Outline of Final Research Achievements

To examine whether land use regression (LUR) model can be used for the exposure assessment in epidemiological studies in Japan, we developed a LUR model for NO2 and NOx in Yokohama.
Annual mean of NOx and NO2 measured at 29 monitoring stations in Yokohama city in 2005 was regressed on land use data such as residential/industrial area, traffic volume, etc. with a manual stepwise method. Distribution of NOx and NO2 concentrations were mapped by using Arc-GIS software. The LUR models we developed has a similar spatial resolution as the LUR models developed in the Western countries. However, it should be necessary to improve the distribution resolution of each pollutant at several places such as near expressways, etc.
