영문 초록

Objectives: Personal exposure to air pollution is affected by contact over time and by location. The purpose of this study was to determine the relationship between personal exposure to PM 2.5 and the time-activity patterns of the elderly in urban and rural areas. Methods: A total of 44 elderly participants were recruited for a 24-hour PM 2.5 personal exposure measurement. Twenty-four were from Seoul (urban area) and 20 were from Asan (rural area). Energy expenditure and spatiotemporal positioning were monitored through PM 2.5 measurement. Spearman correlation analysis was conducted to determine the relationship between PM 2.5 Results: Daily average PM 2.5 3 in Asan. Although outdoor exposure was higher in Seoul than in Asan, residential indoor exposure was higher in Asan than in Seoul. Higher PM 2.5 personal exposure in Asan could be explained by longer time in residential indoor environments and higher indoor PM 2.5 concentrations. Seoul elderly had higher energy expenditure, which may be due to the use of mass transportation. Conclusion: Personal exposure to PM 2.5 was higher among Asan elderly than Seoul elderly because of high residential indoor concentrations and longer residential time. Lack of energy spent and higher personal exposure to PM 2.5 might have led to higher risk among the Asan elderly.
