 Abstract
Pohang is a well-known industrial city in Korea with a large steel-industrial complexes. The biggest environmental issue in the city is associated with fine particulate matter (hereinafter, ). The concentration of is generally dependent on the local emission sources and meteorological conditions. Iron and steel industrial complexes are likely serious pollution sources of in Pohang. In this study, daily data from a large database from the year of 2000 to 2012 were statistically analyzed, together with meteorological data. The average concentrations of were evaluated according to the frequency of Asian dust, haze, mist, and fog. The number of days exceeding short-term standard for were also examined, taking into consideration of weather conditions. It was found that the concentration of was reduced about 18% to 26% because of precipitation. In addition, the effects of wind direction and wind speed on the concentrations were investigated.
