  2. 6. Heavy metal removal by floating treatment wetlands: Plant selection

    Author : Maria Schück; Maria Greger; Åsa Danielsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phytoremediation; Rhizofiltration; Heavy metal; Chloride; Floating treatment wetland; Wetland plants; Stormwater; Plant Physiology; växtfysiologi;

    Abstract : Elevated levels of heavy metals and chloride are commonly found in stormwater, as a consequence of pollution from traffic, building material and industries, and the use of salt for deicing in wintertime. Floating treatment wetlands (FTWs), consisting of vegetated rafts that can be placed in stormwater ponds, may be able to reduce heavy metal and chloride concentrations, but until this date have mainly been used for nutrient removal in warm climates.

  4. 7. We bang our heads, therefore I am : subculture as laboratory of identity – the case of heavy metal

    Author : Susanna Larsson; Rolf Lidskog; Emma Engdahl; Philip Lalander; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; subculture; heavy metal; identity; authenticity; ritual; alienation; gender; Sociologi; Sociology;

    Abstract : Subculture is a structure against which identities are both created and guarded. These identities are often socially and practically negotiated against an idea of individual authenticity. The thought of nurturing ones uniqueness while striving to fit in is a common duality and a clear cause of friction within subcultures. READ MORE

  5. 8. Microbial remediation of heavy metal ion polluted soil and water

    Author : Torbjörn Håkansson; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDTA; metal; soil; remediation; Sulphate reducing bactera; biogas; water;

    Abstract : Contamination of soil and water by heavy metal ions (HMs) is a problem all over the world.The use of biological methods alone or in combination with other techniques for treatment of such polluted sites constitutes a major challenge. READ MORE

  6. 9. 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

  7. 10. Protein-based capacitive biosensors for the detection of heavy-metal ions

    Author : Alessia Mortari; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy metal ions; protein; electrode; Biosensor; capacitance;

    Abstract : Some metal ions, such as copper and zinc, are essential nutrients and catalysts in biochemical reactions. Other metal ions, e.g. cadmium and mercury, are highly toxic elements. READ MORE
