Basic Concepts of Metal Pollution in Sediments

The overall aim of this document is to provide an in-depth understanding of the basic concepts concerning metal pollution of aquatic sediments. It seeks to explain the natural and anthropogenic origins of the heavy metals present in these sediments, as well as their transport processes, accumulation and release into the environment.The document stresses the importance of controlling these mechanisms to reduce risks and preserve the quality of aquatic ecosystems, while contributing to the sustainable management of sediment resources and the protection of public health.
