Development of a new framework to estimate the environmental risk of heavy metal(loid)s focusing on the spatial heterogeneity of the industrial layout.

Industrialization and urbanization have increased the risk of heavy metal(loid)s coming from a wide range of pathways and processes. Regional environmental risk assessment mainly focuses on the regional functional layout, industrial orientation, and enterprise location. These aspects may generate immense environmental risks and hazards.

Interactive effects of multiple heavy metal(loid)s on their bioavailability in cocontaminated paddy soils in a large region.

Heavy metal(loid) pollution in large regions is often highly complex due to the coexistence and interactions of metal(loid)s and complex soil environments. However, the interaction effects of heavy metal(loid)s on their bioavailability in large regions remain obscure. Here, we identified the interaction effects of Pb, Cd and As on their bioavailability in cocontaminated paddy soils of Shaoguan City, China.
