High-volume air samplers were used to collect aerosol samples on Whatman 41 air filters at the Canadian air sampling stations Burnt Island, Egbert, and Point Petre. The samples were analyzed for trace elements by neutron activation analysis. Air concentrations of over 30 trace elements were determined. Factor analysis, elemental ratios, and enrichment factor analysis were used to determine source-receptor relationships at the three different sites. Factor analysis exhibited trends that indicate oil and coal combustion, road salt, mining, incineration, and smelting as anthropogenic sources to aerosols of the rural Great Lakes. Elemental ratios showed that the Na to Cl ratio in the Great Lakes aerosol is similar to that found in sea water. Enrichment factor analysis revealed elements with non-crustal sources including the elements Ag, As, Br, Cl, Cu, I, In, Sb, Se, Sn, W, and Zn.
在加拿大的空气采样站伯恩特岛、埃格伯特和彼得角，使用大容量空气采样器在沃特曼41号空气过滤器上采集气溶胶样本。通过中子活化分析对样本中的微量元素进行分析。测定了30多种微量元素的空气浓度。使用因子分析、元素比率和富集因子分析来确定三个不同地点的源 - 受体关系。因子分析呈现出的趋势表明，石油和煤炭燃烧、道路盐分、采矿、焚烧和冶炼是五大湖农村地区气溶胶的人为来源。元素比率表明，五大湖气溶胶中的钠与氯的比率与海水中的相似。富集因子分析揭示了具有非地壳来源的元素，包括银、砷、溴、氯、铜、碘、铟、锑、硒、锡、钨和锌。
