Polybrominated dibenzodioxins (PBrDD) and dibenzofurans (PBrDF) in some flame retardant preparations

Polybrominated dibenzodioxins (PBrDD) and dibenzofurans (PBrDF) in some flame retardant preparations. Thoma, H.; Rist, S.; Hauschulz, G.; Hutzinger, O. (Bayreuth, Fed. Rep. Ger.). Chemosphere, 15(9-12), 2111-13 (English) 1986. CODEN: CMSHAF. ISSN: 0045-6535. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 55 2,4,6-Tribromophenol (I) [118-79-6], pentabromophenol (II) [608-71-9], tetrabromobisphenol A (III) [79-94-7], and tetrabromophthalic anhydride (IV) [632-79-1] were analyzed for PBrDD and PBrDF. In tech. grade I, dibromodibenzofuran [103456-40-2], tribromodibenzofuran [103456-41-3], tribromodibenzodioxin [103456-38-8], tetrabromodibenzofuran [106340-44-7], tetrabromodibenzodioxin [103456-39-9] (main components), pentabromodibenzofuran (V) [68795-14-2] and PBrDD were detected. Tech. grade III contained V, hexabromodibenzofuran [103456-33-3] (main components) and octabromodibenzofuran [103582-29-2]. In anal. grade II and IV PBrDF/PBrDD could not be detected.

Impact of fermented brown rice with Aspergillus oryzae (FEBRA) intake and concentrations of polybrominated diphenyl ethers (PBDEs) in blood of humans from Japan

Impact of fermented brown rice with Aspergillus oryzae (FEBRA) intake and concentrations of polybrominated diphenyl ethers (PBDEs) in blood of humans from Japan.

Chemosphere, 57(8), 795-811 (English) 2004 Elsevier B.V. CODEN: CMSHAF. ISSN: 0045-6535. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) The isotope diln. technique was applied for the anal. of new polybrominated di-Ph ethers (PBDEs) calibration std. (both labeled and non-labeled) using high-resoln. GC-high-resoln. MS (HR-GC-HR-MS). The relative response factor (RRF) and relative std. deviation (RSD) for new calibration std. in Finnigan Thermo Electron (MAT-95XL) and Micromass (Autospec Ultima) were more or less identical with mean RRF (0.9882), RSD (0.0865) and CV% of (8. 103582-29-2 and 189084-61-5 which are cas registry numbers are also used here.75). The results also revealed for DeBDE-209 quantification; labeled DeBDE-209 is essential. Furthermore, column injection technique was recommended with a thin film instead of split-less injection to reduce the thermal degrdn. of DeBDE-209 and formation of octabromodibenzofurans (OBDF). Besides, anal. of human blood (n = 156) of FEBRA-intake and non-FEBRA-intake individuals elucidated frequent detection of 18 PBDE congeners. The av. PBDE concns. in non-FEBRA intake and FEBRA-intake humans were 6000-11 000 (mean: 8400) and 5400-15 000 (mean: 9900) resp. on pg/g fat basis. Although FEBRA-intake individuals showed slightly greater PBDEs, computer-normalized concns. of TeBDE-47 corroborate FEBRA-intake individual from 4 family showed reduced concns. The contamination profiles of PBDEs varied in between family, gender as well as geog. International comparison with predominant PBDE congener (TeBDE-47) prevailed lower levels in Japan when compared to Korea, Germany and USA nevertheless, congener specific profiles were different which is in accordance with different tech. PBDE usage in between countries. .
