Recent studies have reported that indoor house dust contains a large volume of SVOC chemical substances such as phthalates and it is showing a relationship with children’s asthma and allergic dermatitis. In particular, plasticizers contained in PVC building materials such as DBP and DEHP are the primary SVOC substances that pollute indoor environments. Therefore, The Micro-chamber method is to measure the emission rate of SVOCs from building products and to confirm what kind of SVOCs are emitted from a variety of products that are used indoors kindergarten. As results, the DBP and DEHP were detected in all building materials based on the result obtained from measuring the building materials produced in Japan, South Korea, and China. On the other hand, TCEP and TPP were not detected from all the building materials tested in this study. The DBP and DEHP emission rates (95 percentile) from the PVC sheets used for the measurement in this study were 2.60 [ g/m2 h] and 11.63[ g/m2 h] respectively. Moreover, it appears that there is a different type of plasticizer added to each product and detected for each country. In addition, toys, shoes, crayon and eraser were emitted C16, DBP and DEHP and also variety SVOCs like as D6, BHT, DEP, TBP, C20 and DOA. Especially, shoes were detected 9 substances among targeted 12. These results were considered that is because shoes are made a several materials.
