The　seasonal　variations　and　spatial　distributions　of　4-tert-octylphenol　(OP),　4-nonylphenol　(NP)　and　bisphenol　A　(BPA)　in　surface　waters,　suspended　solids　and　surface　sediments　in　the　Huangpu　River　and　its　tributaries　(Suzhou　River　and　Yunzao　Brook)　were　firstly　investigated.　The　mean　concentrations　of　OP,　NP　and　BPA　in　the　three　rivers　were　10.59,　120.96　and　22.93　ng　L-1　in　surface　waters,　199.87,　2,300.87　and　84.11　ng　g(-1)　in　suspended　solids　and　9.49,　119.44　and　7.13　ng　g(-1)　dry　weight　in　surface　sediments,　respectively.　The　concentrations　of　NP　and　OP　were　higher　in　summer　than　in　winter　in　the　suspended　solids　and　surface　sediments,　while　the　reverse　was　true　in　surface　waters.　Similarly,　the　levels　of　BPA　were　lower　in　summer　than　in　winter　in　surface　sediments,　while　the　opposite　was　true　in　surface　waters　and　suspended　solids.　These　seasonal　variations　might　be　attributed　to　temperature　and　stream　flows.　High　levels　of　OP,　NP　and　BPA　were　found　in　surrounding　river　intersections,　residential　and　industrial　areas.　Their　concentrations　decreased　gradually　with　increasing　distance　from　those　areas,　while　the　lowest　levels　were　measured　in　near　less　urbanized　and　agricultural　areas.　These　phenomena　might　indicate　that　the　stream　current　and　pollutant　source　were　the　major　factors　that　affect　the　spatial　distributions　of　OP,　NP　and　BPA　in　the　three　rivers.　Ecological　risk　assessment　indicated　that　NP　was　the　only　one　of　the　three　pollutants　with　the　potential　to　influence　local　aquatic　organisms.　The　results　of　this　study　provide　scientific　support　for　control　of　these　pollutants.
