Health benefits of traffic-related PM2.5 and CO reduction—a case study of Tianjin, China, from 2015 to 2019
Traffic emissions are a major source of ambient air pollution, and exposure to these emissions has been linked to numerous adverse health effects. Our study investigated the reduction of traffic emissions in downtown Tianjin, China, and assessed its health benefits. Based on the vehicle emission inventory, The Atmospheric Dispersion Modelling System (ADMS) was adopted for simulating the dispersion of traffic-related air pollutants including primary fine particulate matter (PM2.5), and carbon monoxide (CO). The Benefits Mapping and Analysis Program (BenMAP) was then used to quantify the benefits of emission reductions with respect to cardiovascular disease and respiratory disease. We found a downward trend in PM2.5 and CO concentrations from 2015 to 2019 (PM2.5: 17.8 to 10.5μg/m3, CO: 2.3 to 1.3mg/m3). Furthermore, in line with the reduction of average annual PM2.5 and CO attributable to traffic emissions during 2016–2019 compared with 2015, the accumulative deaths from the two diseases mentioned above in these years decreased by 156 and 961 respectively. Our study constructs an integrated framework combining emission inventories, air quality modeling, and population health benefits, which can be used for further health effects of related air quality improvement.
期刊介绍：
Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health.
It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes.
International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals.
Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements.
This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
