摘要

对二氧化氮和颗粒物的浓度进行了建模，以评估塔林市中心城市再生方案的健康效益，其中两条主要街道的交通量将减少，为活跃的通勤者创造一个更友好的空间。为了模拟空气质量，使用了25米网格分辨率的静止高斯羽流模型AEROPOL。该模型与该领域的一个固定空气质量监测站进行了验证。这些情景的健康效益是根据居民和日常访客的空气污染暴露变化，使用健康影响评估方法计算的。这项研究预测，每年减少市中心的废气（以NO2表示）和道路灰尘（以PM10表示）暴露将防止普通人群中多达0.29人过早死亡（−27%），日常游客中多达0.57人死亡（−3.6%），行人中多达0.18人死亡（–21.2%），公共交通使用者中多达0.03人死亡（-24.7%）。

Modelling the air quality for assessing the health benefits of urban regeneration: a case of Tallinn city Centre, Estonia

Concentrations of nitrogen dioxide and particulate matter were modelled to assess the health benefits of an urban regeneration scenario for the central part of Tallinn, where the traffic on two of the main streets will be reduced to create a more friendly space for active commuters. To model the air quality the stationary Gaussian plume model AEROPOL was used with a 25 m grid resolution. The model was validated against a stationary air quality monitoring station in the domain. The health benefits of the scenarios were calculated based on the changes in air pollution exposures for residents and daily visitors, using methods of health impact assessment. This research predicts that each year the reduction of exhaust (indicated by NO2) and road dust (indicated by PM10) exposure in the city centre would prevent up to 0.29 premature deaths (−27%) among the general population, 0.57 deaths (−3.6%) among daily visitors, 0.18 deaths (−21.2%) among pedestrians, and 0.03 deaths (−24.7%) among people public transport users.

期刊介绍： IJEP provides an international forum in the field of environment and pollution and addresses early and medium-term challenges involving scientific prediction, modelling and assessment. It focuses on ground-breaking research in the science of environmental pollution, at the early scientific stage. It is one of three key journals which together offer complete coverage of environmental issues: IJETM focuses on technical/engineering, policy and management solutions for environmental problems, and IJGEnvI focuses on future, longer-term environmental scenarios, ecological economics, climate change and biodiversity.
