• Analysis of levels of PCBs, PBDEs, and their metabolites in serum of Indians.
• Profiles of chlorinated and brominated compound differed between study populations.
• High PCB, 3Br BPh, 4Br OH-PBDE, and MeO-PBDE levels suggest high fish consumption.
• High 8Br- and 9Br-PBDE, 8Br-OH-PBDE, and 4Br-BPh levels indicate e-waste exposure.

Within-room and within-building temporal and spatial variations in concentrations of polybrominated diphenyl ethers (PBDEs) in indoor dust

Pages 23-27
Dudsadee Muenhor, Stuart Harrad

• Where and when dust is sampled in a house can influence PBDE levels substantially.
• Levels in an area close to putative sources exceeded markedly those in an area two metres away.
• Substantial variation in PBDE levels exists between different rooms in the same house.

• We provide Canadian national serum PCB and PCDD/F concentration data.
• We examine relationships between concentrations and age/gender.
• We compare Canadian concentrations with those concentrations observed elsewhere.

• PBDEs detected at high concentrations in San Francisco Bay wildlife samples.
• HBCDs, DP, PBEB, and BTBPE were also detected.
• The alternative flame retardants were detected at much lower concentrations than PBDEs.
• Elevated concentrations near highly urbanized areas.
• First measurement of PBDE alternatives in a highly urbanized North American estuary.

Hydroxylated and methoxylated polybrominated diphenyl ethers in blood plasma of humans in Hong Kong

Pages 66-72
Hong-Sheng Wang, Zhuo-Jia Chen, Ka-Lok Ho, Li-Chen Ge, Jun Du, Michael Hon-Wah Lam, John P. Giesy, Ming-Hung Wong, Chris Kong-Chu Wong
Highlights

• 7 MeO-BDEs, 15 OH-BDEs and 3 bromophenols were analyzed in 116 plasma samples.
• 3-MeO-BDE-47, 6-OH-BDE-47 and 2, 4, 5-TBP were their corresponding predominant congeners.
• Accumulation of organo-brominated compounds are from inter-conversion.
• Patterns of relative concentrations of the target analytes were similar in fish diet.

Background exposure to persistent organic pollutants predicts stroke in the elderly

• POPs have recently emerged as a new risk factor for cardiovascular diseases.
• Organochlorine pesticides predicted the future risk of stroke in elderly.
• PCBs predicted the future risk of stroke in elderly.

Polybrominated diphenyl ethers in maternal serum, umbilical cord serum, colostrum and mature breast milk. Insights from a pilot study and the literature

Pages 121-130
K. Jakobsson, J. Fång, M. Athanasiadou, A. Rignell-Hydbom, Å. Bergman

• Low, moderately and highly brominated PBDEs were present in umbilical cord serum.
• Low to moderately brominated PBDEs enrich in colostrum compared to maternal serum.
• Levels of BDE‐153 and BDE‐209 are lower in mature milk than in colostrum.
• The reporting of study designs and results should be improved, to enable comparisons.
