Screening of decabromodiphenyl ethane (dbdpe) in lake sediment, marine sediment and peregrine falcon eggs

چکیده
In general terms, BFRs are a controversial group of chemicals. Flame retardants protect lives by increasing fire safety, but at the same time, several of the BFRs are regarded as concerning environmental contaminants. These include polybrominated diphenyl ethers (PBDEs), tetrabromobisphenol A (TBBPA) and hexabromocyclododecane (HBCD). The reasons for concern about BFRs are observed or suspected hazardous environmental behaviour, e.g. high persistence in the environment and adverse biological effects.

Cytotoxicity and apoptosis induction in human HepG2 hepatoma cells by decabromodiphenyl ethane.
OBJECTIVE To investigate the toxic effects of decabromodiphenyl ethane (DBDPE), used as an alternative to decabromodiphenyl ether in vitro. METHODS HepG2 cells were cultured in the presence of DBDPE at various concentrations (3.125-100.0 mg/L) for 24, 48, and 72 h respectively and the toxic effect of DBDPE was studied. RESULTS As evaluated by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl te...
متن کاملSubacute effect of decabromodiphenyl ethane on hepatotoxicity and hepatic enzyme activity in rats.
Information regarding decabromodiphenyl ethane (DBDPE) effects on hepatotoxicity and metabolism is limited. In the present study, Wistar rats were given oral DBDPE at different doses. DBDPE induced oxidative stress, elevated blood glucose levels, increased CYP2B2 mRNA, CYP2B1/2 protein, 7-pentoxyresorufin O-depentylase (PROD) activity, and induced CYP3A2 mRNA, CYP3A2 protein, and luciferin benz...
متن کاملPhotolytic degradation of decabromodiphenyl ethane (DBDPE).
The photolytic degradation of decabromodiphenyl ethane (DBDPE), an alternative flame retardant to decabromodiphenyl ether, was investigated in a variety of matrixes (n-hexane, tetrahydrofuran, methanol/water, humic acid/water, and silica gel) by irradiation under ultraviolet light and in n-hexane under natural light. Photolytic degradation of DBDPE occurs in all the matrixes investigated within...
متن کاملPBDE, HBCD, and novel brominated flame retardant contamination in sediments from Lake Maggiore (Northern Italy).
The reduction in the use of polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD) has opened the way for the introduction of novel brominated flame retardants (NBFRs) in place of the banned formulations. Important representatives of this group are decabromodiphenyl ethane (DBDPE), 1,2-bis(2,4,6-tribromophenoxy) ethane (BTBPE), hexabromobenzene (HBB), and pentabromoethylbenzen...
متن کاملNovel flame retardants, 1,2-bis(2,4,6-tribromophenoxy)ethane and 2,3,4,5,6-pentabromoethylbenzene, in United States' environmental samples.
Two brominated flame retardants, 1,2-bis(2,4,6-tribromophenoxy)ethane (TBE) and 2,3,4,5,6-pentabromoethylbenzene (PEB), were detected and identified in ambient air samples from various sites in the United States. The identifications were confirmed by comparing the gas chromatographic retention times and mass spectra of the compounds found in the environment with those of authentic materials. Ge...
