3. 2. Perfluorooctane sulfonate (PFOS) and related chemicals in eggs from Sweden and China

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Yasmin Karimi; [2019]
   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).

5. 4. Determinants of serum perfluoroalkyl acid concentrations in Swedish adolescents and the importance of drinking water as a source of exposure

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Jennifer Nyström; [2019]
   Keywords : perfluoroalkyl acids; PFAAs; adolescents; determinants; exposure; drinking water;

   Abstract : The persistent and toxic perfluoroalkyl acids (PFAAs) are ubiquitously present in the environment and reach humans predominantly via food and drinking water. The aim of the present study was to investigate the effect of low-grade (<10 ng L-1 of single PFAAs) contaminated PFAAs drinking water on serum PFAA concentrations in a representative Swedish adolescent population, and to examine the influence of potential determinants on the variation of the PFAAs serum concentrations.
