新装修办公楼室内苯系物污染变化及健康风险

为了了解新装修办公楼室内空气苯系物污染情况及其对人们致癌风险评价,采用气相色谱法(TD-GC),按照新装修后3个月和6个月两个时段的办公楼室内空气中苯系物的平均浓度进行了检测。结果为:两个时段办公楼室内的苯系物的平均浓度均低于国家规定的标准值,办公楼室内空气中的苯对人们的致癌风险为5.45×10^-7~6.49×10^-7。建议新装修办公楼通风换气放置半年以上再入住办公。

In order to understand the indoor air benzene series pollution in newly decorated office buildings and its carcinogenic risk assessment, thermal desorption-gas chromatography (TD-GC) was used to detect the average concentrations of benzene series in the indoor air of office buildings 3 and 6 months after newly decorated. The results showed that the average concentration of benzene in the indoor air of the office building was lower than the national standard value, and the carcinogenic risk of benzene in the indoor air of the office building was 5.45×10^-7~6.49×10^-7. It is suggested that the newly decorated office building should be ventilated and leave unused for more than half a year.
