中文摘要：

在北京市近郊和远郊区采集大气中可吸入颗粒物样品,分析其汞的浓度水平.结果表明,近郊大气可吸入颗粒物中汞的浓度高于远郊区,分别为1.28±1.30ng·m^-3和0.79±0.68ng·m^-3,而且冬、春两季的浓度明显高于夏、秋两季.可吸入颗粒物中的汞主要分布在细粒子中,且细粒子富集汞的能力较粗粒子强.

英文摘要：

Mercury concentrations in airborne inhalable particulate matters were measured at the urban and suburban sites in Beijing. The average concentrations of mercury in inhalable particles were 1.28 ±1.30 ng·m^-3with a range of 0. 21-5.76ng·m^-3 at the suburban site and 0. 79 ±0. 68ng·m^-3 with a range of 0. 11-3. 12ng·m^-3 at the urban site. The variations of mercury concentration at two sites were comparable, and the concentrations in winter and spring were higher than those in summer and autumn seasons. Mercury in fine particles was the main part of the total in PM10.
