| 摘 要： | 2010年5月12日-2010年6月19日,采用俄罗斯生产的Lumex RA-915AM和加拿大生产的Tekran 2537A对贵阳市城区的大气气态总汞进行了连续高时间分辨率的观测.结果表明:尽管2种仪器采用的方法原理不同,但其测量结果在总体含量分布、变化规律上均具有很好的一致性,说明二者均能准确测定大气气态总汞含量.贵阳市大气气态总汞含量显著高于全球背景区浓度,同时也高于欧美同类型地区的观测结果.污染源识别表明,贵阳市居民生活活动的面源汞释放是影响该地区大气气态总汞分布的一个重要因素;此外,位于贵阳市东部的大型工矿企业也是该地区大气汞的重要来源.

| Abstract: | From May 12 to June 19,2010,a high-time resolution observation on the atmospheric total gaseous mercury(TGM) concentration in an urban area of Guiyang was continuously conducted by using Lumex RA-915AM(made in Russia) and Tekran 2537A(made in Canada).Though the two sampling instruments have distinct operation principles,the overall characteristics and temporal distribution patterns of measured atmospheric TGM concentration were quite consistent,indicating that both of the instruments could accurately measur... |
