摘要
文章采用AAS法对延安市城区5个采样点TSP样品中12种主要金属元素的含量进行分析测试。应用富集因子法分析了每个金属元素的富集程度及在不同采样点的空间分布特点,判断出各金属元素的人为来源和自然来源的可能性;对主要金属元素的相关性进行分析;应用因子分析法得出12种金属元素的主要来源及其贡献率。
TSP（total suspended particle） samples collected at five sampling spots in Yan＇an City were analyzed by AAS,and12 kinds of main metal elements content in TSP were detected.Furthermore,the enrichment factor method was used to analyze the enrichment degree and the spatial distribution pattern of each metal element at different sampling spots.With the result of the analytic studies,the possibility of anthropogenic and natural sources deduced relating to each of the above metal elements,and the correlation amongst these metal elements was analyzed.Finally,by use of the factor analysis main sources and contribution ratios of the 12 metal elements could be obtained.
