국내 유통 페인트 제품 중 주요 VOC성분의 함량분포 특성 연구

Abstract

The emission of VOC from paint products constitutes a significant fraction of their emissions into the air (e.g., approximately 78% in the case of Korea). In this study, we attempted to investigate the major individual VOC components of paint products (e.g., out of 37 target compounds) using GC/FID method. Based on the analysis of 31 paint products currently available on the market, two types of TVOC were measured along with individual components. TVOC was measured as the paint plus thinner (TVOC(T)) and paint only (TVOC(P)). These TVOC concept was compared against the sum of individual VOC (such as ΣVOC). The concentrations of TVOC(T) and ΣVOC ranged between approximately 500~700 and 400~600 g L-1, respectively. Our results indicated that quantifiable VOC mainly consisted of toluene, ethylbenzene, and xylene. It was also found that 15 out of 31 paint products had the VOC contents exceeding the regulation limits. Moreover, the major fractions of TVOC in paint products were dominated by unidentified components. To reduce emission of VOC effectively, it is important to acquire a better knowledge on paint solvents through extended studies.
