Assessment of heavy metal concentrations and its potential eco-toxic effects in soils and sediments in Dong Cao catchment, Northern Vietnam
H Mai, JL Maeghtb, C Valentin - Vietnam Journal of Earth Sciences, 2020 - vjs.ac.vn
The environmental risks associated with the concentration of metals in soils and sediments
due to their toxicological properties on living organisms are not yet sufficiently studied in
North Vietnam. Soil samples and sediments collected from three weirs (W1, W2 and W4) of
the Dong Cao catchment (49.7 ha) and from the downstream Cua Khau reservoir (CK) were
analyzed for heavy metal concentrations and geochemical parameters. Bioassays were then
applied to assess the toxicity of these soils and sediments based on a test of phytotoxicity …
