| Abstract | 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), pentabromoethylbenzene (PBEB) and decabromodiphenylethane (DBDPE) were also analyzed. The instrumental methodology for the analysis was based on gas chromatography coupled to mass spectrometry with negative chemical ionization (GC-NICI-MS). Moreover, liquid cromathography-quadrupole linear ion trap mass spectrometry (LC-QqLIT-MS/MS) was applied for the determination of hexabromocyclododecanes (HBCDs), tetrabromobisphenol A (TBBPA) and their related compounds, bisphenol A (BPA), monobromobisphenol A (MonoBBPA), dibromobisphenol A (DiBBPA) and tribromobisphenol A (TriBBPA). The most abundant PBDE congener in these sewage sludge samples was BDE-209, with levels ranging from nd to 2303 ng/g dw. In addition, a significant concentrations of DBDPE were also detected, nd-257 ng/g dw, due to their increase production as a Deca-BDE substitute. The emerging compounds HBB and PBEB were detected in 4 WWTPs and their concentrations ranged between nd-5.71 and nd-2.33 ng/g, respectively. TBBPA was detected in quantifiable levels in 15 of the 17 WWTPs analyzed, in concentration range of nd-472 ng/g dw, whereas HBCDs were only found in 8 WWTPs in lower concentrations, between nd and 97.5 ng/g dw. Based on the analysis of sewage sludge samples from different WWTPs and in order to evaluate the impact of these contaminants in the environment, an estimation of BFRs accumulated in the total sewage sludge produced in Catalonia was carried out, with values of 57.8 kg/year, 6.76 kg/year, 13.5 kg/year, 1.56 kg/year, 0.18 kg/year and 0.02 kg/year for PBDEs, DBDPE, TBBPA, HBCDs, HBB and PBEB respectively. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
