2. 1. Sorption and transformation of polar pharmaceuticals during wastewater treatment studied by hollow fiber liquid phase microextraction

   Author : Estelle Larsson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; pharmaceuticals; wastewater treatment; sludge; hollow fiber liquid phase microextraction;

   Abstract : This thesis addresses the application of hollow fiber liquid phase microextraction as a simple, efficient and environmentally friendly tool to study the fate of four common anti-inflammatory drugs (ketoprofen, naproxen, diclofenac and ibuprofen) during wastewater treatment. Initial experiments verified that this technique is applicable on aqueous as well as suspensions of solid samples, thus greatly simplifying the sample preparation. READ MORE

4. 2. Analytical method development for ultra-trace determination of human pharmaceuticals in aqueous samples. Assessing the performance of a sewage treatment plant

   Author : Saioa Zorita; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecularly imprinted solid-phase extraction; Sample preparation; solid-phase extraction; membrane extraction; human pharmaceuticals; sewage treatment plant; steroid hormones;

   Abstract : Research focus in environmental pollution has recently been extended from more classical environmental pollutants such as PCBs or pesticides to pharmaceuticals and steroid hormones, which are designed to be biologically active and enter the environment primarily through regular domestic use. Consequently, it is important to monitor these substances concentrations in the effluents of sewage treatment plants (STPs) and in the environment in order to evaluate their associated risks.

5. 3. Uptake and bioaccumulation of ionizable pharmaceuticals in aquatic organisms

   Author : Marja L. Boström; Enhet akvatisk ekologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antidepressiva medel; Avloppsvatten; BAF; BCF; Bioackumulation; Biokoncentration; Biomagnifikation; CYP; Extraktionsteknik; HF-LPME; Joniserbara läkemedel; Metabolism; pH; Riskanalys; Tolerans; Antidepressant; BAF; BCF; Bioaccumulation; Bioconcentration; Biomagnification; CYP; Extraction technique; HF-LPME; Ionizable pharmaceutical; Metabolism; pH; Risk assessment; Tolerance; Wastewater;

   Abstract : Pharmaceuticals are found at low concentrations (ng/L) in aquatic environments but bioaccumulation may result in aquatic organisms reaching internal effect levels (µg/L). Environmental hazard assessments include standardized bioaccumulation tests but contrary to the model substances around which the frameworks are built most pharmaceuticals are designed to mimic endogenic chemicals, ionizable, and less lipophilic.

6. 4. Computational studies of photodynamic drugs, phototoxic reactions and drug design

   Author : Klefah Abrahem Klefah Musa; Leif Eriksson; Nino Russo; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NSAIDs; fluoroquinolone; photodegradation; phototoxicity; drug design; DFT; TD-DFT; Biophysical chemistry; Biofysikalisk kemi; Chemistry; Kemi;

   Abstract : The most important criterion when designing new drugs or improving old ones in order to prevent side effects or at least diminish them is drug safety. Treatment of all diseases generally needs use of either topical application or systemic medications (transported in the blood) during a certain period of time. READ MORE

7. 5. A Catalytic and Mechanistic Investigation of Palladium-Phosphine Catalysed Aqueous Hydroxycarbonylation. Steric and Electronic Properties of the Ligands

   Author : Adriana Ionescu; Kemiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oorganisk kemi; Inorganic chemistry; Naturvetenskap; Natural science; Isomerisation of hydroxyalkenes; Mechanism; Regioselectivity; Steric and electronic properties; Hydroxycarbonylation of styrene; Water-soluble phosphines; Palladium; Aqueous catalysis;

   Abstract : The steric and electronic properties of eight water-soluble phosphines (1-8) were investigated by different methods. Phosphines 1-6 were tested as ligands in palladium catalysed hydroxycarbonylation of styrene. READ MORE
