초록
In this study, hazardous heavy metals used in 1,081 samples from childcare rooms were investigated with X-ray fluorescence (XRF) and inductively coupled plasma (ICP) analyses. Pb > Ba > Zn > Cr > Sb of heavy metals from paints and vinyl sheets were detected in order of descending concentration. A comparison of the analytical results from portable XRF and ICP revealed that, there was a similar tendency although there was a slight difference between the two measured datasets. The evaluation showed that the hazardous heavy metal of the highest concentration was Cd followed by Cr > Cu > Ba > Co > Pb > Sb. Therefore, XRF could be useful for measuring heavy metals above a certain concentration with the primary screening method. To keep childcare rooms healthy, it is necessary to add Ba, Sb and Zn which are contained in high concentrations in interior finishing materials to environmental safety standards.
