Assessment of contribution of SO2 and NO2 from different sources in Jamshedpur region, India

摘要: Abstract Contribution of pollution from different types sources in Jamshedpur, the steel city India, has been estimated winter 1993 using two approaches order to delineate and prioritize air quality management strategies for development region an environmental friendly manner. The first approach mainly aims at preparation a comprehensive emission inventory estimation spatial distribution loads terms SO 2 NO industrial, domestic vehicular region. results indicate that industrial account 77% 68% total emissions , respectively, region, whereas contributed about 28% emissions. In second approach, contribution these ambient levels which people are exposed to, was assessed through dispersion modelling. Ambient concentration have predicted season ISCST3 model. analysis indicates responsible more than 50% levels. Vehicular activities 40% fuel combustion 38% pollution. Predicted 24-h concentrations were compared with measured 11 monitoring stations good agreement noted between values. In-depth zone-wise above effective management, source should be given highest priority, followed by Jamshedpur
