Bioaccumulation of Perfluoroalkyl Substances and Mercury in Fish Tissue: A Global Systematic Review
Author(s): Bealemlay Abebe Melakea*, Salie Mulate Endalewa and Tamagnu Sinte Alamerewa
PFASs and Hg are persistent, bio accumulative and toxic substances for living organisms. This study aimed to determine bioaccumulation of PFASs and Hg in fish tissue. Previously done peer reviewed papers were searched and collected in the study. Analysis of the results revealed that higher concentrations of PFASs were recorded in fish liver than in fish muscle which may be due to PFASs being proteinophilic and therefore, known to accumulate more in protein rich tissues. The bioaccumulation of PFASs increases with the increase in the carbon chain length. Findings of this study also illustrated that organic mercury is the most abundant form of mercury in fish tissue. Likewise, Hg may be highly accumulated in fish liver and sometimes in the fish muscle which could be due to the presence of high quantities of cysteine rich molecules and higher concentrations of natural metal-binding prote..
