The metal elements (Al, Fe, Mn, Cr, Co, Ni, Cu, Zn, As, Pb and Ca) in the bottom sediment of the Changjiang Estuary and its adjacent continental shelf of the East China Sea were studied to map their spatial distribution and to assess their potential risk to the marine biota. These metal concentrations except Ca were generally higher in the inner shelf and northeastern part, and were found to decrease from the coast to the offshore of the Changjiang Estuary. Sedimentary Ca was most abundant in the outer shelf sediments and decreased in inner shelf. Arsenic (As) appeared to be contaminated due to economic development from 1980s in the inner shelf overall, but the potential ecological risk from the selected metals was low in the coastal sea off the Changjiang.
对长江口及其东海毗邻陆架区的海底沉积物中的金属元素（铝、铁、锰、铬、钴、镍、铜、锌、砷、铅和钙）进行了研究，以绘制其空间分布图，并评估其对海洋生物群的潜在风险。除钙之外，这些金属元素的浓度在内陆架和东北部地区通常较高，且从长江口沿岸向近海递减。沉积钙在外陆架沉积物中最为丰富，在内陆架则减少。总体而言，由于20世纪80年代以来的经济发展，内陆架的砷似乎受到了污染，但长江口近海海域所选金属的潜在生态风险较低。
