  1. 1. Improved analytical methods for perfluoroalkyl acids (PFAAs) and their precursors – a focus on human dietary exposure

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Author : Shahid Ullah; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental Science; PFASs; PFAAs; PFOA; PFOS; Precursor; FOSA; PAPs; Method development; LC-MS; SPE; Dietary sample; Drinking water; Human exposure; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Per- and polyfluoroalkyl substances are a large group of global environmental contaminants. They can be divided into two sub-groups, 1) perfluoroalkyl acids (PFAAs) and 2) so called precursors, i.e. compounds that can potentially be transformed to form PFAAs. READ MORE

  2. 2. Developmental neurotoxicity of persistent and non-persistent pollutants Behavioral and neurochemical assessments of a perfluorinated compound, pesticides and interaction effects

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Iwa Lee; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brain; Neonatal; Mixtures; Cholinergic system; Organochlorines; Pyrethroids; Organophosphates; Carbamates; Insecticides; PFCs; PFAAs; PFHxS; Endosulfan; Cypermethrin; Chlorpyrifos; Carbaryl; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi;

    Abstract : The focus of this thesis was to investigate developmental neurotoxic effects of different persistent and non-persistent environmental pollutants, alone or in binary mixtures, when exposure occurs during a critical period of brain development, in mice. The compounds investigated included a perfluorinated compound, perfluorohexane sulphonate (PFHxS), and four different pesticides, endosulfan, cypermethrin, chlorpyrifos and carbaryl. READ MORE

  3. 3. The Otter (Lutra lutra) in Sweden Contaminants and Health

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Roos; Uppsala universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Otter Lutra lutra ; PCB; DDT; PFAAs; reproduction; bone; time trends; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : In the 1950s the otter started to decline in numbers and distribution in Sweden and other parts of Europe. In 1972 a game law came into force, listing otter as a species that if found dead should be reported and sent to the authorities. The numbers of dead otters reported from different areas indicate population status and distribution. READ MORE

  4. 4. Comparative avian developmental toxicity of PFAAs

    University dissertation from Örebro : Örebro universitet

    Author : Marcus Nordén; Örebro universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chicken; herring gull; cormorant; PFAA; PFOS; PFOA; toxicity; levels; Biology; Biologi;

    Abstract : Perfluoroalkyl acids (PFAAs) are persistent organic pollutants that can commonly be found in environmental matrixes and wildlife from all over the globe. The PFAAs have been used in applications such as water and dirt repelling treatments for textiles, oil-resistant paper coatings and fire-fighting foams. READ MORE

  5. 5. Fate of perfluoroalkyl acids in the aquatic environment with a focus on mass balance studies

    University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Author : Marko Filipovic; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFAA; PFOS; AFFF; tap water; ground water; WWTP; mass balance; atmospheric deposition; rivers; Baltic Sea; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Perfluoroalkyl substances (PFASs) are man-made chemicals. Their unique properties make them beneficial for a wide range of industrial and consumer product applications, such as in aqueous film forming foam (AFFF), durable water repellent clothing, hydraulic oils and food packaging materials.
