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 $19.02pm18.14{mu}g/m^3,;8.66pm3.06ppb,;and;0.19pm0.18{mu}g/g$, creatinine when air cleaner was no worked. The concentration for $PM_{10},;NO_2$. and 1-OHP were $13.60pm10.79{mu}g/m^3,; 6.29pm2.71ppb,;and;0.11pm0.10{mu}g/g$ 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.
