Source contributions to PM10 and sulfate aerosol at McMurdo Station, Antarctica during the austral summers of 1995-1996 and 1996-1997 were estimated using Chemical Mass Balance (CMB) receptor modeling. The average PM10 (particles with aerodynamic diameters less than 10 microm) concentration at Hut Point, located less than 1 km downwind of downtown McMurdo, was 3.4 microg/m3. Emissions profiles were determined for potentially important aerosol source types in McMurdo: exposed soil, power generation, space heating, and surface vehicles. Soil dust, sea salt, combustion emissions, sulfates, marine biogenic emissions as methanesulfonate, and nitrates contributed 57%, 15%, 14%, 10%, 3%, and 1%, respectively, of average estimated PM10 at Hut Point (3.2 microg/m3). Soil dust, sea salt, and combustion sources contributed 12%, 8%, and 20%, respectively, of the average PM10 sulfate concentration of 0.46 microg/m3. Marine biogenic sources contributed 0.17 microg/m3 (37%). The remaining sulfate is thought to have come from emissions from Mt. Erebus or hemispheric pollution sources.
利用化学质量平衡（CMB）受体模型估算了1995 - 1996年和1996 - 1997年南半球夏季期间，南极麦克默多站PM10和硫酸盐气溶胶的源贡献。位于麦克默多市中心下风不到1公里处的胡特角的PM10（空气动力学直径小于10微米的颗粒）平均浓度为3.4微克/立方米。确定了麦克默多潜在重要气溶胶源类型的排放特征：裸露土壤、发电、空间供暖和地面车辆。土壤灰尘、海盐、燃烧排放、硫酸盐、作为甲磺酸盐的海洋生物源排放和硝酸盐分别占胡特角平均估算PM10（3.2微克/立方米）的57%、15%、14%、10%、3%和1%。土壤灰尘、海盐和燃烧源分别占平均PM10硫酸盐浓度0.46微克/立方米的12%、8%和20%。海洋生物源贡献了0.17微克/立方米（37%）。其余的硫酸盐被认为来自埃里伯斯山的排放或半球污染源。
