| 摘 要： | 2006年7月～2007年10月对北黄海海域大气气溶胶及其负载的营养元素在春、夏、秋、冬4个季节的浓度分布进行了调查.结果显示,大气总悬浮颗粒物(TSP)、大气颗粒态总碳、钠、钙、镁、氮和磷都呈现出明显的季节变化,但是不同元素的季节分布规律不同.TSP、总碳和氮浓度都是春冬季较高,秋季次之,夏季最低.钠的季节变化与TSP不同,为夏季>冬季>春季>秋季,水溶性钙和镁分别呈现出春季>秋季>冬季>夏季及秋季>冬季>春季>夏季的季节变化.而水溶性磷酸盐浓度夏季最高,春季次之,秋冬季浓度很低.春、夏、秋、冬4季TSP、总碳和氮在不同采样海域的分布特征类似,即在离岸较近海域采集的样品TSP浓度较高,尤其是靠近辽东半岛和山东半岛海域.钠在不同采样海域的分布与TSP完全不同.各航次内钙、镁在不同采样海域的分布特征较复杂,呈现出与TSP和钠都不尽相同的分布特征.

| Abstract: | The seasonal distribution of atmospheric aerosol and the nutrient elements on aerosol particles were surveyed over the North Yellow Sea from July 2006 to October 2007.The results showed that there was a clear seasonal variation for atmospheric particulates and particulate carcon,sodium,calcium,magnesium,nitrogen and phosphor.The concentrations of TSP(Total Suspended Particles),total carbon and nitrogen were the highest ones in spring and winter,and the lowest ones in summer.Sodium had a highest value in sum... |
