Abstract

The industrial source complex model is widely used steady-state Gaussian plume model can be used to assess nonreactive pollutant concentrations from a wide variety of source types that are associated with an industrial source complex. The model provides different alternatives for the emissions from different sources including point, area and line sources. It is based on the Gaussian dispersion equations defining the horizontal and vertical distributions of the pollutants by turbulence. This model is the latest version of the regulatory model and assesses pollutant concentrations from wide variety of sources associated with an industrial complex. The study as well as modelling part has been carried out for the period of six months i.e. October’2014 to March’2015 in the study area. From the study it has been observed that the maximum resultant concentrations due to incremental ground level incremental concentrations were 67.54, 37.50 and 34.2 μg/m3 of particulate matter (PM), SO2 and NO2, respectively.
