Potentially toxic elements pollution in road deposited sediments around the active smelting industry of Korea

Abstract Potentially toxic elements (PTEs) were investigated in the different sizes of road deposited sediments (RDS) around the active smelting industry to understand their sources and to assess the pollution and ecological risk levels. The highest PTEs concentrations was shown near the raw materia...
