This study proposes to assess the potential health benefits of LEZs for the population of the Paris region by taking into account individual levels of exposure to air pollution during travel and activities during the day. Dynamic maps of NO₂ concentration, a household travel survey and a road traffic model are used to assess the population exposed to air exceeding 40 µg/m³ of NO₂. The impact of LEZ implementation in the Paris region would be smallest for those populations that are most sensitive to pollution problems, the youngest and oldest. The wealthiest would be the big winners from the LEZ, but were also the most exposed. According to scenarios, between 13 and 43% of residents who were exposed to high NO₂ concentrations outside the LEZ perimeter fell below the critical threshold of 40 µg/m³.

本研究建议通过考虑个人在旅行和白天活动期间接触空气污染的水平，评估低排放区对巴黎地区人口的潜在健康益处。NO ₂浓度动态图、家庭旅行调查和道路交通模型用于评估暴露于NO ₂超过40 µg/m ³的空气中的人群。对于那些对污染问题最敏感、最年轻和最年长的人群，LEZ 在巴黎地区实施的影响最小。最富有的人将是来自 LEZ 的大赢家，但也是最暴露的。根据情景，13% 至 43% 的居民暴露于高 NO ₂LEZ 周边以外的浓度低于临界阈值 40 µg/m ³。
