the land accumulation index method, potential ecological hazard index method, and
health risk assessment model were used to evaluate the degree of soil heavy metal pollution, ecological
risk, and health risk in the area. The results indicate that the degree of heavy metal pollution in the
soil of the study area is relatively low, and there are light pollution points for As and Pb; The degree
of ecological risk is relatively low; As, Cr, and Pb elements pose a significant non carcinogenic health
threat; As and Cd elements pose a risk of carcinogenesis; The average value of the total cancer risk
index is between 10-6 a nd 10-4, which does not pose significant harm to the physical health of local
residents. However, it exceeds the soil management benchmark value of 10-6 proposed by the US EPA,
and prevention measures should be strengthened. The ecological risk and health risk assessment of
heavy metals in soil quantitatively evaluates the risks of heavy metals in soil, which has a good guiding
and exemplary role in risk prevention.
