Testo completoHalogenated flame retardants (HFRs) are present in a wide range of materials, such as furniture, textiles, electronic equipment, and so on. They are continuously entering the environment since its demand is increasing every year. Even if some HFRs have been banned, other alternative FRs appeared as replacements. Information regarding the occurrence, behavior and effects of alternative HFRs such as dechlorane plus and related compounds is still scarce even though they have been used for many years. Firstly, two sensitive and selective methodologies by GC-MS-MS were developed for the analysis of HFRs in several environmental and biological matrices. Sediments from different areas were analyzed, representing the first report of HNs in European sediments. Moreover, sludge from various wastewater treatment plants from Spain was also analyzed, representing the first report of Dec 603 in sludge worldwide and showing that DP dominates the HN profile in sludge. Furthermore, DBDPE and BDE-209 concentrations were in the same order, as observed also in sediments. After determining its presence in environmental matrices next logical step was the analysis of species corresponding to different trophic chains. A total of 30 different species from aquatic and terrestrial ecosystems were studied and target compounds were detected in almost all of them, showing their worldwide presence and bioaccumulation capacity. Concentrations showed a geographical dependent behavior, and in addition HNs were detected in areas far away from production sources. Bioaccumulation and biomagnification capacities were also evaluated. Dec 602 showed similar behavior than BDE-47, while Dec 603 and DP were closer to BDE-209. Overall, it seems that more attention should be paid to HNs due to their presence in a wide range of species, and to Dec 602 in particular considering its high concentrations in biota. Furthermore, tissue specific accumulation (blubber-brain) was observed for some compounds. As regards time trends, decrease in PBDE concentrations in birds, especially the components included in the Penta-BDE mixture, was observed. On the contrary, HNs concentrations did not change during the decade studied. Finally, toxicological effects of Deca-BDE and DP commercial mixtures were evaluated. DP caused similar or even higher damage than BDE-209 at lower concentrations.

Testo completoThis thesis presents the study of degradation of two classes of brominated flame retardants (polybrominated diphenyl ethers (PBDEs) and bromophenols) by means of spectroscopic, chromatographic and chemometric methods. We studied two types of degradation: photodegradation and biodegradation Photodegradation Study A general procedure for the study of complex photodegradation processes of environmental pollutants based on chromatographic and spectroscopic monitoring and chemometric method is proposed. Multivariate curve resolution-alternating least squares (MCR-ALS) has been used to resolve concentration profiles and pure spectra of species involved in the photodegradation process and, hence, to elucidate the photodegradation mechanism and to propose the chemical structure of the main photoproducts. In this work are also proposed new data fusion structures (chromatographic (HPLC-DAD-MS) and HPLC /spectroscopy) and related analysis tools that improve the capability to identify the photoproducts formed and the accuracy in the description of the mechanism driving the photodegradation process Based on the proposed methodology a description of the process of photodegradation of decaBDE and six bromophenols and an evaluation of the effect of various factors (solvent polarity, degree of bromination, radiation source ...) on the kinetics and nature of the products formed have been provided. Biotransformation Study In order to have better knowledge about the environmental fate of DecaBDE we have also studied their biodegradation. On the one hand, we have proposed a new methodology for the analysis and determination of possible biodegradation products of PBDEs (hydroxylated derivatives, the OH-PBDEs) by means of liquid chromatography coupled to mass spectrometry. Furthermore we studied the in vitro biodegradation of DecaBDE using rat liver microsomes. Decrease in the amount of original compound during biodegradation was observed, which means that biotransformation occurs. However, biodegradation products were not detected. This indicates that DecaBDE metabolites may have a potential interaction with cellular components, which makes it difficult to detect under the experimental conditions of the methodology used.

Testo completoEl objetivo de la presente tesis consistió en el desarrollo de métodos para el análisis multiresiduo de distintas familias de retardantes de llama en matrices ambientales, y su aplicación en estudios de vigilancia ambiental. Entre los diferentes métodos instrumentales desarrollados, el método basado en la cromatografía de gases acoplada a la espectrometría de masas en modo tándem (GC-EI-MS/MS) fue el más adecuado para el análisis de ocho éteres de polibromodifenilo (PBDEs), nueve nuevos retardantes de llama bromados (NBFRs) y diez retardantes de llama organofosforados (OPFRs) en las matrices ambientales propuestas en este estudio. Para el análisis de agua, se desarrolló un método basado en la extracción en fase sólida utilizando cartuchos HLB. Además, se desarrolló un método de muestreo pasivo para la determinación de cuatro OPFRs y dos NBFRs en agua de río utilizando un muestreador “ceramic dosimeter” y HLB como fase receptora. Para el análisis de sedimentos, lodos de depuradora y polvo, se desarrolló y validó un método utilizando la extracción líquido-sólido en un baño de ultrasonidos con acetato de etilo/ciclohexano (5:2, v/v), y purificación de los extractos con cartuchos florisil. El estudio de vigilancia ambiental incluyó la determinación de los compuestos objeto de estudio en 4 ríos de Inglaterra y España y cinco depuradoras en Catalunya. Se analizaron aguas y sedimentos de los ríos e influentes, efluentes y lodos de las depuradoras. Se observó que los OPFRs son los compuestos más ubicuos y más abundantes en todas las muestra ambientales, mientras el BDE-209 se detectó en los ríos y en los lodos de las depuradoras. Los demás PBDEs, y el DBDPE, HBB, PBEB, PBT, EHTBB, BTBPE y BEHTBP se detectaron con una menor frecuencia. Los estudios de toxicidad con Daphnia magna indicaron que mezclas de OPFRs poseen toxicidad aditiva. Se llevó a cabo la evaluación del riesgo para los distintos ríos estudiados y se observó que no hay un riesgo asociado con los niveles de los OPFRs presente en las aguas, pero se observó un riesgo asociado a la presencia del BDE-209 en las aguas del río Aire en Inglaterra.

Testo completoDiscusses polybromobiphenyls (PBBs) and polybromodiphenyl ethers (PBDEs) are among brominated flame retardants commonly used as additive flame retardants and are now well-known pollutants. They can easily be released from household and office materials if present and tend to settle on dust. Of all the PBDEs congeners, the detection of BDE-209 is considerably more difficult than the lower congeners. Furthermore, there is no available data on the presence of PBBs and PBDEs in indoor dust in South Africa, and, therefore, it was deemed necessary to conduct the present study.
