1. 1. Air quality around preschools in Gothenburg: an evaluation of measurement methods

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Emma Forsmalm; [2023-06-21]
   Keywords : low-cost sensors; passive diffusion samplers; pick-ups and drop-offs; regulatory measurements;

   Abstract : In this study the air quality around four different preschools, chosen to represent different local traffic environments, was measured and the measurement methods used were evaluated. The aim was to compare the information retrieved using different methods, discuss the possible applications of them and finally see if more specific activities, in this case pick-ups and drop-offs, could be seen in the data retrieved.

3. 2. Method development for the analysis of PFAS and neutral precursors in active and passive air samplers

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Pascal Camoiras González; [2019]
   Keywords : ;

   Abstract : Poly- and perfluoroalkyl substances (PFAS) are a chemical class of global concern because of their persistence, toxicity and widespread presence in the environment. This work aimed to develop a robust and reliable method to analyse perfluorohexane sulfonic acid (PFHxS), perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), as well as the neutral volatile PFOS precursors, namely perfluorooctane sulfonamides and perfluorooctane sulfonamidoethanols (FOSAs/FOSEs).

4. 3. Perfluoroalkyl substances (PFASs), flame retardants and cyclic volatile methylsiloxanes in indoor air in Uppsala, Sweden : occurrence and human exposure assessment

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Bo Sha; [2017]
   Keywords : passive air sampling; SIPs; indoor air; PFAS; flame retardants; siloxanes; human exposure;

   Abstract : Indoor air samples were collected from three buildings located at the Swedish University of Agricultural Science (SLU) campus in Ultuna, Uppsala, Sweden and from residences of nine volunteers working in the three buildings. Sorbent-impregnated polyurethane foam (SIP) disk passive air samplers were deployed in different types of rooms in the three buildings including computer room (n = 1), labs (n = 3), lecture rooms (n = 3), offices (n = 8) and dining areas (n = 3) and homes (n = 9) of the volunteers between September and November in 2016.

5. 4. SOURCES OF DIOXINS TO BALTIC AIR Volatilization and Resuspension As Potential Secondary Sources of Dioxins to Air

   University essay from Kemiska institutionen

   Author : Van Anh Le; [2011]
   Keywords : ;

   Abstract : Persistent organic pollutants (POPs) are ubiquitous contaminants characterized by semi-volatility, low water solubility, high lipophilicity and inherent toxicity. A combination of these properties results in long-rang transport, bioaccumulation and biomagnification through food webs. READ MORE
