Distribution of Dissolved Heavy Metals in Seawaters

The investigation was conducted from August 12 to August 25, 2003, along with the sea monitoring operations made by the North Sea Branch of the National Ocean Bureau of China. The heavy metal water samples at surface and bottom layers were collected from 48 stations in the whole area of the Bohai Sea (Fig. 2.47, Wang and Wang, 2007).

The average concentrations of dissolved Cd, Cu, and As were (0.31 0.12), (1.9 0.8), and (1.5 0.3) jUg/L (meaniSD) in August 2003, which were less than SWQSC-1, respectively, and there was no station with concentrations 

The d3mamics of sea water masses can also be regarded as an important factor influencing the spatial distribution of metals. The Bohai Sea exchanges sea water with the Yellow Sea through the Bohai Strait (mainly in from the north, out from the south ). Liaodong Bay is basically controlled by a cyclonic
