Personal exposure to benzene of selected population groups, and impacts of traffic on commuters in Ho Chi Minh City were investigated. The study was carried out in June, July and November 2010. The preliminary data showed that on average, personal exposure to benzene for non-occupational people in Ho Chi Minh is ~18 μg/m(3) and most of the exposure is due to commuting. Benzene exposure during travelling by bus, taxi and motorcycle is, respectively, 22-30, 22-39 and 185-240 μg/m(3). Motorcycle-taxi drivers, petrol filling employees and street vendors suffer high daily exposures at 116, 52, 32 μg/m(3), respectively. Further measurements are needed for a better risk assessment and finding effective measures to reduce exposure.
本研究调查了胡志明市部分人群的个体苯暴露水平，以及交通对通勤者的影响。该研究于 2010 年 6 月、7 月和 11 月进行。初步数据显示，胡志明市非职业人群的平均个体苯暴露水平约为 18μg/m(3)，且大部分暴露来自通勤。乘坐公共汽车、出租车和摩托车通勤的苯暴露水平分别为 22-30μg/m(3)、22-39μg/m(3)和 185-240μg/m(3)。摩托车出租车司机、加油工和街头小贩的日平均暴露水平分别为 116μg/m(3)、52μg/m(3)和 32μg/m(3)，暴露水平较高。需要进一步的测量来进行更好的风险评估，并找到有效减少暴露的措施。
