Background: Benzene, toluene, ethylbenzene, and xylene (BTEX) are emitted in the combustion or volatilization of hazardous wastes and fossil fuels. Paint, varnishing agents, and cigarette smoke are also sources of BTEX in living environments. Few studies have examined indoor exposure to BTEX using biomarkers, especially in residential settings. In this study, we evaluated the relationship between residence factors and BTEX exposure using biomarkers among Korean homemakers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
