摘要
利用分光光度法、溶剂解吸-气相色谱法对天津地区某大型超市和某教学楼的空气品质进行检测,同时采用呼吸暴露的评价方法分析这2个公共场所内工作人员的健康风险.结果表明:超市洗涤用品区和熟食区空气中甲醛的质量浓度明显高于其他售货区的质量浓度.苯和甲苯的最高质量浓度均出现在鞋区,最低质量浓度则出现在家电区.教学楼内空气中苯质量浓度为3.74～13.0μg/m3,甲苯质量浓度不高于6.34μg/m3.超市空气中的苯对男性和女性工作人员的致癌风险分别为1.32×10-4和9.23×10-5,大学教室内男教师和女教师的苯致癌风险接近美国EPA制定的人体致癌风险值1×10-6.
Indoor air quality in a large supermarket and a classroom building in Tianjin was investigated through the spectrophotometric method and solvent desorption-gas chromatography.Health risks of staff in the two public places were assessed through the inhalation exposure method.In the supermarket,the concentrations of formaldehyde in the washing products and cooked food areas are obviously higher than those in other areas,and the maximum concentrations of benzene and toluene simultaneously appear in the shoes area,whereas their minimum values occur in the household appliances area.In the classroom building,the concentrations of benzene ranges from 3.74 to 13.0 μg/m3,whereas the levels of toluene are not more than 6.34 μg/m3.Lifetime cancer risks of exposure to benzene for male and female staff in the supermarket are 1.32×10-4 and 9.23×10-5,respectively,whereas those for male and female teachers in the classrooms are close to 1×10-6.
