The measurement of SVOC concentrations on floor in house and risk assessment

本研究建立了测量表面聚氯乙烯地板上SVOCs浓度的方法，并对室内地板上的SVOCs浓度进行了调查。此外，还利用微室对部分建筑产品进行了SVOC释放率的测试。在地板表面检测到的DEHP浓度高于其他增塑剂。我确认清除地板表面的所有DEHP几乎是不可能的，即使积聚的房屋灰尘是用吸尘器吸的。儿童更有可能直接接触地板。还需要进一步的调查，以评估儿童接触DEHP与他们的行为特征的关系，包括爬行和躺在地板上。

this study was developed measurement method to measure the concentration of SVOCs on surface PVC flooring and investigated the concentration of SVOCs on floor in houses. Besides, some building products was tested the emission rate of SVOC by micro-chamber. DEHP on surface of the floor was detected a high concentration than other plasticizers. I confirmed that eliminating all DEHP from the surface of the flooring is nearly impossible, even if the accumulated house dust is vacuumed. Children are more likely to come into direct contact with flooring. Further investigation will be needed to evaluate children`s exposure to DEHP in relation to their behavioral characteristics, including crawling and lying down on the floor.
