Contents and Distributions of Heavy Metals in the Surface Sediments from Northern Beibu Gulf

Abstract:

Contents and distributions of heavy metals in surface sediments from the northern Beibu Gulf were analyzed using atomic absorption spectrophotometer. The results showed that the contents of Cu, Pb, Zn, Cr and Cd were 14.22～26.68, 31.85～54.59, 60.19～90.93, 29.95～67.95 and 0.030～0.130 µg•g–1, respectively, and average were 18.21, 38.88, 78.00, 48.46 and 0.09µg•g–1. The reducing environments in northern Beibu Gulf were attributed to organic matters and sulfide. The distributions of heavy metals showed the trend of higher along the coastal area and lower in the offshore area, generally controlled by terrestrial inputs, as well as hydrological conditions, depositional environments and so on.
