Phthalate　esters　are　ubiquitous　contaminants　in　indoor　environment.　In　this　study,　we　measured　concentrations　of　phthalate　esters　in　indoor　air　and　indoor　dust.　The　results　indicated　that　concentrations　of　dibutyl　phthalate　(DBP),　butyl　benzyl　phthalate　(BBP),　dicyclohexyl　phthalate　(DCHP),　and　di(2-ethylhexyl)　phthalate　(DEHP)　had　the　same　order　of　magnitude　in　indoor　air.　However,　DEHP　was　the　highest　phthalate　in　indoor　dust.　We　estimated　the　daily　intake　of　phthalate　esters　through　the　routes　of　dust　ingestion　and　air　inhalation.　The　contributions　of　indoor　air　to　DBP　and　DEHP　exposure　were　28%　and　0.28%　of　the　estimated　total　daily　intake,　respectively.　The　contributions　of　indoor　dust　to　phthalate　esters　were　less　than　1%.　Our　results　indicated　that　indoor　air　inhalation　and　dust　ingestion　were　not　significant　routes　of　DEHP　exposure.　However,　DBP　intake　via　inhalation　of　indoor　air　should　be　taken　into　account.
