摘要：

Purpose: The spatial distribution and potential ecological risks of potentially toxic elements (PTEs) such as Sb, As, Cu, Zn, Pb, and Cr in sediment samples from the Qingfeng River were evaluated. This study aims to reveal the current status of sediment quality in the Qingfeng River and provide a scientific basis for its remediation and further comprehensive management. Materials and methods: Descriptive analysis and inverse distance weighted method were used to investigate the concentration and spatial distribution of PTEs in sediments. The ge...
