Atmospheric Concentrations and Dry Deposition of Polybrominated Diphenyl Ethers in Southern Taiwan

Size-dependent dry deposition of airborne polybrominated diphenyl ethers in urban Guangzhou, China.

Gaseous and size-segregated particulate PBDEs (specifically BDE-47, -99, -183, -207, and -209) in the air were measured in urban Guangzhou at 100 and 150 m above the ground in daytime and at night in August and December 2010, to assess dry deposition of these contaminants accurately with regards to influences of meteorological factors but without confounding surface effects. Particulate PBDEs w...

Depositional characteristics of atmospheric polybrominated diphenyl ethers on tree barks

OBJECTIVES This study was conducted to determine the depositional characteristics of several tree barks, including Ginkgo (Ginkgo biloba), Pine (Pinus densiflora), Platanus (Platanus), and Metasequoia (Metasequoia glyptostroboides). These were used as passive air sampler (PAS) of atmospheric polybrominated diphenyl ethers (PBDEs). METHODS Tree barks were sampled from the same site. PBDEs were...

Polybrominated diphenyl ethers and polybrominated biphenyls in Australian sewage sludge.

This paper presents a brief review of the international scientific literature of polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) in sewage sludge and a survey of these compounds in sewage sludge from 16 Australian wastewater treatment plants (WWTPs). The SigmaPBDE mean concentration in the Australian study was 1137microgkg(-1) dry weight (d.w.) (s.d. 1116) and ranged ...

Polybrominated diphenyl ethers in UK human milk

24 Fourteen tri-deca polybrominated diphenyl ethers (PBDEs) were investigated in 35 human 25 milk samples from Birmingham, UK. While none of the hepta-nona BDEs (the main 26 components of the OctaBDE technical mixture) were above the limit of quantitation (LOQ); 27 BDE-47 (average concentration = 3.3 ng g lipid weight (lw)) was quantified in all samples 28 contributing 34-74% to Σtri-hexa BDEs ...
