Distribution, fate and ecological toxicity of some heavy metals in sediment: A case study from Day river downstream, Vietnam

In the study "Distribution, fate and ecological toxicity of some heavy metals in sediment: A case study from Day river downstream, Vietnam" the 50 surface sediment samples were collected along Day River downstream in July 2018 and January 2019 (25 sampling sites) to clarify the status, movement and potential risk of some heavy metals (Cr, Pb, Cu, Cd and Hg). The receptor model of Principal Component Analysis (PCA) was applied to track the source types of these metals.
