摘要

Background: Recent climate change and urbanization enhance the interest in ozone (O3) exposure in vulnerable population. Further advances in exposure assessment technology will be needed for quantifying population exposure to high O3 levels in complex coastal urban area. Aims: In this study, the population exposure to high O3 concentrations was estimated under the major meteorological conditions in a coastal city. Methods: We estimated the population exposure in Busan metropolitan city in Korea by matching O3 concentrations predicted by meteorological-air quality models (WRF-CMAQ) with geographically distributed population. The population data for 2000 were obtained from the Statistics Korea classified by age, gender, and the smallest administrative unit. The distributions of the estimated population exposure to high O3 concentration were compared between the different wind conditions on the high O3 days. Results: The estimated population exposure to high O3 concentrations was largely influenced by the wind condition in the study area. Especially, the condition of inland penetration of sea breeze determined significantly the distributions of the exposure in the city. Conclusions: The results of this study suggest that the estimation of population exposure to high O3 concentrations having high sensitivity on short-term exposure will be needed for considering the characterized local wind conditions in the complex coastal city to improve the uncertainty of the estimation.
