PM(10) aerosol samples were collected in Durg City, India from July 2009 to June 2010 using an Andersen aerosol sampler and analyzed for eight water-soluble ionic species, namely, Na(+), NH(4) (+), K(+), Mg(2+), Ca(2+), Cl(-), NO(3) (-) and SO(4) (2-) by ion chromatography. The annual average concentration of PM(10) (253.5 ± 99.4 μg/m(3)) was four times higher than the Indian National Ambient Air Quality Standard of 60 μg/m(3) prescribed by the Central Pollution Control Board, India. The three most abundant ions were SO(4) (2-), NO(3) (-), and NH(4) (+), with average concentrations of 8.88 ± 4.81, 5.63 ± 2.22, and 5.18 ± 1.76 μg/m(3), respectively, and in turn accounting for 27.1 %, 16.5 %, and 15.5 % of the total water-soluble ions analyzed. Seasonal variation was similar for all secondary ions i.e., SO(4) (2-), NO(3) (-), and NH(4) (+), with high concentrations during winter and low concentrations during monsoon. Varimax Rotated Component Matrix principal component analysis identified secondary aerosols, crustal resuspension, and coal and biomass burning as common sources of PM(10) in Durg City, India.

使用Andersen气溶胶采样器从2009年7月到2010年6月在印度杜尔格市收集了PM(10) 气溶胶样品,并分析了八种水溶性离子物种,即Na (),NH(4) (),K (),Mg(2),离子色谱法测定Ca(2 +) 、Cl(-) 、NO(3) (-) 和SO(4) (2-)。PM(10) 的年平均浓度 (253.5 ± 99.4 μ g/m(3)) 是印度中央污染控制委员会规定的印度国家环境空气质量标准60 μ g/m(3) 的四倍。三种含量最高的离子分别为SO(4) (2-) 、NO(3) (-) 和NH(4) (+),平均浓度分别为8.88 ± 4.81、5.63 ± 2.22、5.18 ± 1.76 μ g/m(3),并依次占所分析的总水溶性离子的27.1% 、16.5% 和15.5%。所有次级离子的季节变化相似,即SO(4) (2-),NO(3) (-) 和NH(4) (),冬季浓度高,季风浓度低。Varimax旋转成分矩阵主成分分析确定了二次气溶胶,地壳重悬以及煤炭和生物质燃烧是印度杜尔格市PM(10) 的常见来源。
