| 摘 要： | 2004年4、7、8、11、12月采用微型捕集管-冷原子荧光光谱法对贵阳市一个居民区大气中的痕量颗粒态总汞(TPM)进行了测定。结果表明:TPM日均浓度范围是0.149~4.853 ng.m-3,平均值是1.091 ng.m-3,显著高于背景参考值1~86 pg.m-3;TPM浓度采暖期大于非采暖期,夜间通常大于白昼;TPM与大气气态总汞(TGM)可能具有同源性;燃煤、垃圾焚烧以及周边工厂排放的含尘烟气可能是居民区大气颗粒态汞的主要人为来源。

| Abstract: | ome measurement campaigns were carried out to determine trace total particulate mercury(TPM) in the atmosphere using a new miniaturized trap in April,July,August,November and December,2004.The TPM concentrations in the whole sampling period ranged from 0.149 to 4.853 ng·m-3 with an average of 1.091 ng·m-3,which is significantly compared to the background of 1‐86 pg·m-3.TPM in heating time was higher than that in non-heating time.The nighttime TPM concentrations were generally larger than those at daytime.It was possible that the major TPM emission source was the same as TGM.Coal combustion,waste incineration and industrial ash-laden gas were regarded as major anthropogenic sources of TPM in a residential area. |
