摘　　要： 通过对北京市某地下车库内苯,甲苯,一氧化碳(CO),二氧化氮(NO2)和二氧化硫(SO2)五种污染物的现场测试和对附近人员的问卷调查发现,车库中苯和甲苯浓度超标,最高浓度分别为4.82mg/m3和15.50mg/m3;CO、NO2和SO2浓度相对较低,没有超过相关标准浓度,但仍高于周围环境中污染物浓度。车库内和排风口周围人群普遍受到影响,不满意率达100%,其中受影响最大的为车库内工作人员。受影响人群普遍感到存在有较强烈的异味,并伴随着咽喉肿痛、刺眼/流泪、咳嗽等症状。 The concentrations of benzene, toluene, CO, NO2 and SO2 were measured in a residential underground car park of Beijing. Combined with the questionnaires, we found that the underground car park was severely polluted by the traffic exhaust, especially benzene and toluene, of which concentrations were 4.82 mg/m^3 and 15.50 mg/m^3 in the high peak respectively. Concentrations of CO, NO2 and SO2 were relatively low, but were also much higher than the ambient air. People nearby were all influenced especially the staff of the underground car park, and all people sense the presence of some odour and have the symptoms of throat pain, eye stimulation, tears and cough.
