  2. 6. Application of two dimensional compound specific carbon-chlorine isotope analyses for degradation monitoring and assessment of organic pollutants in contaminated soil and groundwater

    Author : Charline Wiegert; Örjan Gustafsson; Thomas Hofstetter; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organochlorines; chlorinated ethenes; PCE; TCE; hexachlorocyclohexanes; soil contamination; groundwater contamination; remediation; natural attenuation; biodegradation; carbon isotopes; chlorine isotopes; CSIA; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Nearly 250,000 sites with past and present potentially polluting activities need urgent remediation within Europe. Major pollutants include organochlorines (OCls), e.g. chlorinated ethenes (CEs) and hexachlorocyclohexanes (HCHs), mainly used as industrial solvents and pesticides, respectively. READ MORE

  4. 7. Novel methods of tandem mass spectrometry in life sciences

    Author : Mohammadhassan Gharibi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Mass spectrometry (MS) is a powerful analytical technique widely employed for isotopic analysis and species identification in numerous research fields. Isotopic analysis involves precisely measuring stable isotopes within a sample, offering valuable insights into its origin, environment, and biological processes. READ MORE

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

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

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

  6. 9. Reconstruction of the Southeast Asian hydro-climate using biomarkers and their hydrogen isotopic composition

    Author : Yamoah Kweku Kyei Afrifa; Rienk Smittenberg; Barbara Wohlfarth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; geokemi; Geochemistry;

    Abstract : Southeast Asia is characterized by a monsoonal climate, with distinct wet and dry seasons. This has great impact on societies, agriculture and infrastructures. READ MORE

  7. 10. Responses of benthic-pelagic coupling to environmental change

    Author : Per Hedberg; Monika Winder; Martin Kainz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Benthic-pelagic coupling; Stable isotopes; Fatty acids; Baltic Sea; Plankton; Food webs; Benthos; Marine Ecology; marin ekologi;

    Abstract : Changing abiotic factors, like temperature and light are important drivers of seasonality, affecting aquatic ecosystems and organisms annually in a predictable pattern, structuring species composition, growth, reproduction and trophic interactions. As a consequence of human induced climate change, coastal ecosystems are seeing a disruption in the predictability of annual cycles. READ MORE
