摘 要: 为了解商场建筑内环境污染现状,分别对上海、广州、重庆等8个城市的16个商场内的甲醛和总挥发性有机物(total volatile organic compounds,TVOC)的浓度进行检测。分析表明,不同城市商场内空气中的甲醛、TVOC浓度存在一定差异,夏季室内污染物超标率均高于冬季,夏季TVOC浓度超标率高于甲醛、冬季无明显差异。调查结果显示,大多数城市商场内甲醛浓度低于国家标准规定的限值,但是对不同性别的员工仍存在致癌风险,尤其是武汉和天津商场员工的甲醛致癌风险较大。
关 键 词: 通风与空调工程;致癌风险;暴露水平;甲醛;总挥发性有机物

Abstract: In order to understand the status of environmental pollution in the mall buildings, formaldehyde and total volatile organic compounds (TVOC) concentrations were detected respectively in 16 shopping malls in 8 cities, Shanghai, Guangzhou and Chongqing, etc. The results show that there are some differences between the concentrations of formaldehyde and TVOC in the air of shopping malls in different cities. Indoor pollutants exceeding rate in summer is higher than that in winter. The concentration exceeding rate of TVOC is higher than that of formaldehyde, thus there’s no significant difference in winter. According to the survey results, formaldehyde concentrations of the majority of city malls are lower than the limit value specified by the state, but the staff of different genders have formaldehyde cancer risk, especially in Wuhan and Tianjin, where formaldehyde cancer risk is more higher.
Key words: ventilation and air conditioning engineering; cancer risk; exposure level; formaldehyde; total volatile organic compounds
