  1. 1. Hazard screening of contaminated sites bioavailable fractions and biological in vitro tools

    Detta är en avhandling från Umeå : Kemi

    Författare :Daniel Ragnvaldsson; Umeå universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hazard screening; bioavailability; metal pollution; in vitro cytotoxicity; water extraction; CCA; arsenic genotoxicity; genotoxicity; Contaminated soil; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Sammanfattning : The environmental bioavailability of contaminants, rather than their total concentrations in the soil compartment play a decisive role for the risks associated with contaminated sites. Various soil constituents and abiotic conditions have strong influence on bioavailability, which may vary substantially between different locations. LÄS MER

  2. 2. Fate and exposure assessment of PCDD/Fs at contaminated sites

    Detta är en avhandling från Umeå : Kemi

    Författare :Annika Åberg; Umeå universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; contaminated sites; dioxins; PCDD F; exposure; food chain; modeling; risk assessment; physical-chemical properties; förorenade områden; dioxiner; PCDD F; exponering; födokedja; modellering; riskbedömning; fysikaliska-kemiska egenskaper; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzo-furans (PCDFs) belong to the most toxic compounds known to science and they are defined as Persistent Organic Pollutants (POPs) under the Stock-holm Convention. The general human exposure to PCDD/Fs is primarily through dietary intake. LÄS MER

  3. 3. On Bayesian Decision Analysis for Evaluating Alternative Actions at Contaminated Sites

    Detta är en avhandling från Umeå : Kemi

    Författare :Jenny Norrman; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; influence diagrams; Bayesian decision analysis; groundwater; data worth analysis; contaminated sites; decision analysis; risk analysis;

    Sammanfattning : Today, contaminated land is a widespread infrastructural problem and it is widely recognised that returning all contaminated sites to background levels, or even to levels suitable for the most sensitive land use, is not technically or financially feasible. The large number of contaminated sites and the high costs of remediation, are strong incentives for applying cost-efficient investigation and remediation strategies that consider the inherent uncertainties.

  4. 4. Investigating the Relation between Efficient, Effective and Sustainable Remediation of Contaminated Sites

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Robert Anderson; [2018]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; decision support; sustainability assessment; efficient remediation; multi-criteria decision analysis; contaminated sites; cost-benefit analysis; effective remediation;

    Sammanfattning : Remediation of contaminated sites reduces negative impacts to humans and the environment, but the process itself is typically associated with high costs to society and large environmental footprints. The sustainable remediation concept has, over the past decade, brought increased attention to the often-overlooked contradictory effects of site remediation. LÄS MER

  5. 5. Assessing Soil Functions for Sustainable Remediation of Contaminated Sites

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Yevheniya Volchko; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soil functions; Contaminated sites soil; minimum data set; soil ecosystem services; sustainability assessment; remediation; soil quality indicators;

    Sammanfattning : Soil contamination is a worldwide problem. Soil remediation is often carried out to reduce the risks posed by contaminants in the soil to human health and environment. Contaminant concentration is typically the only soil quality aspect maintained in remediation projects. LÄS MER
