산업단지 일부지역 주택의 미세먼지(PM10)의 실내, 실외 농도에 관한 연구

Abstract

In this study, we investigated the Indoor and Outdoor concentrations of PM10 in Y area, Jeollanam-do. We conducted personal exposure concentration estimates, and Expoure and Risk Assessments using the Time-weighted Average Model. The concentration of Indoor PM10 was 49.38 µg/m3 and that of Outdoor PM10 was 48.02 µg/m3 , with the Indoor/ Outdoor Ratio value being 1 or more, and it was found that there was an indoor source of pollution. The Indoor/Outdoor Cr ratio value was 1 or more, and the source of Cr was confirmed to be indoor. Based on our analysis, there was a positive correlation between heavy metals Ni, Cr, and Mn (p<0.05). Using the Time-Weighted Average model, we determined the PM10 personal exposure concentration to be 49.36 µg/m3 and confirmed the feasibility of this model in utilizing the PM10 personal exposure concentrations. In this study, the find ings are likely to provide useful data that can be used to determine the concentration of indoor pollutants that are not easy to survey. However, to accurately evaluate indoor air quality, more factors need to be considered and evaluated.
