Abstract
It is well known that the air quality of 92% of the world is known to exceed the standard of WTO and the death caused by air pollution is almost 6 million per year. The PM2.5 concentration in Korea is the second most serious among the OECD countries following Turkey. Since the PM2.5 has a direct effect on the respiratory system, it has been actively studied in domestic and foreign countries. But current research on the PM2.5 is limited in weather factor or air pollutants. In this paper, we consider the influence of spatial neighbor with weather factor or air pollutants using spatial panel model. We applied the proposed method to 25 borough of Seoul in Korea. The result shows a significant effect of spatial neighbor on the PM2.5 concentration fields.
Keywords : Air pollution, particulate matter 2.5, risk assessment, spatial analysis, spatial panel model.
