Benzophenone-type　UV　filters　(BP-UV　filters)　are　frequently　introduced　into　aquatic　environment　from　several　sources.　The　occurrence　and　fate　of　select　BP-UV　filters　and　their　metabolites　were　investigated　in　this　study.　All　target　compounds　were　detected　in　water　samples,　except　for　2,　3,　4-trihydroxybenzophenone　(2,　3,　4-OH-BP).　The　concentration　reached　up　131　ng　L-1　for　5-benzoyl-4-hydroxy-2-ethoxybenzenesulfonic　acid　(BP-4),　30.0　ng　L-1　for　2-hydroxy-4-methoxybenzophenone　(BP-3),　and　mean　value　of　158　ng　L-1　for　benzophenone　(BP).　Concentrations　of　BP-UV　filters　were　not　related　to　recreational　waters　but　with　high　population　frequencies.　In　addition,　five　BP-UV　filters,　namely　2,2＇,4,4＇-tetrahydroxybenzophenone　(BP-2),　2,3,4-OH-BP,　2,4-dihydroxybenzophenone　(BP-1),　4-hydroxybenzophenone　(4-OH-BP)　and　BP　were　investigated　for　probable　sources,　and　found　that　they　originate　from　BP-3　metabolism.　There　is　a　similar　source　for　BP-3,　BP-4,　BP-1,　4-OH-BP　and　BP.　Environmental　risk　assessment　(ERA)　showed　that　risk　quotients　(RQs)　of　BP-4,　BP-3　and　BP　were　2.7,　0.8　and　0.5,　respectively.
