Abstract

Each year, pollutant from industrial sources, ports, agriculture sources and domestic sources discharges to BachDang estuary. Scientists are interested in studying mercury very much because it is toxic and bioaccumulation. In this paper, some kinds of mercury such as total mercury (Hgi), dissolve mercury (Hgi), methyl mercury (HgMe) and mercury linked suspended solid (HgTss) were measured in water at BachDang estuary. Concentration of total mercury was lower than limited permit QCVN 10:2008/BTNMT (1 pg/1). In water, kind of mercury linked suspended solid is main composition, rate over 50 % (maximum was 74 %). Concentration of mercury (total mercury, dissolve mercury, methyl mercury and mercury in TSS) in rainy season was higher than that in suimy season. Concentration of mercury was changed in rainy season and stabilized in sunny season.
