| Description |
Contribution of pollution from different types of sources in Jamshedpur, the steel city of India, has been estimated in
winter 1993 using two approaches in order to delineate and prioritize air quality management strategies for the
development of region in an environmental friendly manner. The first approach mainly aims at preparation of a
comprehensive emission inventory and estimation of spatial distribution of pollution loads in terms of SO2 and NO2
from different types of industrial, domestic and vehicular sources in the region. The results indicate that industrial
sources account for 77% and 68% of the total emissions of SO2 and NO2, respectively, in the region, whereas vehicular
emissions contributed to about 28% of the total NO2 emissions. In the second approach, contribution of these sources
to ambient air quality levels to which the people are exposed to, was assessed through air pollution dispersion
modelling. Ambient concentration levels of SO2 and NO2 have been predicted in winter season using the ISCST3
model. The analysis indicates that emissions from industrial sources are responsible for more than 50% of the total SO2
and NO2 concentration levels. Vehicular activities contributed to about 40% of NO2 pollution and domestic fuel
combustion contributed to about 38% of SO2 pollution. Predicted 24-h concentrations were compared with measured
concentrations at 11 ambient air monitoring stations and good agreement was noted between the two values. In-depth
zone-wise analysis of the above indicates that for effective air quality management, industrial source emissions should
be given highest priority, followed by vehicular and domestic sources in Jamshedpur region.
