摘要
于2001 05～2002 04在青岛近海三个采样点采集了100多个大气气溶胶样品,用ICP测定了元素Al、Fe、Mn、Cu、Pb、Zn的浓度,讨论了这几种元素入海通量的季节变化和年平均值。结果表明,三类地壳元素春季在青岛近岸海域的沉降通量占全年的50%以上,而夏季不到10%;Cu秋季≈冬季(各占30%左右)>春季>夏季;Pb、Zn四季沉降通量的变化规律为冬季>春季>秋季>夏季。
Aerosol TSP samples were collected at three sites in Qingdao region from May 2001 to April 2002. The concentrations of six metals including Al, Fe, Mn, Cu, Pb, Zn were determined by means of ICP.,The temporal variations and the annual average were discussed. The results showed that the deposition flux of Al, Fe, and Mn are about 50% in the whole year in spring, and is the least in summer, accounting for less than 10%. The deposition flux of Cu in autumn is close to that in winter (about 30% of the (whole) year for each of the two seasons), and higher than that in spring and summer. The deposition fluxes of Pb, Zn are (decreased) in the order of winter>spring>autumn>summer.
