   Keywords : PFOS; PFOA; Chicken Egg; LC-MS MS; Organic egg; Conventional egg;

   Abstract : Dietary intake is one of the major routes of human exposure to perfluoroalkyl and/or polyfluoroalkyl substances (PFAS). The objective of this study was to measure perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonic acid (PFHxS) in organic and conventional egg from Sweden (n=8, consisted of 4 pooled eggs and 4 individuals) and China (n=9, consisted of 4 pooled eggs and 5 individuals) and compare the concentrations of PFAS between the two categories (organic and conventional).

6. 5. 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.
