摘要
During the present study, the authors surveyed the bio-geochemistry in the coastal economic zone in Fujian Province.479 sediment samples were collected, and 52 elements, pH and organic carbon were analyzed. Heavy metals such as Cr, Cu, Pb, Zn, Cd, and Hg in the bottom sedimentary substances were comprehensively estimated in environmental quality, based on the standard of Quality of Marine Sediment(GB18668-2002).The analysis results indicate that coastal sea in Fujian is basically a clear band, accounting for roughly 70.8% of the whole sea area.
