CHROMIUM SPECIATION AND DISTRIBUTION IN SOUTHERN COASTAL SEA OF SHANDONG PENINSULA
山东半岛南部近海铬的形态和分布

Research indicated that ratio of paniculate chromium to total chromium is over 60%, a rather dominant chromiun speciation in this coastal sea. Hexavalent chromium is in less speciation, ratio of hexavalent chromium to total chromium is less than 3%. Trivalent chromium in dissolved state occupies a principal position, so that ratio of trivalent chromium to total dissolved chromium is more than 80%. Chromium distribution is high in mouth of Dingzi Bay but low in laoshan Bay.
