摘要

摘要:
为研究伊犁河谷城市群不同城市不同粒径大气颗粒物的组分特征和来源，于2021年7月19—29日，在伊犁河谷城市群的伊宁市、伊宁县、察布查尔锡伯自治县（简称察县）和霍城县布设6个采样点采集大气PM_2.5和PM₁₀样品，对样品中的化学组分(无机元素、水溶性离子和碳组分)进行分析，并使用化学质量平衡模型对其来源进行解析。结果表明：研究期间伊犁河谷核心区城市群PM_2.5和PM₁₀浓度均处于较低水平，分别为（22.81±2.79）和（58.81±6.95）μg/m³；从空间分布来看，伊宁市和伊宁县的颗粒物浓度相对较高，霍城县和察县的浓度相对较低。化学组分质量重构结果表明，地壳元素是研究期间PM_2.5和PM₁₀的主要组分，占比分别为39.8%和54.1%；其次为有机物，占比分别为33.2%和19.8%；二次无机离子在PM_2.5和PM₁₀中也有一定占比，分别为20.2%和10.7%。源解析结果表明，PM_2.5主要来自二次颗粒物（29.1%）和扬尘源（28.3%）的贡献，工业源（16.1%）、机动车（10.5%）、燃煤源（9.3%）也均有一定贡献；PM₁₀中则以扬尘源的贡献最大（42.3%），远高于二次颗粒物（14.7%）、工业源（14.1%）、机动车（8.4%）和燃煤源（7.3%）。

Abstract:
To analyze the composition characteristics and sources of atmospheric particulate matter with different particle sizes in Ili Valley Urban Agglomeration, PM_2.5 and PM₁₀ samples were collected at six sampling sites in four cities/counties, including Yining City, Yining County, Qapqal Xibe Autonomous County and Huocheng County from July 19 to 29, 2021. The chemical components, including elements, ions and carbon components, of these samples were analyzed, and the chemical mass balance model was used to analyze their sources. The results showed that the concentrations of PM_2.5 and PM₁₀ in the urban agglomeration in Ili Valley core area were at low levels during the sampling period, which were (22.81±2.79) and (58.81±6.95) μg/m³, respectively. Among the four cities/counties, the concentrations in Yining City and Yining County were higher than those in Huocheng County and Qapqal Xibe Autonomous County. The results of chemical mass closure analysis showed that mineral dust was the main component of PM_2.5 and PM₁₀ during the study, accounting for 39.8% and 54.1%, respectively. Organic matter was the next, accounting for 33.2% and 19.8%, respectively. Secondary inorganic ions also accounted for 20.2% and 10.7% of PM_2.5 and PM₁₀, respectively. The result of sources apportionment by chemical mass balance model showed that PM_2.5 was mainly contributed by secondary particulate matter (29.1%), dust sources (28.3%), industrial sources (16.1%), motor vehicles (10.5%) and coal combustion sources (9.3%), and PM₁₀ by dust sources (42.3%), secondary particulate matter (14.7%), industrial sources (14.1%), motor vehicles (8.4%) and coal combustion sources (7.3%).
