A new approach for the estimation of immission loads under steady state conditions

Air quality management takes into consideration emission factors and inventories which are essential for developing emission control strategies for determining applicability of permitting and controlling programs and ascertaining the effects of sources and appropriate mitigation strategies. Emission estimates are also important for the related applications such as climate change etc. Emission inventories are studied by emission factors, which mostly lack association of some parameters, such as regional meteorological conditions, socioeconomic and developmental status and industrialization. This study offers a new approach (estimation of imission load) for the calculation of emission inventories after adding the estimation of many possible inputs and outputs. Foremost, average areal concentrations of pollutants are calculated by applying Percentage Weighting Polygon Method (PWP) to Erzurum urban SO2 imission measurement values. Later, mixing height of the study region in Erzurum, Turkey, is assessed by upper atmosphere observations from March 31st to April 1st 2006. Imission load of SO2 in Erzurum urban centre are calculated by a different paradigm based on multiplying urban centre area, mixing height and areal pollutant SO2 concentration values.
