Industrial air pollution creates severe problems and evaluation of control scenarios rationally which can
be carried out using air quality models. In this study, an industrial region Chembur in Mumbai city was
selected to estimate air quality change for various control scenarios. Weather Research and Forecasting
(WRF) and AMS/EPA Regulatory Model (AERMOD) were used for this study. Since, the industries of
Chembur region were already existing and residential and commercial zones were pre-set in the domain,
so scenarios like increment of stack height and fuel change of industries can help to make better and
healthier air quality. Scenarios selected were the 10% (SH1), 25% (SH2) and 50% (SH3) increment of height
of stacks of industry and use of low emission fuel (F1 and F2) in the industries. Industrial air pollution
modelling was done for current scenario as well as proposed control scenarios. The reduction of air
quality level for each control scenario was calculated. Overall scenario SH3 as expected had more or less
maximum reduction at ground level concentration for various temporal cases for all pollutants. However,
it would cause more residence time of pollutants in atmosphere. Also this scenario was not based on
source emission reduction strategy. Scenario F1 considers fuel with lowest emission and source emission
reduction strategy. Therefore, scenario F1 seems to be the most preferred option for all pollutants among
all scenarios. This study can help in taking objective and rational decisions for control scenarios for
industrial sources.
