【摘要】 采用分级采样装置 ,于冬夏两季采集呼市三个不同功能区不同粒径空气颗粒物中的汞进行分析 ,结果表明 :呼市空气颗粒物中的汞含量冬季明显高于夏季 ;冬季空气颗粒物中的汞含量为居民区 >交通区 >对照区 ,夏季为交通区 >居民区 >对照区 ;空气中汞主要富集在可吸入粒子中。更多还原

【Abstract】 Adopting the classification sampling equipments,the Hg of different diameters particles collected from three different functional areas in summer and winter in Huhhot were analyzed.The results showed that the Hg contents of air articles in winter were more than that in summer,in winter,the Hg contents of air particles showed the following decreasing sequence:residential area,traffic area and comparative area,in summer,appeared as the following decreasing sequence:traffic area,residential are and comparative area;the Hg in air mainly concentrated in absorptive particles.更多还原
