2. 1. Development of electrochemical sensor and biosensor platforms : detection of therapeutic drugs and heavy metal ions

   Author : Sereilakhena Phal; Solomon Tesfalidet; Britta Lindholm-Sethson; William Siljebo; Pankaj Vadgama; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sensors; electrode surface modification; electrochemical immitance spectroscopy; square wave anodic stripping voltammetry; singular value decomposition; therapeutic drugs; heavy metals;

   Abstract : Electrochemical sensors and biosensors combine the sensitivity of electroanalytical methods with the selectivity of a sensor or biosensor surface. The chemical or biochemical component (receptor) in the sensor recognizes an analyte and produces an electrical signal which is proportional to the analyte concentration. READ MORE

4. 2. Organic complexing agents for remediation of heavy metal contaminated soil

   Author : Zandra Arwidsson; Bert Allard; Mats Åström; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; soil washing; heavy metals; chelators; recycling; NATURAL SCIENCES; NATURVETENSKAP; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

   Abstract : Soil washing of heavy metal contaminated soil may be enhanced by the addition of synthetic chelators. Since many of these chelators may imply stress to soil organisms and are poorly biodegraded, identification and evaluation of effective biodegradable or recyclable chelators (synthetic and/or naturally produced) is of great interest.

5. 3. Experimental Design and Evaluation of Biocide Release from Microcapsules

   Author : Jonatan Bergek; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microsphere; microscopic and macroscopic porosity; controlled release; internal phase separation method; Microcapsule; biocide; polyelectrolyte multilayer;

   Abstract : To protect a painted house façade from mold or algae, anti-growth agents are usually mixed in the paint. The protection of paint systems used in the past relied on heavy metals for protection and are banned today due to their negative impact on the environment. READ MORE

6. 4. Methodology for evaluation of hazards from solid waste and landfill-generated leachate

   Author : Britt-Marie Svensson; Lennart Mathiasson; Lennart Mårtensson; Ann-Sofi Rehnstam-Holm; Kenneth M. Persson; Högskolan Kristianstad; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Analytical protocol; organic pollutants; toxicity test; landfill leachate; leachate treatment; leaching test; waste acceptance criteria; Chemistry; Kemi; NATURAL SCIENCES; NATURVETENSKAP; leaching test; waste acceptance criteria.;

   Abstract : A methodology based on an analytical protocol for evaluation of hazards from landfill leachate and solid waste is described. A dynamic analytical protocol, the LAQUA protocol, including measurements of inorganic and water-quality parameters, polar and non-polar organic marker compounds, and toxicity, was constructed.
