Spatial Distribution and Pollution Assessment of Potentially Toxic Elements (PTEs) in Surface Sediments at the Drinking Water Source Channel of Taipu River in China

With the integration strategy of the Yangtze River Delta rising to the height of the national strategy, it is crucial to ascertain pollution, ecological risks, and possible sources of potentially toxic elements (PTEs) in the sediments of the drinking water source channel Taipu River across the core...
