| 摘 要： | 用镀金细砂填充的石英采样管在采暖期的非采暖期于北京地区七个采样点收集空气中的气态汞，用二步汞齐化原子吸收法测定其浓度并与实时分析结果进行比较，两种方法的结果都表明，采暖期北京地区大气中汞的浓度低于非采暖期大气中汞的浓度，对于除燃煤以外汞的来源尚需进一步研究。

| Abstract: | Gaseous mercury from atmospheric environment was collected on gold coated sand quartz tubes at seven stations in Beijing area during heating time and unheating time. The concentrations of mercury were determined by using two stage gold amalgamation and atomic absorption mercury analyser. The comparison with near-real-time analysis was made. The data from two methods show that the mercury concentrations measured during heating time were lower than those measured during unheating time.The further research on other sources of mercury besides coal combustion in Beijing area will be needed. |
