Abstract
Daycare centers are an important indoor environment for pre-school children and exposure area withpotential harmful health effects for infants and children who spend most of their daily life. Sampling wasundertaken at 29 daycare centers located Seoul in Korea from January, 2006 to December 2006. The targeto-xylene, TVOC). The mean concentrations of TVOC, toluene, m,p-xylene, ethylbenzene, benzene and styrenein daycare centers were 318.7g/m3, 51.6g/m3, 11.7g/m3, 6.5g/m3, 4.2g/m3, 3.6g/m3, respectively. Tolueneoccupied 17.6 % of the concentration of individual VOCs. The ratio of indoor and outdoor (I/O) of TVOCconcentration of TVOC were measured 433.9g/m3, and these concentrations during third quarter of the yearin summer were higher than the other season. In the other four seasons, TVOC were measured 280.5 in winter,298.3 in spring and 264.6 g/m3 in fal, respectively.
