摘　　要：针对空气中的重金属污染-汞,既要强调室外汞污染排放的监测,也要重视室内空气中的颗粒态汞污染;在各类化学实验室对汞有着较多接触下,为保障人员安全性,需要了解颗粒态汞的污染特征。为此,本文借助湿式消解法提取室内空气中的可吸入颗粒物,应用原子荧光光谱法测定颗粒态汞浓度,并与相关卫生、环保标准进行汞浓度对比,明确颗粒态汞的污染特征,以期在判断化学实验室空气的汞污染程度后,采用通风等手段降低颗粒态汞的影响,保障人员安全性。In response to heavy metal pollution in the air-mercury,it is necessary to emphasize the monitoring of outdoor mercury pollution emissions and also pay attention to particulate mercury pollution in indoor air.In various chemical laboratories where there is frequent exposure to mercury,it is necessary to understand the pollution characteristics of particulate mercury in order to ensure personnel safety.Therefore,this article uses the wet digestion method to extract inhalable particulate matter from indoor air,applies atomic fluorescence spectroscopy to measure the concentration of particulate mercury,and compares the mercury concentration with relevant health and environmental standards to clarify the pollution characteristics of particulate mercury.The aim is to reduce the impact of particulate mercury and ensure personnel safety by using ventilation and other means after determining the degree of mercury pollution in the air of the chemical laboratory.
