  • The sequential extraction procedure was chosen for the study of speciation of Mercury in sediments of the Nanhai Lake. The fractions of watersoluble and exchangeable Hg are easy to release to the overlying water, and the sum of them account for 30.82 % of the total Hg. Furthermore, there exists positive correlation between these two fractions and the total Hg in overlying water, indicating high potential hazard to the Nanhai Lake. The content of humic acid Hg is the highest both in horizontal and vertical distribution and the correlation coefficient between humic acid Hg and organic matter is up to 0.72, indicating the contents of Hg and organic matter are highly correlated. Therefore, it is important that the organic matter is favor to immobilize Hg and reduce the potential Hg contamination of the Nanhai Lake.

Abstract: The sequential extraction procedure was chosen for the study of speciation of Mercury in sediments of the Nanhai Lake. The fractions of watersoluble and exchangeable Hg are easy to release to the overlying water, and the sum of them account for 30.82 % of the total Hg. Furthermore, there exists positive correlation between these two fractions and the total Hg in overlying water, indicating high potential hazard to the Nanhai Lake. The content of humic acid Hg is the highest both in horizontal and vertical distribution and the correlation coefficient between humic acid Hg and organic matter is up to 0.72, indicating the contents of Hg and organic matter are highly correlated. Therefore, it is important that the organic matter is favor to immobilize Hg and reduce the potential Hg contamination of the Nanhai Lake.
