中国成年男子大气中元素吸入量研究

Elemental Daily Inhalation of Chinese Adult Men

目的获得中国成年男子空气中46种元素日吸入量。方法在我国4个不同膳食类型地区连续3日采集大气中PM10样品,预处理后,采用ICP-MS,ICP-AES等仪器测定其中46种元素浓度。结合人体呼吸动力学计算统计各元素每日吸入量取中位数作为全国代表值。结果得到了中国成年男子空气中46种元素日吸入量。结论获得我国成年男子大气中46种元素日吸入量,为补全我国参考人相应参数参考值和某些重要生物动力学参数提供探索性依据。

Objective To obtain 46 elementsl of daily inhalation of Chinese adult men.Methods Inhalable particle samples in air were collected in 3 days runnings in 4 areas with different dietary types in China.The concentrations of 46 elements in these samples were analyzed by ICP-MS,ICP-AES after pretreatment with the human dynamics.The median of results were calculated as the representative ualues.Results The data of 46 elemental of daily inhalation of Chinese adult men were obtained.Conclusions The research provide exploratory basis for developing reference values of Chinese Reference Men and some important biokinetics parameters.
