摘要
2006—2007年冬春季在武汉市湖北大学校区连续采集气溶胶样品,测定气溶胶元素组成,分析气溶胶样品总悬浮颗粒物(TSP)质量浓度,再结合污染源的特征元素组成来确定污染物的来源构成。结果表明:湖北大学校区大气气溶胶污染程度较轻,气溶胶元素以地壳元素为主,其次是具有代表性的人为污染物元素,再次是盐类元素。通过因子载荷分析和相关性分析显示,湖北大学周边地区的建筑源、交通源和餐饮源是湖北大学校区大气的主要污染源。
The aerosol samples were collected in Hubei University during winter-spring time (from November 2006 to April 2007) and their elemental composition was obtained. The results show that the atmosphere aerosol pollution is light, and the aerosol elements mainly come from the crust element, representative artificial pollutant elements and the salts element in this area. Results of the factor load and correlation analysis show that atmosphere polluants are mostly from construction source, transportation source, and the dining source around the Hubei scitech education area.
