Abstract

This study aims to obtain a reliable inventory of the emission rates of the principal air pollutants including PM, SO₂, NO_x and CO in Kocaeli, Turkey. In the first stage, the pollutant sources classified as point, area and line sources are determined in the area. Then the annual emission rates of the pollutants released from these sources are estimated by the emission factors given by USEPA and CORINAIR. Results show that the annual emission rates for PM, SO₂, NO_x and CO are 2195 tons, 5342 tons, 14632 tons and 23095 tons, respectively. On the other hand, the pollutant group with the highest contribution to total emission rate is determined as the point sources for NO_x, which is responsible for 73% of total NO_x emission, while it is the area sources for PM, SO₂ and CO with the contribution percentages of 75, 76 and 69, respectively.
