英文摘要 | It has been known that polybrominated dibenzo-p-dioxins/furans (pbdd/fs) share similar or even higher toxicity and bio-accumulativity with polychlorinated dibenzo-p-dioxins/furans (pcdd/fs). in this study, co-analysis method of pbdd/fs and pcdd/fs with isotope dilution high rosolution gas chromatography-high resolation mass spectrometry (hrgc-hrms) was built up based on u. s. epa method 1613 and method to-9a. the samples were exacted and cleaned through acid silica bed, multi-layer silica column and florisil column respectively. the last eluent was concentrated under gentle nitrogen gas flow and spiked with the injection internal standards of pbdd/fs and pcdd/fs. eight congeners of 2,3,7,8-pbdd/fs and 17 congeners of 2,3,7,8-pcdd/fs were quantified. the hrgc-hrms analysis condition for pbdd/fs was: ei(+) and sim model with the resolution >= 10000, the electron emission energy was 50 ev and the filament current was 0.75 ma; db-5 ms fused silica capillary column (60 in x 0.25 mm 1.d., 0.25 mu m); the temperatures of injection, ion source and transfer line were 250 degrees c, 250 degrees c and 305 degrees c, respectively. the carrier gas was helium with the flow 1.0 ml/min. the results showed that the relative standard deviation (rsd) of parallel blank samples was <= 10. 3 % and the recovery of pbdd/fs and pcdd/fs was in the range of 73 % 112%. average quantified values of standard reference sample were in accordance with the certified values and rsd were <=: 12.0%. the method detection limits were: tetrabromodibenzofuran ( tbdf), 0.25 pg/l; tebrachlorodibenzo-dioxin (tbdd), 0.3 pg/mu l; pentabromodibenzo-furans (pebdfs), 0.5 pg/mu l; pentabromodibenzo-,b-dioxin (pebdds), 1.0 pg/mu l; hexabromodibenzo-p-dioxin/furans (hxbdd/fs), 1.5 pg/mu l; tetrachlorodibenzo-p-dioxin/furan (tcdd/fs), 0.5 pg/mu l; pentachlorodibenzodioxin/furans (pecdd/fs) and hexachlorodibenzodioxin/furans (hxcdd/fs), 2.5 pg/mu l; heptachlorodibenzo-p-dioxin/furans (hpcdd/fs) and octachlorodibenzo-p-dioxin/furans (ocdd/fs), 5 pg/mu l. concentrations of pbdd/fs and pcdd/fs in the atmospheric particulate samples of a certain area were 1.01 -2. 43 pg/m(3) and 6.19 - 10. 8 pg/m(3), and gaseous samples were 0.036 - 0. 801 pg/m(3) and 1. 37 - 12. 1 pg/m(3) respectively. compared with other areas in the world, the atmospheric dioxins pollution of the sampling area was at high level. |
