Trace element distributions in aquatic sediments of Danang – Hoian area, Vietnam

摘要: Distribution of the trace elements Cr, Cu, Ni, Pb and Zn in surficial sediments river/sea environment Danang – Hoian area (Vietnam) was investigated to examine degree metal pollution caused by anthropogenic activities. Point sources from domestic industrial wastes are identified as dominant contributors element accumulation. Surficial River show extremely high total concentrations Cu (Average Concentration 295 μg/g), Ni (AC 112 396 μg/g) 429 that exceed assigned safety levels ER-M. Similarly, Han 188 282 contents. In marine Thanhbinh beach is also enriched (138 above guideline levels. contrast Cude dominated close background values.
