Assessment of nitrogen dioxide concentrations and main sources in a medium-sized city in Latin America using geographic information systems
Studying atmospheric nitrogen dioxide (NO2) concentrations in urban areas is crucial for assessing air quality and caring for the population’s health; however, the background of studies on this gas in medium-sized cities is scarce, highlighting a significant knowledge gap in the field, especially in Latin America. This study aims to assess the levels of NO2 concentration in a medium-sized city in Argentina using passive samplers over six months. The Geographic Information Systems (GIS) was employed to analyse the spatial distribution of gas concentration using the Inverse Distance Weighting (IDW) interpolation method. Additionally, potential emission sources were evaluated by applying exploratory regression analysis. The study found that atmospheric concentrations of NO2 generally exceeded the values established by the World Health Organization (WHO) of 10 µg/m3. The highest mean concentration (30.4 µg/m3) was determined near a national route and industrial areas. Correlation analysis between the NO2 concentration at each site and possible emission sources suggests that industries are the main sources of this gas.
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.
