  1. 1. Modeling the global fate and transport of perfluoroalkylated substances (PFAS)

    University dissertation from Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

    Author : James M. Armitage; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; perfluoroalkylated substances; global-scale; fate and transport; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Perfluoroalkylated substances (PFAS) are persistent contaminants that are widely distributed in the global environment. Despite the fact that these chemicals have been manufactured and used for over 50 years, there has been little scientific and regulatory interest until very recently. READ MORE

  2. 2. Integrating biochemical and growth responses in ecotoxicological assays with copepods

    University dissertation from Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

    Author : Ulrika Dahl; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Environmental chemistry Environmental toxicology; NATURVETENSKAP Kemi Miljökemi Miljötoxikologi; tillämpad miljövetenskap; Applied Environmental Science;

    Abstract : The understanding of effects of chemical exposure in nature is lagging behind. Predictions of harmful effects of chemicals on aquatic organisms rely mainly on ecotoxicity tests. READ MORE

  3. 3. Measurement and source apportionment of ubiquitous soot black carbon in sediments

    University dissertation from Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

    Author : Marie Elmquist; Stockholms universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The pyrogenic particles formed from incomplete combustion of organic matter are often termed black carbon (BC) and they partake in many important biogeochemical processes. For instance, BC in water and sediment affects the solid-water partitioning of hydrophobic organic pollutants reducing their bioavailability. READ MORE

  4. 4. Biomarkers in perch (Perca fluviatilis) used in environmental monitoring of the Stockholm recipient and background areas in the Baltic Sea

    University dissertation from Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

    Author : Tomas Hansson; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomarker; DDT; environmental monitoring; EROD; fish; GSI; nanoinjection; PAH; PCB; Perca fluviatilis; perch; reproduction; NATURAL SCIENCES Chemistry Environmental chemistry Environmental toxicology; NATURVETENSKAP Kemi Miljökemi Miljötoxikologi; tillämpad miljövetenskap; Applied Environmental Science;

    Abstract : This thesis reports the results of biomarker measurements in three environmental monitoring projects. In the first project, which was part of the Swedish national environmental monitoring, biomarkers were measured annually in female perch (Perca fluviatilis) in two background areas in the Baltic Sea during 1988–2000, resulting in a unique 13-year series of measurements.

  5. 5. Biochemical studies of thiamine deficiency in Baltic salmon (Salmo salar)

    University dissertation from Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

    Author : Gun Åkerman; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Environmental chemistry Environmental toxicology; NATURVETENSKAP Kemi Miljökemi Miljötoxikologi; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The first part of this thesis is about the development of a method to inject various substances into the yolk of fish eggs. The method was named nanoinjection and enabled the injection of volumes as small as 10-9 L into the yolk of single fish eggs directly after fertilization, with insignificant mortality due to the injection.
