“…PBDEs are extensively used in various types of electronic equipment, furniture, plastics, textiles, etc. due to their excellent flame retardant performance (Leonel et al 2014). Since PBDEs can be easily incorporated into different materials and products without making any covalent bonds, they could transport and migrate to different environment through volatilization and effusion etc.…”

Polybrominated diphenyl ethers (PBDEs) have become widespread environmental pollutants all over the world. A newly isolated bacterium from an e-waste recycling area, Stenotrophomonas sp. strain WZN-1, can degrade decabromodiphenyl ether (BDE 209) effectively under aerobic conditions. Orthogonal test results showed that the optimum conditions for BDE 209 biodegradation were pH 5, 25 °C, 0.5% salinity, 150 mL minimal salt medium volume. Under the optimized condition, strain WZN-1 could degrade 55.15% of 65 μg/L BDE 209 under aerobic condition within 30 day incubation. Moreover, BDE 209 degradation kinetics was fitted to a first-order kinetics model. The biodegradation mechanism of BDE 209 by strain WZN-1 were supposed to be three possible metabolic pathways: debromination, hydroxylation, and ring opening processes. Four BDE 209 degradation genes, including one hydrolase, one dioxygenase and two dehalogenases, were identified based on the complete genome sequencing of strain WZN-1. The real-time qPCR demonstrated that the expression level of four identified genes were significantly induced by BDE 209, and they played an important role in the degradation process. This study is the first to demonstrate that the newly isolated Stenotrophomonas strain has an efficient BDE 209 degradation ability and would provide new insights for the microbial degradation of PBDEs.

“…Polybrominated diphenyl ethers (PBDEs) are a class of BFRs and man-made non-naturally occurring chemicals utilized extensively as additives in a wide variety of consumer products, such as electronic devices, vehicles, building materials, airplanes, ships, and furniture foam and upholstery. Owing to their environmental persistence and accumulation in adipose tissues, PBDEs are ubiquitous in the atmospheric environment (Chao et al, 2014a;Cincinelli et al, 2014;Zhou et al, 2014;Shy et al, 2015), in soils, sediments, and plants , water and fishes (Chokwe et al, 2015), and marine and terrestrial mammals (Leonel et al, 2014;Vetter et al, 2015). The animal studies showed that PBDEs disrupted thyroid function and spermatogenesis (Bowers et al, 2015;Huang et al, 2015), impaired mitochondrial function (Huang et al, 2015), induced hepatotoxicity (Ćurčić et al, 2015), caused developmental abnormalities (Berger et al, 2014), affects neurological behaviour (Costa and Giordano, 2011).…”

Because consumer products release them, polybrominated diphenyl ethers (PBDEs) are frequently present in a variety of indoor environments including homes and workplaces. Our goal was to investigate PBDEs contamination of workplace air-conditioner filter dust to assess the health effects of contaminated dust on workers with occupational exposure. Nine medical clinics, four dental clinics, eight factory offices, and six factory clean rooms were selected in southern Taiwan between April 2013 and September 2014. Air-conditioner-filter dust was collected by a high-efficiency vacuum cleaner and then PBDEs were analyzed by a high-resolution gas chromatography coupled with high-resolution mass spectrometry.

“…Concentrations of PBDEs were similar to those observed in cetaceans from the Northern Hemisphere and China . A time‐trend study between 1994 and 2005 in blubber samples of P. blainvillei from Rio Grande do Sul and São Paulo state showed an exponential increase of PBDE concentrations. This finding is similar to the results observed between 1989 and 1998 in the blubber from seals from San Francisco harbor ; however, some studies indicated a considerable decrease of PBDEs during the first decade of the 21st century in the fur seal from the Pacific coast of Japan .…”

Although it is known that emerging contaminants are widespread all over the globe, there is a gap of information about their distribution in some geographical areas, such as Latin America. The present bibliographic work reviews the available literature about the presence of organic emerging contaminants in Latin American freshwater and marine biota between 2002 and 2016 and includes 23 works from Argentina, Brazil, Chile, Colombia, Mexico, and Nicaragua. In particular, the present review provides an overview of the occurrence of continuously present contaminants such as pharmaceuticals, personal care products, and pyrethroid insecticides, as well as the new groups of persistent organic pollutants, the halogenated flame retardants and the perfluoroalkyl substances. A wide overview is provided, considering not only occurrence data but also effects and potential transfer through the food chain. Environ Toxicol Chem 2017;36:1716-1727. © 2016 SETAC.
