Anaerobic degradation of decabromodiphenyl ether.
To the authors' knowledge, this is the first report demonstrating microbially mediated reductive debromination of BDE-209 under anaerobic conditions and formation of octa- and nonabromodiphenyl ether congeners. Expand
The use of toxic equivalency factors in assessing occupational and environmental health risk associated with exposure to airborne mixtures of polycyclic aromatic hydrocarbons (PAHs).
A variability of risk estimation for PAH mixtures based on the toxic equivalency factor concept by a factor 2.6 is low and rather unreasonably precise, which underlines the importance of BaP as a surrogate compound of a PAH mixture. Expand
Endocrine activity and developmental toxicity of cosmetic UV filters--an update.
4-Methylbenzylidene camphor and 3-BC delayed male puberty, and dose-dependently affected reproductive organ weights of adult male and female F1 offspring, with partly different effect patterns. Expand
Anaerobic degradation of brominated flame retardants in sewage sludge.
Tetrabromobisphenol A (TBBPA), hexabromocyclododecane (HBCD), and decabromodiphenyl ether (DecaBDE) are high production volume chemicals used as flame retardants in plastics for products such asExpand
Occurrence of UV filters 4-methylbenzylidene camphor and octocrylene in fish from various Swiss rivers with inputs from wastewater treatment plants.
UV filters are widely used compounds in many personal care products and cosmetics, such as sunscreens. After use, UV filters are washed off from skin and clothes and enter the aquatic environment.Expand
Joint sealants: an overlooked diffuse source of polychlorinated biphenyls in buildings.
It is estimated that there are still 50-150 t of PCB present in these materials, acting as diffuse sources, distributed over many hundreds of buildings all over the country and represent a significant but frequently overlooked inventory of PCB. Expand
Temporal trends, congener patterns, and sources of octa-, nona-, and decabromodiphenyl ethers (PBDE) and hexabromocyclododecanes (HBCD) in Swiss lake sediments.
There was no evidence for sediment mediated long-term transformation of PBDE within the observed time span of almost 30 years, despite the high persistence of DecaBDE, environmental debromination occurs, as shown by the detection of a shift in congener patterns of Octa- and NonaBDE in sediments, compared to the respective conGener patterns in technical PBDE products.

Hexabromocyclododecane challenges scientists and regulators.
With 16 potential isomers, this brominated flame retardant is an analytical challenge for environmental scientists and a conundrum for regulators.
2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) poisoning in Victor Yushchenko: identification and measurement of TCDD metabolites
This case of poisoning with TCDD suggests that the design of methods for routine assessment ofTCDD metabolites in human beings should be a main aim of T CDD research in the metabolomic era. Expand
