Ambient concentrations of organic carbon (OC), elemental carbon (EC) and water soluble inorganic ionic components (WSIC) of PM10 were studied at Giridih, Jharkhand, a sub-urban site near the Indo Gangatic Plain (IGP) of India during two consecutive winter seasons (November 2011–February 2012 and November 2012–February 2013). The abundance of carbonaceous and water soluble inorganic species of PM10 was recorded at the study site of Giridih. During winter 2011–12, the average concentrations of PM10, OC, EC and WSIC were 180.2 ± 46.4; 37.2 ± 6.2; 15.2 ± 5.4 and 18.0 ± 5.1 μg m−3, respectively. Similar concentrations of PM10, OC, EC and WSIC were also recorded during winter 2012–13. In the present case, a positive linear trend is observed between OC and EC at sampling site of Giridih indicates the coal burning, as well as dispersed coal powder and vehicular emissions may be the source of carbonaceous aerosols. The principal components analysis (PCA) also identifies the contribution of coal burning + soil dust, vehicular emissions + biomass burning and seconday aerosol to PM10 mass concentration at the study site. Backward trajectoy and potential source contributing function (PSCF) analysis indicated that the aerosols being transported to Giridih from upwind IGP (Punjab, Haryana, Uttar Pradesh and Bihar) and surrounding region.

贾坎德邦吉里迪（印度）冬季 PM10 中的碳质和无机物种

在印度恒河平原 (IGP) 附近的郊区吉里迪 (Giridih) 连续两次研究了 PM10 的有机碳 (OC)、元素碳 (EC) 和水溶性无机离子成分 (WSIC) 的环境浓度冬季（2011 年 11 月至 2012 年 2 月和 2012 年 11 月至 2013 年 2 月）。在 Giridih 的研究地点记录了 PM10 的碳质和水溶性无机物种的丰度。2011-12冬季，PM10、OC、EC和WSIC的平均浓度为180.2±46.4；37.2±6.2；分别为 15.2 ± 5.4 和 18.0 ± 5.1 μg m-3。2012-13 年冬季也记录到类似的 PM10、OC、EC 和 WSIC 浓度。在目前的情况下，在 Giridih 采样点观察到 OC 和 EC 之间的正线性趋势表明燃煤，以及分散的煤粉和车辆排放物可能是含碳气溶胶的来源。主成分分析 (PCA) 还确定了燃煤 + 土壤粉尘、车辆排放 + 生物质燃烧和二次气溶胶对研究地点 PM10 质量浓度的贡献。后向轨迹和潜在源贡献函数（PSCF）分析表明，气溶胶从上风 IGP（旁遮普邦、哈里亚纳邦、北方邦和比哈尔邦）和周边地区输送到 Giridih。
