2. 1. Progestagenic Aquatic Contaminants Act as Potent Androgens in Fish : Experimental Studies in Three-spined Stickleback and Zebrafish

   Author : Johan Svensson; Björn Brunström; Ingvar Brandt; Ian Mayer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pharmaceuticals as contaminants; Progestins; Androgenic properties; Fish; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

   Abstract : The extensive use of pharmaceuticals and their poor removal by wastewater treatment plants has led to the emergence of pharmaceutical compounds as global aquatic contaminants. Progestins, the synthetic analogues to progesterone (P4), are receiving increasing attention as contaminants and have been shown to impair reproduction in fish and amphibians at low ng L-1 concentrations.

4. 2. Fish on drugs : behaviour modifying contaminants in aquatic ecosystems

   Author : Annelie Lagesson; Jonatan Klaminder; Tomas Brodin; Kathryn Arnold; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aquatic ecosystems; Behavioural effects; Ecotoxicology; Endocrine disruptors; Pharmaceuticals; Interaction effects; ekotoxikologi; Ecotoxicology;

   Abstract : Contamination of surface waters is a worldwide problem. One group of emerging contaminants that reach aquatic ecosystems via sewage treatment plant effluents and agricultural run-offs is pharmaceuticals. READ MORE

5. 3. Fate of Pharmaceuticals and Their Transformation Products in Rivers : An integration of target analysis and screening methods to study attenuation processes

   Author : Zhe Li; Anna Sobek; Michael McLachlan; Michael Radke; Kathrin Fenner; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; pharmaceuticals; transformation products; fate; river; suspect screening; non-target screening; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Pharmaceuticals are environmental contaminants causing steadily increasing concern due to their high usage, ubiquitous distribution in the aquatic environment, and potential to exert adverse effects on the ecosystems. After being discharged from wastewater treatment plants (WWTPs), pharmaceuticals can undergo transformation processes in surface waters, of which microbial degradation in river sediments is considered highly significant.

6. 4. Sub-lethal Effects of Anthropogenic Contaminants on Aquatic Invertebrates

   Author : Warren Kunce; Frank Johansson; Jan Örberg; Sarah Josefsson; Jes Rasmussen; Uppsala universitet; []
   Keywords : ecotoxicology; sub-lethal; behavior; biomarkers; thermal tolerance; pesticides; pyrethroids; neonicotinoids; pharmaceuticals; antihistamines; microplastics; mixtures; freshwater; invertebrates; chironomids; damselflies; snails; Biology with specialization in Animal Conservation; Biologi med inriktning mot zoologisk bevarandebiologi;

   Abstract : Anthropogenic contaminants are considered to play a substantial role in the decline of freshwater invertebrate diversity. Sub-lethal effects of many of these contaminants on behaviour and life-history traits of aquatic invertebrates may contribute to their decline. READ MORE

7. 5. Tailoring residue-derived carbon materials for the removal of wastewater contaminants : adsorption and surface properties

   Author : Mirva Niinipuu; Stina Jansson; Jean-Francois Boily; Erik Rosenbaum; Magnus Bergknut; Capucine Dupont; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adsorption; hydrochar; HTC; chemical activation; wastewater; pharmaceuticals; metals; surface properties; biobased residues;

   Abstract : The availability of effective, low-cost wastewater treatment is necessary for increased water recycling and the prevention of environmental pollution on a global scale. Adsorption on activated carbons is commonly applied in wastewater treatment, but the high cost of conventional activated carbons limits the use of this technique. READ MORE
