Herein,　we　studied　the　occurrence　and　profiles　of　thirteen　PBDE　congeners　in　30　river　sediment　samples　from　Shanghai,　China.　The　concentrations　of　Sigma　13PBDEs　ranged　from　110　to　13,071　pg　g　(-1)　dw,　with　an　average　value　of　2,841　pg　g　(-1)　dw.　BDE-209　was　the　predominant　congener　accounting　for　more　than　65　%　of　total　PBDEs,　demonstrating　that　the　major　source　of　PBDEs　in　sediment　samples　was　associated　with　the　prevalent　use　of　technical　deca-BDE　products.　Moreover,　low　brominated　BDEs　in　sediments　also　came　from　the　degradation　of　higher　brominated　BDEs.　In　addition,　taking　into　consideration　of　dietary　exposure,　PBDEs　in　serum　samples　collected　from　the　locals　were　also　detected　with　range　of　419-26,744　pg　g(-1)　(average　5,561　pg　g　(-1)),　which　suggested　a　relatively　low　burden　of　PBDEs　contamination　to　human　body　compared　with　the　condition　in　other　place.　And　in　serum,　low　brominated　compounds　constituted　the　majority　of　total　PBDE　congeners.
