Recently, semi volatile organic compounds, which are emitted from plastics used in building materials, furnitures and home appliances, have become a concern. It is very important to evaluate emission rates of SVOC because it is reported that Di-2-ethylhexyl phthalate, one of the most generally used plasticizers, is harmful to children’s asthma and allergic symptoms at home. In this study, test methods which are used in Europe and Japan as SVOC measurement method are introduced and examined. Outline and characteristic for micro chamber method is also described. In order to measure accurately SVOC, micro chamber demands both low background concentration and high recovery rates for SVOC component. Results show that recovery rates of chamber is significantly improved by carrying out silane treatment for inner wall of chamber |
