2. 1. Antimicrobials in sewage treatment plants : occurrence, fate and resistance

   Author : Marcus Östman; Mats Tysklind; Jerker Fick; Erik Björn; Klaus Kümmerer; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biocides; antibiotics; sewage treatment plants; wastewater; sludge; ozonation; activated carbon; antibiotic resistance; antimicrobials; mass flows; LC-MS MS; environment; advanced water treatment;

   Abstract : The World Health Organization (WHO) has identified antibiotic resistance as a major threat to human health. The environment has been suggested to play an important role in the emergence of antibiotic resistant bacteria. The external environment can act as a source of resistance genes that could potentially be transferred into human pathogens. READ MORE

4. 2. Determination of Antibiotics in the Swedish Environment with Emphasis on Sewage Treatment Plants

   Author : Richard Lindberg; Barbro Andersson; Mats Tysklind; Magnus Johansson; Alfredo Alder; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; antibiotics; environment; sewage treatment plants; antibiotika; miljö; avloppsreningsverk; Environmental chemistry; Miljökemi;

   Abstract : Metoder har utvecklats för att kunna bestämma tolv antibiotikasubstanser, vanliga inom human medicin, i miljöprover. Fokus lades på trimetoprim samt substanser från följande grupper: fluorokinoloner, sulfonamider, penicilliner, cefalosporiner, nitroimidazoler, tetracykliner samt makrolider. READ MORE

5. 3. Performance Assessment of Wastewater Treatment Plants : Multi-Objective Analysis Using Plant-Wide Models

   Author : MAGNUS ARNELL; Ulf Jeppsson; Bengt Carlsson; Hans Bertil Wittgren; Diego Rosso; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; benchmarking; BSM; samrötning; energieffektivitet; växthusgasutsläpp; livscykelanalys; matematisk modellering; avloppsvattenrening; benchmarking; BSM; codigestion; energy efficiency; greenhouse gases; life cycle assessment; mathematical modelling; wastewater treatment; benchmarking;

   Abstract : As the knowledge about anthropogenic impacts of climate change has grown, the awareness of the contributions from treatment of wastewater has widened the scope for wastewater treatment plants (WWTPs). Not only shall ever stricter effluent constraints be met, but also energy efficiency be increased, greenhouse gases mitigated and resources recovered. READ MORE

6. 4. Bio-based recovery of organic carbon from municipal waste streams : Process optimization and microbial community dynamics

   Author : Isaac Owusu-Agyeman; Zeynep Cetecioglu; Elzbieta Plaza; Piet Lens; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

   Abstract : Resource recovery from waste contributes to the transition to a sustainable society. Municipal organic wastes have enormous potential for resource recovery due to the inherent organic content which makes it possible to obtain bio-based chemicals and bioenergy. READ MORE

7. 5. 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.
