1. 1. Sorption of novel side-chain fluorinated polymers to sediment - the impact of pH

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Hanna Erléus; [2022]
   Keywords : Scotchgard™; sorption; sediment; pH; side-chain fluorinated polymer surfactants; Lake Hjälmaren.;

   Abstract : Fluorinated compounds are produced on a large scale and their releases are contaminating the environment. Among these are side-chain fluorinated polymers found in technical mixtures of Scotchgard™, which are used as surfactants in fabric coating. READ MORE

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. Effect of PFOS and HBCD on the lipid profiles of developing rainbow trout (Onchorhynchus mykiss) analyzed with UHPLC/Q-TOF-MS

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Vanja Stefanovic; [2018]
   Keywords : Perfluorooctane sulfonate; hexabromocyclododecane; lipid metabolism; UHPLC Q-TOF-MS;

   Abstract : Perfluorooctane sulfonate (PFOS) is widely used in industrial products and is potentially dangerous to the aquatic environment due to not being broken down whether by chemical or biological means, having a half-life of more than 41 years and disrupting hormones. Hexabromocyclododecane (HBCD) is the third most used brominated flame retardant and is of environmental concern as it bioaccumulates and magnifies in the food chain and is highly toxic to aquatic organisms.

5. 4. ETBE as an additive in gasoline: advantages and disadvantages

   University essay from Institutionen för tema

   Author : Hong Yuan; [2006]
   Keywords : Gasoline additive; MTBE; ETBE; BTEX; degradation;

   Abstract : The most widely used gasoline additive methyl tert-butyl ether (MTBE) has been questioned recently, since frequent detection of this compound in groundwater indicates that it could be a risk to our environment. Consequently, legislative efforts have been made by some local governments to phase out the use of MTBE. READ MORE

6. 5. Soil and groundwater contamination with gasoline and diesel oil : assessment of subsurface hydrocarbon contamination resulting from a fuel release from an underground storage tank in Vanstad, Skåne, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Malgorzata Glowacka; [2005]
   Keywords : bensin; diesel; läckage; förorening; underjordstank; gasoline; diesel oil; contamination; underground storage tank; leakage; Earth and Environmental Sciences;

   Abstract : Spills and leaks from storage tanks constitute the most common groundwater contamination source with petroleum products. Gasoline and diesel pools do not spread extensively along the water table, but dissolved constituents are transported in groundwater on relatively larger distances. READ MORE
