Evaluating heavy metal pollution and potential risk of soil around a coal mining region of Tai’an City, China

Monitoring the spatial distribution characteristics of heavy metal pollution and evaluating its potential risks in the soil is essential for promoting regional socioeconomic development and maintaining the safety of the ecological environment. In this study, a representative coal mining region in Ta...

In this study, a representative coal mining region in Tai’an City, Chinas was selected as the study area, eight typical heavy metal elements (HMEs), i.g.
