英文摘要	A method was evaluated for the determination of seventeen 2,3 7, 8-substituted polychlorinated dibenzo-p-dioxins and dibenzofurans (pcdd/fs) in atmospheric deposition with isotope dilution-high resolution gas chromatography/high resolution mass spectrometry (hrgc/hrms). sample extracts were cleaned up successively through multi-layer silica gel, alumina and silica gel columns. precise and recoveries of the entire procedure were evaluated by replicate analysis (n = 4) of pcdd/fs standard solutions, with rsd below 7.1% and the recoveries in the range of 62% similar to 103%. the method was also validated by replicate analysis (n = 3) of certified reference material. the values determined were in agreement with those certified, and the rsd below 15%. the detection limits were o.1 pg for 2,3,7,8-tetrachlorodibenzofuran, 0.2 pg for 2,3,7,8-tetrachlorodibenzo-p-dioxin and 0.8 pg for octachlorodibenzo-p-dioxin. pcdd/fs were analyzed in an atmospheric deposition sample, with the deposition flux of 14.02 pg m(-2) day(-1) toxicity equivalent.
