| 摘 要： | 采集某亚运场馆集中空调通风系统风管内积尘,并应用石墨炉原子吸收光谱法检测了积尘中重金属含量。检测结果分别为铅0.05—3.58mg/kg,镉0.01—0.80mg/kg,铜0.18—16.11mg/kg,锰0.07—7.98mg/kg和铬0.48—8.03mg/kg。各元素回收率在90.0%—113.3%之间。本方法简便、准确,为进一步评价空调系统的卫生状况和风管积尘对人体的影响提供了技术支持。

| Abstract: | The dust from the duct surface of heating-ventilating-air conditioning（HVAC） systems in the Asian Games venues was collected,and the contents of heavy metal in the dust were determined by graphite furnace atomic absorption spectrometry.The results were 0.05—3.58mg/kg for Pb,0.01—0.80mg/kg for Cd,0.18—16.11mg/kg for Cu,0.07—7.98mg/kg for Mn and 0.48—8.03mg/kg for Cr,respectively.Recovery for each element was between 90.0% and 113.3%.The method is accurate and easy,and that provides the technical support for further evaluation of sanitary condition of HVAC and the influence of duct surface dust on human health. |
