Abstract
This study was performed to investigate airborne lead concentration and surface lead contents in preschool facilities. Arithmetic mean of indoor lead concentration in urban area was 44.7 ng/m3 (Geometric mean 32.1 ng/m3) whereas outdoor concentration was 39.5 ng/m3 (GM 22.8 ng/m3). In rural area, airborne lead concentrations were 14.2 ng/m3 (GM 7.9 ng/m3), 12.6 ng/m3 (GM 5.6 ng/m3), respectively. There is statistical significance of the lead concentrations among the locations of preschool facilities. About 37% of qualitative lead check samples was positive and mainly was found in lead based paint. Though lead concentrations on the floor and window sill were well below the US EPA and HUD standard (floor 40 g/ft2 (4.3 g/100 cm2), window sill 250 g/ft2 (26.9 g/100 cm2), respectively), there were much samples which exceed the standard, i.e., 29% of surface wall, 20% of the desk and chair, 100% of painted wood box of tested samples. In view of our study and hazard of lead to children, we recommended that the contents of lead in preschool facilities should be lowered as possible.
