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.
PM(10) 气溶胶样品于 2009 年 7 月至 2010 年 6 月在印度德古尔市收集，使用 Andersen 气溶胶采样器，并通过离子色谱法分析了八种水溶性离子，即 Na(+)、NH(4)(+)、K(+)、Mg(2+)、Ca(2+)、Cl(-)、NO(3)(-)和 SO(4)(2-)。PM(10) 的年平均浓度（253.5±99.4μg/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（60μg/m(3))的四倍。三种最丰富的离子是 SO(4)(2-)、NO(3)(-)和 NH(4)(+)，平均浓度分别为 8.88±4.81、5.63±2.22 和 5.18±1.76μg/m(3)，分别占分析的总水溶性离子的 27.1%、16.5%和 15.5%。所有二次离子（即 SO(4)(2-)、NO(3)(-)和 NH(4)(+)）的季节性变化相似，冬季浓度较高，季风期间浓度较低。方差极大旋转成分矩阵主成分分析确定了二次气溶胶、地壳再悬浮以及煤炭和生物质燃烧是印度德古尔市 PM(10)的共同来源。
