Phthalates　are　typical　emerging　indoor　pollutants　and　ubiquitously　distributed　in　the　indoor　air,　settled　dust　and　on　surfaces.　Phthalates　have　the　potential　to　be　transported　by　human　hands　through　surface　touch　behaviors.　Although　the　contribution　of　subsequent　exposure　via　hand-to-mouth　contact　in　real　indoor　environments　has　not　been　thoroughly　characterized,　it　is　an　important　factor　to　consider.　In　this　study,　six　commonly-used　phthalates　(dimethyl　phthalate　(DMP),　diethyl　phthalate　(DEP),　di-n-butyl　phthalate　(DnBP),　butyl　benzyl　phthalate　(BBzP),　di-2-ethylhexyl　phthalate　(DEHP),　and　di-n-octyl　phthalate　(DOP))　were　measured　in　surface　wipes,　air　and　dust　samples　collected　from　university　dormitories.　Video-cameras　were　used　to　monitor　occupants＇　real　surface　touch　behaviors.　Primary　surfaces　being　touched　included　desks,　cellphones,　keyboards　and　computer　mice,　with　averaged　touch　frequencies　ranging　from　10.4　h-　1　to　25.4　h-1.　Phthalate　levels　on　computer　mice　were　the　highest,　with　DEHP　being　present　as　the　most　predominant　compound　(mean:　2621　mu　g/m2).　Exposures　via　inhalation,　dust　ingestion,　dermal　absorption　and　hand-to-mouth　contact　were　further　estimated　using　Monte-Carlo　simulations.　The　results　suggest　that　the　exposure　resulting　from　surface　touching　and　subsequent　hand-mouthing　could　contribute　35　%-55　%　to　total　exposure　for　targeted　phthalates,　which　were　generally　higher　than　intakes　via　dust　ingestion.　This　study　provides　a　better　understanding　of　phthalate　transfer　through　surface　touch　behavior,　and　highlights　the　significance　of　hand-to-mouth　contact　exposure　in　indoor　environments.
