Abstract To clarify the pollution sources and ecological health risks of heavy metals in soils influenced by coal mining activities, a typical coal mine in Yjinholuo Banner of Inner Mongolia was selected as the study area. A total of 180 surface soil samples were collected from the mining area between 2021 and 2023, and the concentrations of eight types of heavy metals were analyzed. The positive definite matrix factor decomposition model coupled with health risk assessment (PMF-HHR) was used to quantitatively evaluate the human health risks associated with heavy metals from different sources. The pollution of Cd and Hg in the study area is particularly serious, with Cd content in open-pit mines reaching 18 times the background levels of Inner Mongolia, the content of Hg in underground mines being 4.8 times higher, and higher levels of Cd, Cr and Ni in open pit mines than in shaft mines. The heavily polluted areas are mainly located in coal mining areas and along highways. The soil around the mine posed a moderate ecological hazard, with forestland, grassland and farmland showing high-risk levels. PMF source analysis identified five major pollution sources: combined industrial emissions and atmospheric deposition (18.0%), transportation (12.6%), agricultural activities and coal combustion (14.8%), mining (17.0%), and natural parent sources (37.6%). There was a notable cancer risk for both adults and children, with a higher risk observed in children. The main sources of cancer risk were industrial emissions and transportation, with oral ingestion being the dominant exposure pathway. The PMF-HHR model can effectively quantify the health risks from different sources.

Key words： heavy metals in soil mining method source analysis risk assessment PMF-HHR model
