A screening study of relationships among concentrations of algal toxins, PFAS, thiamine deficiency and biomarkers in the European flounder from the southern Baltic Sea

In the disturbed Baltic Sea ecosystem, several animal species display failing health related to exposure toxic compounds, reduced energy metabolism and immune system disorders. order investigate possible associations between fish chemicals affecting defence, levels of algal toxins (bromophenols, hydroxylated polybrominated diphenyl ethers nodularin), perfluorinated alkyl substances (PFAS) thiamine (vitamin B1) were determined in European flounder (Platichthys flesus). Several biomarkers indicating status examined fish, including ethoxyresorufin-O-deethylase (EROD), activities glutathione reductase, S-transferase catalase, addition a large set blood variables. The collected from Hanöbukten south-western parts late August 2018. Regression analyses toxins, PFAS concentration displayed significant with associated detoxification liver function, function fish.
