Study on Distribution and Variation of Heavy Metal Pollution in Guangxi Coastal Seawater during Dry Season

Abstract:

To study the distribution of heavy metal pollution in Guangxi coastal water, we set up 10 monitoring stations in Guangxi coastal water, monitored and analyzed Hg, Cu, Pb, Cd, As, Zn and Cr in each monitoring stations during 2007 and 2009 dry season. The results show that the heavy metal pollutants distribution concentration of Guangxi coastal water during the dry season can meet Grade I sea water quality standard. From 2007 to 2009, heavy metal pollution of Guangxi coastal water is reduced. Heavy metal contents in seawater of all stations is decreased expected Cu, whose content is slightly elevated. And besides the reduction of As is small, other heavy metals declined obviously, theirs contents are all below or near the detection limit. Cu contamination of seafood proliferative zone and dredged sludge dumping areas need to be strengthened supervision.
