Hair　samples　collected　from　e-waste　recycling　workers　(n　=　23　males,　n　=　4　females)　were　analyzed　to　assess　occupational　exposures　to　polybrominated　diphenyl　ethers　(PBDEs)　and　polychlorinated　dibenzo-p-dioxins　and　dibenzofurans　(PCDD/Fs)　at　a　large　e-waste　recycling　facility　in　Taizhou,　eastern　China.　Hair　samples　from　a　reference　population　composed　of　residents　of　Shanghai　(n　=　11)　were　analyzed　for　comparison.　The　mean　concentration　of　Sigma　PBDEs　(range,　22.8-1020　ng/g　dw:　mean,　157　ng/g　dw)　found　in　hair　samples　from　e-waste　recycling　workers　was　approximately　3　times　higher　than　the　mean　determined　for　the　reference　samples.　The　congener　profiles　of　PBDEs　in　hair　from　e-waste　recycling　workers　were　dominated　by　BDE　209,　whereas　the　profiles　in　the　reference-population　samples　showed　comparable　levels　of　BDE　47　and　BDE　209.　Total　PCDD/F　concentrations　in　hair　from　e-waste　workers　(range,　126-5820　pg/g　dw:　mean,　1670　pg/g　dw)　were　approximately　18-fold　greater　than　the　concentrations　measured　in　hair　from　the　reference　population.　Concentrations　of　PCDFs　were　greater　than　concentrations　of　PCDDs,　in　all　of　the　hair　samples　analyzed　(samples　from　e-waste　and　non-e-waste　sites).　Tetrachlorodibenzofurans　(TCDFs)　were　the　major　homologues　in　hair　samples.　Overall,　e-waste　recycling　workers　had　elevated　concentrations　of　both　PBDEs　and　PCDD/Fs,　indicating　that　they　are　exposed　to　high　levels　of　multiple　persistent　organic　pollutants.　(C)　2010　Elsevier　B.V.　All　rights　reserved.
