Trace level analyses of selected perfluoroalkyl substancesin food: Method development and validation

Sadia, Mohammad January 2019 (has links)
To comprise the future requirements to detect low levels of perfluoroalkane acids, includingbranched and linear perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA),and perfluorohexane sulfonic acid (PFHxS) in food items, here analytical methods fordetermination of PFOS, PFOA and PFHxS in six different food matrices (cow milk, butter,chicken egg, chicken meat, beef, and fish) were optimized and validated. The optimizedmethod was based on alkaline digestion and solid-liquid extraction using acetonitrile,followed by solid phase extraction (SPE) using a weak anion exchange cartridge as clean-up.In the case of milk and egg samples, an additional clean-up with graphitized carbon (ENVICarb)was applied. The separation was performed on an ultra-performance liquidchromatograph (UPLC) in negative electrospray ionization mode (MS/MS). The methodshowed an effective way to eliminate taurodeoxycholic acid (TDC), a bile acid that is anendogenous interference compound in egg sample causing ionization suppression duringelectrospray ionization. Validation was performed and resulted in recoveries for the targetanalytes at an acceptable level >70%, the limits of quantification (LOQs) in all matrices were3.1, 3.4, 4.9 pg/g for PFHxS, PFOA, and L-PFOS, respectively. The optimized method wassuccessfully applied to 53 food samples from the Swedish market (n=18) and food samplesprovided by 11 countries through the United Nations Environment Programme project, GlobalMonitoring Plan 2 on Persistent Organic Pollutants (UNEP/GMP2) (n=35). PFOS and PFOAwere detected in all samples, and PFHxS was detected in 80% of the samples. With thismethod, concentrations in the low pg/g range in food samples were quantified including thebranched PFOS isomers. This method can be applied to enforce potential future limit valuesfor PFOS and PFOA as discussed based on the recent European Food Safety Authority(EFSA) report.Further method optimization and validation is still needed for foods of plant origin such asvegetables, flour, nuts and bread.

An investigation of aspects affecting availability and grading of high-risk antibiotics in Sweden. : Group 3

Lindahl, Isabell, Hilowle, Samira, Viktor, Karlsson, Gustaf, Kåreceus January 2019 (has links)
The aim of this report is to investigate aspects affectingavailability and grade high-risk antibiotics in Sweden. 10antibiotics out of 39 antibiotics compiled by the Swedish PublicHealth Authority were studied according to the factors; class(based on chemical structure), industrial production process,number of API manufacturers found, the geographic location of the API manufacturers, number of MAH found in Sweden, number of MAH found in the EEA, number of backorders in Sweden, total length of backorders, currently not provided in Sweden (Number of MAH), assumed profitability per product, uncertainty in annual sales volume (relative standard deviation), uncertainty in annual sales (relative standard deviation), average sales (High/Low) and lastly parallel import to Sweden. The same factors were studied for the remaining 29 antibiotics by group 1 and 2 in order to compile a final grading with the parameters high, medium and low. A grading system was constructed to facilitate the grading system. Itresulted in nine antibiotics graded high, 23 antibiotics graded medium and lastly seven antibiotics were graded low. Also, out of the nine antibiotics formulated as tablets, five were graded ashigh. This drew the conclusion that a correlation between high- risk antibiotics and tablet formulation could be made. Another correlation made was that beta-lactam antibiotics were overrepresented in the antibiotics rated as high. There was also a slight overrepresentation of antibiotics formulated as injection/infusion in the low-risk category. A few limitations occurred during the process of the project such as the research for API manufacturers only included the ones approved in the EEA and the U.S. The grading of the antibiotics assigned to Group 1 and 2 was based only on the tables received from these groups, excluding additional details that may have affected the finalgrading. Nevertheless, the project conceived variation in theresult previously compiled by the Swedish Public Health Authority.
