La pollution des eaux est une problématique majeure qui affecte tant les écosystèmes aquatiques que sur la santé humaine. Par conséquent, la prévention et la surveillance des pollutions constituent donc un enjeu prioritaire afin d’éviter la dissémination de ces polluants. Dans ce contexte, il est essentiel de recourir à la miniaturisation des systèmes et à des méthodes analytiques afin de surveiller en temps réel l'évolution de la pollution sur le terrain.

Abstract:

The input of emerging pollutants into the natural environment is of considerable concern due to their potential implications for the health and development of humans and wildlife. Knowledge of the occurrence and removal (by sewage treatment) of these chemicals is limited and there is a need for these to be investigated if the transport and fate of these chemicals is to be better understood. To develop our understanding, reliable, accurate and precise measurements of these compounds at the very low (often sub-nanogram) concentrations at which they may be found, and may still be toxic, is crucia

Abstract:

Water quality is one of the major challenges that human-ity has to face. Tackling the problem of pollution needs the use of all the resources and expertise available to fill the lack of knowledge and technology. Concern is grow-ing over the many emerging contaminants, including heavy metals ions and plastics, which are omnipresent and poorly managed. In this contest, the presence of micro- and nanoplastics in the marine environment is raising strong concerns. The lack of appropriate methodologies to collect the nanoplastics from water systems imposes the use of engi-neered model nanoparticles

Abstract:

Emerging pollutants are those substances that may be candidates for future regulation on the basis of their (eco)toxicity, their potential effects on human health and the monitoring data on their presence and persistence in various environmental compartments. It is therefore a dynamic definition, which brings new substances or classes of substances, such as human and veterinary drugs, endocrine disruptors, perfluorinated compounds and others, to the attention of the planning and control bodies of the scientific and technical community. An antibiotic, Ciprofloxacin, is considered in this study.

Abstract:

Ever-growing discharges of various emerging chemical contaminants are imposing a great threat of pollution to the coastal environment. Adsorption by sediment plays an essential role in the transport and fate of pollutants in the aquatic system. The sorption of emerging contaminants onto sediment is believed to be largely dependent on the sediment organic matter (SOM). In the present study, laboratory experiments were carried out on the changes of the adsorption behavior of sediment during the sediment aging and diagenesis process.

En este estudio, se ha realizado la síntesis y caracterización de polímeros con impresión molecular usando monómero funcional selectivo para la eliminación de diclofenaco e indometacina en medio acuoso a través del modo discontinuo. El siguiente procedimiento implicado fue la caracterización de la extracción en fase sólida molecularmente impresa usando monómero funcional selectivo para la eliminación y recuperación de

Abstract:

Los contaminantes en el agua han acarreado enfermedades en personas y animales a lo largo de la historia. Hoy en día se pueden encontrar diversos tipos de contaminantes en el agua proveniente de la actividad humana. Hasta ahora se creía que los tratamientos actuales en las plantas depuradoras de agua eran capaces de eliminarlos o retenerlos. Recientemente se ha conocido la existencia de un grupo de contaminantes, denominados Contaminantes Emergentes (CEs), que son capaces de atravesar estos tratamientos sin eliminarse. Estos tienen su origen en diferentes ámbitos, generalmente en fármacos, p

Abstract:

O presente trabalho trata do desenvolvimento um novo material, diatomita modificada por ferro, como ativador dos oxidantes persulfato de sódio e peróxido de hidrogênio para degradar poluentes prioritários (fenantreno e antraceno), diesel e o poluente emergente ácido perfluoroctanóico (PFOA). Os objetivos deste estudo foram comparar esse novo método com métodos convencionais de ativação para esses oxidantes; e estudar, estatisticamente, a relação ótima entre a quantidade deste material e a concentração de oxidante para a degradação dos contaminantes. A diatomita bruta e as diatomitas modificada

Abstract:

In the past 50 years there has been increasing interest and concern over pharmaceutical drugs and their presence in the environment, since they and/or their metabolites could induce toxicological effects and bacterial resistance in living organisms. Conventional sewage treatment plants are not able to efficiently remove these chemicals, reason why these compounds are being introduced into the aquatic environment at concentration levels of parts per-billion (ppb) and parts per-trillion (ppt). Although these concentrations are much lower than those used in medical applications, the related poten

Les méthodes de surveillance de ces flux nécessitent des améliorations, en particulier pour les déversoirs d’orage, structures complexes responsables en grande partie de la dégradation de la qualité des milieux récepteurs.

Os poluentes orgânicos emergentes (POE) são compostos químicos presentes numa variedade de produtos comerciais como medicamentos, produtos de higiene, agrotóxicos, surfactantes, dentre outros, podendo ser encontrados em matrizes ambientais e biológicas. Esses poluentes não são usualmente monitorados ou ainda não possuem legislação regulatória correspondente, mas apresentam risco à saúde humana e ao meio ambiente. Dentre esses POE, podemos destacar o nonilfenol etoxilado, um surfactante não-iônico utilizado no desengraxe alcalino da indústria de galvanoplastia. Esse surfactante possui uma recal

Abstract:

The presence of anthropogenic chemical substances in water resources can affect the ecological balance of aquatic systems, as well as human health, and therefore it is necessary to control their presence in water bodies. The objective of this thesis is the development of analytical methodologies for the determination of phosphorus species and organic micropollutants in water samples. Firstly, two speciation methods for the determination of simple and condensate phosphorus oxoanions have been developed, using HPLC separation coupled to ICP-AES in one methodology and to ICP-MS in the other.

Abstract:

Les substances pharmaceutiques sont classées comme contaminants environnementaux émergents et suscitent une attention croissante du fait de leurs effets potentiellement néfastes sur les écosystèmes. Après excrétion ou élimination inappropriée, les médicaments vont se retrouver dans les eaux de surface, souterraines voire de consommation. De nombreuses études écotoxicologiques ont pour objet la mesure de leurs impacts sur les écosystèmes. Pour autant, ces études portent essentiellement sur le médicament lui-même alors que nombre d'entre eux sont susceptibles de se transformer dans l'environneme
