The statistical basis for factor analysis is briefly discussed. A method combining common factor analysis with orthogonal transformation has been proposed and discussed in detail. The method has been tested with a data set consisted of 16 elemental concen trations in 40 samples collected at the Beijing meteorological tower, March 1980. 7 sources, soil+coal fly ash, sulfate, cement and lime dust, oil, plant burning, motor, and marine aerosol, corresponding to 7 factors have been identified and the source...

本文简要介绍了因子分析法的统计学基础.提出了一种因子分析与经验正交变换相结合的分析方法.用这种方法研究了1980年3月在北京北郊用条式滤膜采样仪采样,用质子荧光法进行元素分析所得到的16种元素,40个样品的资料.得到了土壤尘加燃煤烟尘、汽车废气、石灰水泥粉尘、硫酸盐、草木燃烧、石油化工和海盐粒子等7种气溶胶来源对北京北郊大气气溶胶的相对贡献以及这些源的元素成分廓线.

INAA and PIXE techniques were used to measure 45 element contents in 150 air-filter samples collected at 10 sites in Beijing-Tianjin area during the winter of 1983 and the summer of 1984. It was found that the toxic elements were enriched in fine particles with diameter less than 2μm. Seven sources attributing the dust pollution were identified as coal burning, oil burning, soil dust, marine aerosol, motor vehicle emission, limestone dust, and industrial refuse, of which the soil dust and the emission...

Seven sources attributing the dust pollution were identified as coal burning, oil burning, soil dust, marine aerosol, motor vehicle emission, limestone dust, and industrial refuse, of which the soil dust and the emission from coal-combustion were the main contributors.

采用中子活化分析及质子激发X荧光分析测定了160个样品中的45种元素含量,研究了不同粒径颗粒物中元素浓度的分布规律,得知对人体有害的元素主要富集在粒径小于2μm的细颗粒中。根据测定的元素浓度特征,可分成七个主要污染来源,即煤、土壤、石油、汽车尾气、建筑材料、海盐及冶金工业。化学元素平衡计算结果表明,天津地区七个污染源中,尘土和燃煤对大气颗粒物的贡献最大。

31 marine aerosol samples were collected during a period of 1984, 11-1985,3. The contents of sulfate and sodium in the samples were determined. The results indicated that the concentration of non-sea-salt sulfate (NSS SO42-) in the marine aerosol clearly decreases from the North Pacific to the South Pacific. A large portion of the NSS sulfate in the North Pacific atmosphere are from the continental pollution sources through longdistance transport and the relatively low concentration of NSS sulfate in marine...

31 marine aerosol samples were collected during a period of 1984, 11-1985,3. The contents of sulfate and sodium in the samples were determined. The results indicated that the concentration of non-sea-salt sulfate (NSS SO42-) in the marine aerosol clearly decreases from the North Pacific to the South Pacific. A large portion of the NSS sulfate in the North Pacific atmosphere are from the continental pollution sources through longdistance transport and the relatively low concentration of NSS sulfate in marine aerosols over the South Pacific and the Antarctic Peninsula waters may be attributed to an oceanic sulfate source due to marine biological processes. The sea to air flux of sulfur was calculated as a value f 0.065 gS/m2-a in the Antarctic Peninsula waters.

我国首次南极考察(1984年11月—1985年3月)在太平洋和南极半岛周围海域收集了31个海洋气溶胶样品。采用离子色谱法分析气溶胶中硫酸盐、火焰原子吸收法分析钠离子,结果表明,太平洋海洋气溶胶中非海盐源硫酸盐含量自北纬向南纬明显降低。在北太平洋主要是由于陆源污染源的硫酸盐在风系作用下经长距离传输而进入海洋上空;而在南太平洋,特别是南极半岛海域大气中非海盐源硫酸盐,可能主要来自海洋生物活动的产物。利用通量计算模式,估算了南极半岛海域生物源输入大气的硫通量为0.065gS/m~2·a。
