飞机座舱挥发性有机化合物健康风险评价研究

Health risk assessment of volatile organic compounds in aircraft cabin

选取苯、甲苯、乙苯和二甲苯(BTEX)为挥发性有机化合物的代表,采用美国环保署的致癌风险评价和非致癌风险评价模型,对BTEX在飞机座舱中对乘客可能造成的致癌风险和非致癌风险进行了计算。浓度数据来自于对14架航班飞机座舱的实际测试,暴露参数主要来源于针对中国人群的相关文献。针对不同人群(儿童、少年、成年和老人)的计算结果表明,所有人群的致癌风险和非致癌风险均低于美国环保署的限值。

Selects benzene,toluene,ethylbenzene,xylene （BTEX）as representative of volatile organic compounds,adopts the assessment models for carcinogenic risk and non-carcinogenic risk proposed by United States Environment Protection Agency （US EPA）,and calculates the carcinogenic risk and the non-carcinogenic risk to passengers caused by BTEX in aircraft cabins.The concentrations of BTEX are from the field measurement data in 14 in-operation flights,and the exposure parameters are from the literatures about Chinese population.The results for different people （children,juvenile,adult and the aged）show that both the carcinogenic risk and the non-carcinogenic risk are lower than the limit value given by US EPA.
