The increasing air pollution from the ports has tightened the environmental regulations on bulk ports including the container ports. So advanced ports have been tried to reduce fine dust generated by operation. However, The responds of Busan Port are late compared to other advanced ports. So far, efforts have been made on politics and system areas to monitor and manage the port air pollution. The air quality improvement including port areas will be implemented starting 2020. People near the Gamcheon Port, where mainly handles the bulk cargoes in Busan Port, are damaged by fine dust from the port leading to endless conflict between Gamcheon port and people. Therefore, considering the seasonal weather conditions, this research analyzes the correlation between cargo throughput in Gamcheon port and the density of fine dust in adjacent area. Furthermore, It investigates the main cargoes generating the fine dust by ruling out the seasonal factors.
