1. 1. Transformation of Micropollutants in the Hyporheic Zone

   Författare :Malte Posselt; Jonathan P. Benskin; Michael Radke; Merle Plassmann; Magnus Breitholtz; Ian Cousins; Gudrun Massmann; Stockholms universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

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

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

   Sammanfattning : 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. LÄS MER

4. 3. Investigation of degradation of toxic substances in fungal cultures by mass spectrometric techniques

   Författare :Åke Stenholm; Mikael Hedeland; Pablo Campo Moreno; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; UHPLC-Q-TOF MS; filamentous fungi; immobilization; polyurethane foam; removal; biodegradation products; Analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

   Sammanfattning : Micropollutants in water are biological or chemical contaminants that are present in ground and surface waters in trace quantities. They are a result of human activity and include pharmaceutically active compounds (PhACs) and endocrine disrupting compounds (EDCs). LÄS MER

5. 4. Chlorinated aliphatic hydrocarbons; an interdisciplinary study of degradation and distribution in complex environments

   Författare :Sofia Åkesson; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Groundwater; Groundwater chemistry; Contamination; Chlorinated solvents; In situ remediation; Biodegradation; PCR; DCIP; CSIA;

   Sammanfattning : In this thesis degradation of chlorinated solvents, e.g., tetrachloroethene (perchloroethylene [PCE]), has been examined, both natural occurring degradation and in situ remediation strategies. LÄS MER

7. 5. Biotechnological treatment of chlorophenol-contaminated water

   Författare :Hamid Zilouei; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; kontroll av utsläpp; Miljöteknik; pollution control; Environmental technology; Cell-based biosensor; Fluorescence in situ hybridization; Bacterial community; Two-liquid phase partitioning bioreactor; Photolysis pretreatment; Biomonitoring; Fixed-biofilm reactors; Toxic organic pollutant; Biodegradation;

   Sammanfattning : Widespread presence of toxic and persistent pollutants in the environment, even at low concentrations, causes risks of adverse effects to human health and the ecosystem. Biological methods for treatment of water streams and removal of persistent pollutants are of great interest due to their simplicity, low cost, and mild operational conditions without harmful by-products.
