Đánh giá mức độ tồn lưu Polyclo Biphenyl trong nước và trầm tích tại cửa sông Hàn, thành phố Đà Nẵng

Abstract

Polychlorinated biphenyls (PCBs) are a group of persistent organic substances under
the Stockholm Convention and highly toxic for human health. This study investigates PCB levels in water and sediment samples at 10 sampling sites from Han River estuary, Danang city, middle of Vietnam in rainny and dry season. In water samples, concentrations of total PCBs in the dry season were lower than those in the wet season with range from 0,223 - 1,688 g/L. For surface sediment samples, concentrations of total PCBs do not significantly differ and ranged from 49,294 - 178,285
µg/kg dry weight (DW).
