Effect of inversion on pollutant dispersion of the steel factory
Hormozgan Steel Complex (HOSCO) in IRAN has 4 stacks that are installed on the electric arc furnace and cause the release of pollutants. this study aimed to model the dispersion of emitted CO, NO2, and PM10 from stacks in HOSCO and identify the role of inversions in the dispersion of these pollutants. Pollutants emission rate were determined based on the collected data after measuring concentrations in the station (stacks) and across different distances from it for winter and summer. Hourly meteorological data from the on-site and Web GIS topography in the AERMOD was used to predicting of pollutants. The pollutants release pattern was simulated, and annual pollutant concentrations in average periods of 1–8 h and 24-hr were predicted using AERMOD. The results of Wind rose plot showed that the prevailing annually wind is SE. Inversions are of the radiative in the winter that its base is at a height of 50 m, but are of the subsidence in the summer that its base is at 500 m. Therefore, in the winter, the ambient is very polluted compared to the summer. The max of PM10, NO2, and CO in the 24, 1, and 8-hr were 25, 86, and 35 ug/m3 respectively, which accumulated on the slopes of the northwest cliffs of the site. But in winter, the core of maximum pollutants is shifted to the East. Therefore, it can be concluded that in winter, as pollutants ambient move to Bandar Abbas on the near of surface earth, and the risk of health is high.
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.
