The potential hazard of contamination directly depends on the presence and concentrations of mobile and biologically available element species. The mobility and availability of elements are known to depend on the chemical species of elements and the type of their bonding with the soil matrix. A three-step sequential extraction procedure (BCR-SEP) was used to determine the concentration of heavy metal...
The sedimentary environment's change will be recorded in the sediments, which can be manifested by the variation of the sediments' physicochemical features. To study the trophic evolution and heavy metals pollution processes, the sedimentary geochemical properties of the core Huoshaohei (HSH) sediments, such as grain size, nutrients, heavy metals, etc, are analyzed. The nutrients in the sediments...
