Ecological risks of some heavy metals in sediment samples collected from downstream of the Red river

Abstract

This study aimed to assess the accumulation of some heavy metals such as Cu, Pb, Cd, and Cr in the sediments collected from downstream of the Red river from the south of Hanoi city to Nam Truc district, Nam Dinh province. Besides, the geological accumulation index (I_geo) and the potential ecological risk index were calculated to understand the impact of heavy metal content in the sediments on the ecosystem...
