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

    Detta är en avhandling från Umeå : Kemi

    Författare :Daniel Ragnvaldsson; Mats Tysklind; Per Leffler; Lars Lövgren; Bengt-Erik Bengtsson; [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. Chemically Induced DNA Damage in Extended-term Cultures of Human Lymphocytes

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Maria Andersson; Björn Hellman; Leif Busk; [2006]
    Nyckelord :Toxicology; Comet assay; DNA-damaging agents; DNA repair; Extended-term Cultures of Human Lymphocytes; Genotoxicity; Induced DNA damage; In vitro; Mouse Lymphoma Cells; Primary Cell Cultures; Reactive Oxygen Species; Toxikologi;

    Sammanfattning : Generation of DNA damage is regarded to be an important initial event in the development cancer. Consequently, a battery of tests have been developed to detect different types of genotoxic effects in order to be able to predict the potential genotoxicity and mutagenicity of chemicals, including both pharmaceutical drugs and various types of environmental and occupational agents, as well as dietary factors.

  3. 3. Semipermeable membrane devices in monitoring of organic pollutants in the aquatic environment

    Detta är en avhandling från Department of Ecology, Lund University

    Författare :Darius Sabaliunas; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; effect studies; environmental monitoring; organic pollutants; bioconcentration; passive samplers; Semipermeable membrane devices; SPMDs; toxicity; genotoxicity; bioassays; Ecology; Ekologi;

    Sammanfattning : Semipermeable membrane devices (SPMDs) are passive samplers capable of concentrating hydrophobic chemicals from water, sediments, soil and air. They consist of layflat polymeric membrane such as polyethylene containing a thin film of synthetic lipid such as triolein. LÄS MER

  4. 4. Change of toxicity during secondary treatment of industrial sludge containing nitroaromatics

    Detta är en avhandling från Örebro : Örebro universitetsbibliotek

    Författare :Lillemor Gustavsson; Magnus Engwall; Anna Schnürer; Ulrika Welander; Mårten Jönsson; Bo Mattiasson; Göran Dave; [2005]

    Sammanfattning : Wastewater treatment plants in Sweden are facing a great challenge due to the prohibition of depositing organic waste which gained legal force in January 2005. Biological and commercial available alternatives to disposal are composting and anaerobic digestion. LÄS MER

  5. 5. Cancer Risk Assessment of Glycidol Evaluation of a Multiplicative Risk Model for Genotoxic Compounds

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Författare :Jenny Aasa; Margareta Törnqvist; Elaine M. Faustman; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycidol; 3-monochloropropane-1; 2-diol 3-MCPD ; genotoxicity; mutations; micronuclei; hemoglobin adducts; in vivo dose; multiplicative risk model; cancer risk assessment; human cancer risk; Environmental Chemistry; miljökemi;

    Sammanfattning : Humans are exposed to chemical compounds in everyday life, both from the environment and from endogenous processes. Some compounds constitute a risk for cancer development. One such compound is glycidol, which is genotoxic and an animal carcinogen. It is the model compound of this work, partly due to its presence in food. LÄS MER
