中文摘要	为了解中国极干旱区域和田市城区大气PM_(2.5)的组成特征及污染水平,于2014年112月采集和田市城区大气PM_(2.5)样品,并用气相色谱-质谱联用仪(GC-MS)、离子色谱仪(IC)、电感耦合等离子体质谱仪(ICP-MS)及元素分析仪分析其中PAHs (多环芳烃)、金属元素、水溶性无机离子、OC(有机碳)和EC(元素碳)等化学组分.结果表明,采样期间和田市城区大气PM_(2.5)质量浓度年均值为(770.11568.01)mug/m~3,呈夏季最高、冬季最低趋势;金属元素、水溶性无机离子、OC、EC、Sigma_(16)PAHs(总多环芳烃)分别占PM_(2.5)质量浓度的15.292%、9.789%、4.246%、0.331%、0.015%.利用PMF(正交矩阵因子分解法)分别对PM_(2.5)中PAHs和金属元素、水溶性无机离子、OC、EC进行来源解析表明,PAHs主要来源为煤和汽油燃烧排放(13.91%)、生物质燃烧(33.98%)、天然气燃烧(52.11%) ;金属元素、水溶性无机离子、OC、EC的主要来源为土壤尘(56.49%)、油类燃烧(25.49%)、机动车排放(10.09%)、燃煤及生物质燃烧(7.93%) .研究显示,采样期间沙尘对和田市城区大气PM_(2.5)组成影响较大,是该地区大气污染来源的主要因素.
英文摘要	In order to understand the component characteristics and contamination situation of atmospheric PM_(2.5) in the urban area of Hotan,which was the extreme arid area in China,PM_(2.5) samples were collected periodically from January to December in 2014. The seasonal distribution of the mass concentration of polycyclic aromatic hydrocarbons (PAHs),metal elements,water-soluble inorganic ions,organic carbon (OC) and elemental carbon (EC) were analyzed by chromatography-mass spectrometer,ion chromatographer (IC), inductively coupled plasma mass spectrometry,and elemental analyzer,respectively. The results showed that the annual average mass concentration of PM_(2.5) was (770.11568.01)mug/m~3 during the sampling period,with the highest in summer and the lowest in winter. The total mass of metal elements,water-soluble ions,OC,EC and PAHs accounted for 15.292%,9.789%,4.246%,0.331% and 0.015% of PM_(2.5) ,respectively. Subsequently,a positive matrix factorization (PMF) was exploited to analyze the sources of the components in PM_(2.5) . The PAHs mainly stemmed from coal/gasoline emissions (13.91%),biomass combustion (33.98%) and natural gas combustion (52.11%). PMF also identified that dust (56.49%),oil burning (25.49%),motor vehicle emissions (10.09%),coal burning and biomass combustion (7.93%) were the main sources of the other components of PM_(2.5) . The effect of sandstorm on the composition of PM_(2.5) was remarkable. The sandstorm was considered to be the major factor for the local air pollution.
