Characteristics of Air Pollutant Emissions and Distribution for Particulate Matter Concentration of Air Pollution Networks in Gyeongsangbuk-do

Abstract

The objective of this study was to estimate the emission of eight air pollutants including PM10 and PM2.5 from 2012 to 2016, and to estimate the trends of PM10 and PM2.5 concentration using the air pollution monitoring network data in Gyeongsangbuk-do. In this study, the emission statistics provided by CAPSS were used to estimate the emissions and to analyze the emission contributions of each emission source and each air pollutant. The major emission sources of PM10 and PM2.5 in the Gyeongsangbuk-do were showed manufacturing combustion source (62% and 65%). The annual average PM10 and PM2.5 concentration trend showed decrease gradually. The monthly average PM10 and PM2.5 concentration trend showed a general seasonal concentration trend. The particulate matter emissions were estimated using the spatial analysis, and Pohang-si showed the highest emissions in TSP, PM10, and PM2.5. It is suggested that these results could be play an important role as important basic data to manage ambient air quality and establish effective emission reduction strategies in Gyeongsangbuk-do.
