   Sammanfattning : Particulate matter suspended in air (i.e. aerosol particles) exerts a substantial influence on the climate of our planet and is responsible for causing severe public health problems in many regions across the globe. LÄS MER

3. 2. Toxicity of Inorganic Aluminium in Humic Streams

   Författare :Cecilia M. Andrén; Emil Rydin; Hans Borg; Ann-Kristin Eriksson Wiklund; Björn-Olav Rosseland; Stockholms universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Inorganic Al; toxicity; acidification; humic streams; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Aluminium (Al) has been recognised as a main toxic factor alongside pH in acidified water ecosystems. The toxic effect of Al has been attributed to inorganic Al (Ali), though there are few in situ studies in ambient humic waters which are the focus of this thesis. LÄS MER

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

   Författare :James M. Armitage; Ian T. Cousins; Michael S. McLachlan; David Ellis; Stockholms universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; perfluoroalkylated substances; global-scale; fate and transport; Environmental chemistry; Miljökemi; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : 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. LÄS MER

5. 4. Brominated flame retardants and perfluoroalkyl acids in Swedish indoor microenvironments : Implications for human exposure

   Författare :Justina Björklund; Cynthia de Wit; Thomas Webster; Stockholms universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; PBDEs; HBCD; PFOS; PFOA; indoor air; indoor dust; breast milk; human exposure; emission; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Humans are exposed to persistent organic pollutants (POPs) such as brominated flame retardants (BFRs, specifically polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD)) and perfluoroalkyl acids (PFAAs, specifically perfluoroalkane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)). They are used in consumer products found in cars, offices, homes and day care centers. LÄS MER

7. 5. Environmental fate of chemicals released from consumer products : Multimedia modelling strategies

   Författare :Anna Palm Cousins; Michael McLachlan; Antonio Di Guardo; Stockholms universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Multimedia fate model; urban model; PBDEs; phthalate esters; indoor environment; emissions; exposure; BDE 209; DINP; DEHP; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : The objective of this thesis was to assess the environmental fate and transport of chemicals emitted from consumer products through the development and application of modelling tools. The following hypotheses were tested: i) Multimedia fate models can be applied in a multistage assessment process to emerging chemicals when limited knowledge exists to identify the likely environmental fate and to direct further research; ii) the indoor environment acts as a source of anthropogenic substances in consumer products to the outdoor environment; and iii) chemical removal pathways in the indoor environment are important for the fate of organic chemicals in densely populated areas.
