  • Published : 2005.05.01

Abstract

In this study, we investigated $PM_{10},\;NO_2$, and l-hydroxypyrene(1-OHP) in urine at indoor environments which are 35 houses and 20 hospitals for using air cleaner and non-using air cleaner in Seoul metropolitan area and Kyoung-gi province from April, 2003 to February, 2004. Moreover, we examined effect of improvement for indoor air quality and health effect by concentration of 1-OHP also we investigated removal efficiency by air cleaner for $PM_{10},\;NO_2$, and 1-OHP that were 28.5\%,\;27.4\%,\;and\;42.1\%$ respectively. Concentration of$PM_{10},\;NO_2$, and 1-OHP were $19.02\pm18.14{\mu}g/m^3,\;8.66\pm3.06ppb,\;and\;0.19\pm0.18{\mu}g/g$, creatinine when air cleaner was no worked. The concentration for $PM_{10},\;NO_2$. and 1-OHP were $13.60\pm10.79{\mu}g/m^3,\; 6.29\pm2.71ppb,\;and\;0.11\pm0.10{\mu}g/g$ creatinine, respectively. It was significant statistically. Therefore, it is considered using the air cleaner to remove the partial pollutants in indoor environment and is positive effect for health.
