The concentrations of heavy metals, Cd, Hg,
Pb, Cu and As in marine sediments from 138 sites located in the Beidaihe
near-shore area of Bohai bay, were analyzed to find out the distribution
characteristics of these heavy metals. Potential Ecological Risk index were
adopted to assess the heavy metals contamination, and the assessment results
indicated that the content of heavy metals in this area is in a low to moderate
level, while high values were found in the southwest and northeast region, and
the value in the middle region is comparatively low. The high pollution hazard
sites were close to the Renzaohe estuary and Shihe estuary and the high risk is
mainly led by Hg.
