  2. 1. Transformation of Micropollutants in the Hyporheic Zone

    Author : Malte Posselt; Jonathan P. Benskin; Michael Radke; Merle Plassmann; Magnus Breitholtz; Ian Cousins; Gudrun Massmann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; micropollutants; hyporheic zone; biodegradation; bacteria; pharmaceuticals; transformation products; LC-MS MS; macrophytes; bedforms; suspect screening; mesocosm; flume; river; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Hyporheic zones (HZs) are reactive transition regions between rivers and aquifers which are thought to play an important role in the attenuation of micropollutants. Micropollutants are chemical substances such as pharmaceuticals, industrial chemicals or personal care products that are found in trace concentrations in the environment and that can be harmful to organisms.

  4. 2. Removal of Organic Micropollutants from Wastewater in Biofilm Systems

    Author : Cecilia Burzio; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pharmaceuticals; Organic Micropollutants; Biological Treatment; Sorption; Aerobic Granular Sludge;

    Abstract : The presence of organic hazardous substances in the aquatic environment, such as pharmaceutically active compounds and personal care products, has become a worldwide issue of increasing environmental concern. Present at concentration of nano- to milligram per liter, they are defined as organic micropollutants (OMPs). READ MORE

    Abstract : The United Nations (UN) has adopted 17 “Sustainable Development Goals” (SDGs) to achieve a clean, better and sustainable future. SDG 6 is to ensure that everyone has access to clean water and sanitation by 2030. READ MORE

  6. 4. Damsel in distress – metabolomics as a novel tool to investigate the effects of wastewater exposure on damselfly larvae

    Author : Jana Späth; Malin L. Nording; Jerker Fick; Stina Jansson; Tuulia Hyötyläinen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomarkers; ecotoxicology; invertebrates; GC-MS; LC-MS; LC-MS MS; metabolomics; micropollutants; pharmaceuticals; risk assessment; ekotoxikologi; Ecotoxicology; Analytical Chemistry; analytisk kemi;

    Abstract : Aquatic organisms, such as aquatic invertebrates, are exposed to anthropogenic pollutants through their environment. These pollutants, despite their low levels, can adversely affect exposed individuals or even entire ecosystems, especially when present in complex mixtures. READ MORE

  7. 5. How to estimate environmental persistence : Understanding persistence of organic micropollutants in rivers from a multidisciplinary perspective

    Author : Claudia Coll Mora; Anna Sobek; Matthew MacLeod; Emma J. Rosi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic micropollutants; biodegradation; persistence; rivers; flume mesocosms; Junge relationships; OECD 308 bottle incubations; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Organic micropollutants such as food additives, pharmaceuticals and personal care products are found in rivers worldwide. Persistence is a key criteria in chemical risk assessment as micropollutants that are persistent pose an exposure hazard to humans and the environment. READ MORE
