The association of air pollution with daily all-cause mortality in two major industrial cities(Ulsan and Yeochon) was investigated using daily values of TSP, O(c)y, SO(c)u,NO(c)? and CO. General Additive Poisson models with daily mortality as the dependent variable, were used to adjust for temperature, rain tall, and wind speed, as well as for serial correlations in mortality.
O(c)?ad the strong association with dauly mortality in both cities. The magnitude of association in small, for instance, a 1 ppb increase in O(c)?s estimated to increase daily mortality by 1.27% (95% confidence interval (CI) : 0.58~2.35) in Ulsan and 1.16% (95% CI : 0.58~1.97) in Yeochon.
These findings suggests that recent air pollution levels in major two industrial dities may be responsible for substantial number of deaths, and hence remains an important puvlic heath issue.
