  • 摘要: 为了探讨承德市冬季大气细颗粒物中水溶性离子的污染特征及其来源，于2019年1月2—31日在承德市不同功能区设置4个采样点采集PM2.5样品共120个，对其中SO42-、NO3-、Cl-、NH4+、Na+、K+、Ca2+、F-和Mg2+等9种水溶性无机离子（WSIIs）进行分析.结果表明，SO42-、NO3--N、NH4+-N与Cl-为主要水溶性离子，铵盐主要以NH4NO3、NH4HSO4和NH4Cl的形式存在；各采样点WSIIs浓度特征为工业区（19.46±16.91）μg·m-3 > 典型区县（18.25±15.60）μg·m-3 > 混合区（18.03±19.08）μg·m-3 > 景区（15.05±13.30）μg·m-3，且离子浓度与相对湿度相关性显著；阴阳离子平衡分析显示承德市冬季PM2.5整体偏酸性，阳离子有一定的亏损；NO3--N/SO42-浓度的比值均小于1，表明以燃煤源为主的固定源贡献率大于移动源贡献率，通过主成分分析得到WSIIs的来源主要是燃煤、钢铁等工业生产、生物质燃烧、机动车尾气和土壤扬尘等.
    Abstract: On January 2nd to 31st, 2019,four sampling pointswere set up in Chengde City different functional areas, and 120 samples of PM2.5 were collected to investigate the chemical characteristics and sources of WSIIs(Water Soluble Inorganic Ions).The concentration, source and characteristics of nine WSIIs,including SO42-,NO3-, Cl-,NH4+, Na+, K+, Ca2+, F- and Mg2+ were analyzed. SO42-, NO3-, NH4+ and Cl- were the dominated water-soluble ions, these ions mainly existed as in the form of NH4NO3,NH4HSO4 and NH4Cl. The gradation of the WSIIs concentration were as followings: Industrial district(19.46±16.91) μg·m-3> Typical counties(18.25±15.60) μg·m-3 > Mixed Zone(18.03±19.08) μg·m-3 > Scenic area (15.05±13.30) μg·m-3, and the ion concentration was significantly correlated with the relative humidity.The analysis based on charge balance demonstrated that the aerosol in Chengde was overall acidic, and cation had a certain loss. The concentration ratio of NO3-/SO42- was less than one indicated that the contribution rate of stationary sources (such as coal) was greater than the mobile sources. Principal component analysis showed that the main sources of WSIIs included coal combustion, industrial production, biomass burning, vehicle exhaust emissions and soil dust.

摘要: 为了探讨承德市冬季大气细颗粒物中水溶性离子的污染特征及其来源，于2019年1月2—31日在承德市不同功能区设置4个采样点采集PM2.5样品共120个，对其中SO42-、NO3-、Cl-、NH4+、Na+、K+、Ca2+、F-和Mg2+等9种水溶性无机离子（WSIIs）进行分析.结果表明，SO42-、NO3--N、NH4+-N与Cl-为主要水溶性离子，铵盐主要以NH4NO3、NH4HSO4和NH4Cl的形式存在；各采样点WSIIs浓度特征为工业区（19.46±16.91）μg·m-3 > 典型区县（18.25±15.60）μg·m-3 > 混合区（18.03±19.08）μg·m-3 > 景区（15.05±13.30）μg·m-3，且离子浓度与相对湿度相关性显著；阴阳离子平衡分析显示承德市冬季PM2.5整体偏酸性，阳离子有一定的亏损；NO3--N/SO42-浓度的比值均小于1，表明以燃煤源为主的固定源贡献率大于移动源贡献率，通过主成分分析得到WSIIs的来源主要是燃煤、钢铁等工业生产、生物质燃烧、机动车尾气和土壤扬尘等.
