Air Quality at Public Transportation Stations/Stops: Contribution of Light Rail Transit to Reduce Air Pollution
Air pollution from cars, vans and other different motor cars had observed in higher concentrations at public transportation stations. Now a day’s air pollutants from public transportation, industry, cooking from firewood and dust production alongside main roads in Addis Ababa is increasing and affecting human health. Individuals who live and work close to streets seem to have an expanded occurrence and openness to medical issues related to transportation air contamination. Appropriately, the Addis Ababa Light Rail Transit was the main current mass transit framework in Ethiopia just as in Sub Saharan Africa launched in 2015. Thus, this study aimed to know the air quality at LRT, bus, taxi and mixed stations through an air tracking device, and health effect at sampled public transportation stations. Air quality data include particulate matter (PM2.5, PM10), air quality index (AQI), carbon dioxide (CO2), humidity and temperature with a half-hour observation through Air-Visual pro for every 24 purposively sampled stations from North to South LRT line. The average measured air quality indicated that higher than 35 μg/m3 PM2.5 and 100 AQI, which is unhealthy. Regards to this, 30 persons were questioned at all stations. Seven hundred twenty (720) persons in total to know the health effect of those living/working in and around the stations. The findings indicated that out of 720 respondents, 324 (45%) have experienced to air quality-related diseases residing and working proximity to the stations. These suggested that the aged vehicles, land-use, dust and design of bus-stop shelter for waiting passengers have increased exposure to vehicles air pollution. Consequently, peoples are exposing to air quality-related respiratory diseases particularly unhealthy for sensitive groups.
期刊介绍:
ASE is an international journal that publishes high-quality papers, communications, and discussion that advance aerosol science and engineering. Acceptable article forms include original research papers, review articles, letters, commentaries, news and views, research highlights, editorials, correspondence, and new-direction columns. ASE emphasizes the application of aerosol technology to both environmental and technical issues, and it provides a platform not only for basic research but also for industrial interests. We encourage scientists and researchers to submit papers that will advance our knowledge of aerosols and highlight new approaches for aerosol studies and new technologies for pollution control. ASE promotes cutting-edge studies of aerosol science and state-of-art instrumentation, but it is not limited to academic topics and instead aims to bridge the gap between basic science and industrial applications. ASE accepts papers covering a broad range of aerosol-related topics, including aerosol physical and chemical properties, composition, formation, transport and deposition, numerical simulation of air pollution incidents, chemical processes in the atmosphere, aerosol control technologies and industrial applications. In addition, ASE welcomes papers involving new and advanced methods and technologies that focus on aerosol pollution, sampling and analysis, including the invention and development of instrumentation, nanoparticle formation, nano technology, indoor and outdoor air quality monitoring, air pollution control, and air pollution remediation and feasibility assessments.
