在中国北方,有机气溶胶,硫酸盐和硝酸盐是重要的颗粒物组分。在雾霾天，硫酸盐主要由液相生成且具有低挥发性而硝酸盐主要由气相反应生成具有高挥发性; 利用无机盐的生成特点将有机和无机组分综合起来进行受体模型分析，可将将有机组分细分为更多的来源，进一步探讨其来源过程 （图一）。
中国5省份农村室内空气PM1.0和CO污染特征
室内空气污染 燃料 炉灶 PM1.0, CO
2014/6/12
室内空气污染对人体健康威胁逐渐加重，而我国农居室内空气中颗粒物和CO对农户危害较为突出，目前该领域全面和深入的研究鲜有报道. 2009年7月~2011年1月，调研了湖北、河北、辽宁、贵州和广东等5个省份共74户农村家庭，其中实时监测了58户家庭在不同燃料（生物质、蜂窝煤、液化气和沼气）和炉灶类型（开放式柴灶、传统灶、节柴灶）下，其室内PM1.0，CO，CO2和风速、温度等浓度和数据. 通过分析数据...
东莞市PM1中重金属元素的污染特征及来源解析
PM1 东莞 重金属 源解析
2014/2/17
采集了2011年8月—2012年7月间东莞市不同区域两点（A：生活区；B：工业区）的PM2.5~10、PM1~2.5和PM1样品，并用ICP-MS分析了颗粒物上Pb、Cu、Zn、As、Cd、V、Mn、Cr、Hg和Al等10种元素，重点研究了PM1中除Al外其它9种重金属元素的污染特征.分析结果显示，工业区B点PM1中的重金属污染明显较生活区A点严重，9种重金属元素在B点PM1中的浓度是A点的2.3...
