Abstract:

This thesis presents solid phase extraction (SPE) methodologies based on mixed-mode polymeric sorbents; a mixed mode strong anion exchanger (Agilent SampliQ SAX) and a mixed mode strong cation exchanger (Agilent SampliQ SCX). Furthermore, dispersive-SPE based on a quick, easy, cheap, effective, rugged and safe (QuEChERS) method was assessed for applicability in the determination of drug residues. The mixed-mode polymeric sorbents were evaluated for the simultaneous fractionation of drugs that exhibit diverse polarities with acidic, basic and neutral functionalities in biological matrices (plas

This thesis presents the development of chlorophyll, cholic acid, aflatoxin B1 molecularly imprinted polymer (MIP) particles and cholic acid MIP nanofibers for application as selective solid phase extraction (SPE) sorbents. The particles were prepared by bulk polymerization and the nanofibers by a novel approach combining molecular imprinting and electrospinning technology. The AFB1 MIP particles were compared with an aflatoxin specific immunoextraction sorbent in cleaning-up and pre-concentrating aflatoxins from nut extracts. They both recorded high extraction efficiencies (EEs) of > 97 % in

Abstract:

Today, pharmaceutical residues are widely found in nature as a cause of the extensive use of human and veterinary medicine. The pharmaceutical residues have shown to have a damaging impact on flora and fauna. Wastewater Treatment Plants (WWTPs), today, are not designed for pharmaceutical removal, which calls for new methods and the implementation of these to avoid increased concentrations of pharmaceutical residues in nature. This thesis addresses three main areas. Firstly, a pre-study regarding the prevalence of pharmaceutical residues at different parts of a WWTP and in the nearby river, sec

Abstract:

In Ghana, wastewater is frequently used as a source of irrigation water for crops in urban areas, due to water scarcity and an increasing population growth.

This study aimed to determine the status of pharmaceutical pollution in irrigation water used in Chirapatre Estates, a suburb to Kumasi, Ghana.

The purpose of this project was to verify that the ozonation process works in full-scale, thereby verifying a pilot study conducted in 2014 at Tekniska Verken i Linköping AB (TVAB).

This work is focused on the study of penetration of pesticides and pharmaceuticals in the aquatic environment. The aim was to develop and verify the optimal method for long-term monitoring of the occurrence of selected pesticides and pharmaceuticals in surface waters. Two frequently used analgesics ibuprofen and diclofenac, and carbamazepine that is used to treat epilepsy, were chosen from the group of drugs. A group of 41 pesticides were selected for monitoring too. The attention was focused on a group of urea pesticides and phenoxyacetic acids, as well as on selected pesticides falling to th

Abstract:

Le début du 21e siècle a vu naître un intérêt croissant pour la problématique des résidus de médicaments dans les milieux aquatiques. L’apparition de nouvelles technologies analytiques permettant la détection et la quantification de molécules à l’état d’ultra-traces a fortement contribué à cette expansion. Ces améliorations technologiques ont permis la recherche et la quantification de nombreux xénobiotiques dans les différents compartiments aquatiques. Depuis une quinzaine d’années, l’attention des équipes de recherche s’est ainsi portée sur les résidus de médicaments à usage humain ou vétéri

Abstract:

Nonsteroidal anti-inflammatory substances became a very frequently used and constantly evolved group of the drugs, particularly in a human medicine. The risk of their penetration into the environment, especially to the water environment, is rising during the recent years. The diploma thesis is focused on a selection of appropriate separation method and optimization of analytical procedure for the identification and determination of the non-steroidal anti-inflammatory drugs in sewage and surface waters. Salicylic acid, ketoprofen, diclofenac and ibuprofen were chosen from the wide range of NSAI

Abstract:

La Directive Cadre sur l’Eau (2000) fait état de la dégradation du bon état chimique des eaux superficielles et des eaux souterraines. Parmi les polluants émergents mis en cause figurent les résidus de médicaments qui représentent une menace diffuse et potentiellement persistante dans les hydro-systèmes. A ce jour, peu d’études se sont intéressées spécifiquement aux résidus médicamenteux vétérinaires (RMV). En France, la Bretagne est une région d'élevage intensif. 75% des eaux destinées à la consommation humaine (EDCH) sont issues d’eau de surface particulièrement vulnérables. Dans ce contexte

Abstract:

Spridning av läkemedelsrester och andra prioriterade mikroföroreningar i miljön har uppmärksammats och stor oro väckts kring problematiken. Bland observationer som forskare har noterat till följd av antibiotika, hormoner och läkemedel i vattenmiljöer är bland annat bakteriell resistens, könsbyte och sterilitet hos fisk och groddjur. Persistenta föroreningar som per- och polyfluor alkalysyror (PFAS) bryts inte heller ner i naturen och mikroskräppartiklar kan anrikas i vattendrag och orsaka negativa effekter på vattenlevande organismer. Gemensamt för mikroföroreningar är att dessa förekommer oft

This work is based on the current issue of increasing concentrations of pharmaceutical residues in various components of the environment. These new environmental contaminants continuously enter the environment. The most affected environmental component is the aquatic environment. This study is focused on the development and optimization of reliable analytical method, which can determine selected drugs in the aquatic environment (waste waters and surface waters) qualitatively and quantitatively. The target compounds were selected mainly from the group of non-steroidal anti-inflammatory drugs (N

These bioactive chemical residues and their metabolites are ubiquitous and persistently occur in surface water as commonly as the widely recognized persistent organic pollutants (POPs). Therefore, it is necessary to develop convenient analytical methods to study how these residues impact the environment. This work presents a modified method to analyze selected

Abstract:

This study addresses the fundamentals of an important degradation pathway of storing protein pharmaceuticals in an aqueous formulation, oxidation of methionine residues by peroxides. First, a mechanism by which methionine residues are oxidized is identified via ab initio calculations. The major difference of this new mechanism to previous ones is the role of solvent molecules in the oxidation process. Previously proposed mechanisms suggested that solvent molecules facilitate the transfer of hydrogen associated with the oxidation reaction, but the estimated activation energies and pH dependence

Abstract:

Anthropogenically-derived substances, including pharmaceuticals and personal care products, endocrine-disrupting chemicals, and pesticides, are increasingly being detected in drinking water supplies and wastewater effluents. Concerns over the presence of these compounds in water supplies include their ability to impart toxicological activity, their capacity to spread antibiotic resistance, and their potential to affect cell-signaling processes. For these reasons, water treatment processes geared towards removal of these trace organic contaminants are vital. In this work, ozone was used to t
