The environmental presence of chemicals capable of affecting the endocrine system has become a matter of scientific and public concern after certain endocrine disruptor compounds (EDCs) have been detected in the aquatic environment. In this work, 31 different EDCs and related compounds (suspect EDCs) belonging to different contaminant classes were studied:(More)
A novel fully automated method based on dual column switching using turbulent flow chromatography followed by liquid chromatography coupled to tandem mass spectrometry (TFC-LC-MS/MS) was applied for the determination of endocrine disruptors (EDCs) and related compounds in sediment and sewage sludge samples. This method allows the unequivocal identification(More)
Albumin dialysis using the molecular adsorbent recirculating system (MARS) is a new therapeutic approach for liver diseases. To gain insight into the mechanisms involved in albumin dialysis, we analyzed the peptides and proteins absorbed into the MARS strong anion exchange (SAX) cartridges as a result of the treatment of patients with cholestasis and(More)
Endocrine-disrupting compounds (EDCs) are chemical compounds with the ability to alter the hormonal systems of organisms. Such compounds are used in several industrial and domestic activities and reach the aquatic environment via wastewater discharge. The aim of this study is to assess the occurrence of 30 EDCs and related compounds in the surface waters of(More)
Hospital effluents contribute to the occurrence of emerging contaminants in the environment due to their high load of pharmaceutical active compounds (PhACs) and some endocrine disruptor compounds (EDCs). Nowadays, hospital wastewaters are co-treated with urban wastewater; however, the dilution factor and the inefficiency of wastewater treatment plants in(More)
The objective of this study was to determine different brominated flame retardants (BFRs) in sewage sludge produced in 17 wastewater treatment plants (WWTPs) located in the Northeast of Spain. A total of eight polybrominated diphenyl ether (PBDE) congeners, from tri- to deca-BDEs, were analyzed. The emerging BFR compounds, hexabromobenzene (HBB),(More)
HSA solutions account for 14% of the world market for plasma products. Albumin is indicated for reestablishing and maintaining circulatory volume in situations resulting from traumatic shock, surgery, or blood loss. Albumin is also used in extracorporeal liver support devices that perform blood dialysis against this protein. However, the protein composition(More)
The present study describes a novel, fully automated method, based on column switching using EQuan™ columns for an integrated sample preconcentration and liquid chromatography coupled to tandem mass spectrometry (LC-LC-MS/MS). The method allows the unequivocal identification and quantification of the most relevant environmental endocrine disruptors(More)
The aims of this study are to investigate the presence of 30 substances known or thought to act as endocrine disrupting compounds in tap water from the main water supply areas for region of Madrid, to determine the total estrogenic activity of the samples analysed and to estimate the health risk for the population resulting from those compounds found at(More)
Liver samples from 53 Franciscana dolphins along the Brazilian coast were analyzed for organobrominated compounds. Target substances included the following anthropogenic pollutants: polybrominated diphenyl ethers (PBDEs), polybrominated biphenyls (PBBs), pentabromoethylbenzene (PBEB), hexabromobenzene (HBB), decabromodiphenylethane (DBDPE), as well as the(More)
