Objectives : Numerous studies have revealed the adverse health effects of acute and chronic exposure to particulate matter less than 10 μm in aerodynamic diameter (PM<SUB>10</SUB>). The aim of the present study was to examine the spatial distribution of PM10 concentrations and cardiovascular mortality and to investigate the spatial correlation between PM<SUB>10</SUB> and cardiovascular mortality using spatial scan statistic (SaTScan) and a regression model.
Methods : From 2008 to 2010, the spatial distribution of PM<SUB>10</SUB> in the Seoul metropolitan area was examined via kriging. In addition, a group of cardiovascular mortality cases was analyzed using SaTScan-based cluster exploration. Geographically weighted regression (GWR) was applied to investigate the correlation between PM<SUB>10</SUB> concentrations and cardiovascular mortality.
Results : An examination of the regional distribution of the cardiovascular mortality was higher in provincial districts (gu) belonging to Incheon and the northern part of Gyeonggido than in other regions. In a comparison of PM<SUB>10</SUB> concentrations and mortality cluster (MC) regions, all those belonging to MC 1 and MC 2 were found to belong to particulate matter (PM) 1 and PM 2 with high concentrations of air pollutants. In addition, the GWR showed that PM<SUB>10</SUB> has a statistically significant relation to cardiovascular mortality.
Conclusions : To investigate the relation between air pollution and health impact, spatial analyses can be utilized based on kriging, cluster exploration, and GWR for a more systematic and quantitative analysis. It has been proven that cardiovascular mortality is spatially related to the concentration of PM<SUB>10</SUB>.
