【摘要】 采用溶剂萃取石墨炉原子吸收光谱法测定了龙口海港及邻近海域海水中溶解的Zn,Cu,Pb,Cd,Cr。研究表明:重金属污染与工业废水和生活污水排放以及船舶、码头的污染密切相关。该海港5月重金属污染较重,而8月因大量减少污水排放,使水质得到明显改善,并接近山东半岛近海的重金属含量水平。更多还原

【Abstract】 Dissolved Zn, Cu, Pb, Cd, Cr in sea water were determined after a preconcentration-complexation treatment by graphite furnace atomic absorption spectroscopy.Study results indicate that pollution of heavy metals and drainage of domestic sewage and industrial waste and discharge of shipping possess a fairly relation. Pollution of heavy metals in this harbour was serious in May 1991. Whereas state of water mass occurred pronounced improvement due to bulky decreased dischange of sewage in Aug. , 1991. So that content of heavy metals in sea water of this harbour is similar to that in coastal sea water of the Shandong Peninsula.更多还原
