Summary
Perfluorinated compounds constitute one of the principal sources of pollution and pose great risk to the aquatic ecosystem. Perflorooctane sulfonate (PFOS) is one of the most common and well-known emerging chemicals since it is widely used and is present in surface water and sediments. Previous studies reported toxic effects of perflorooctane sulfonate on marine organisms. However, there is a scarcity of studies on genotoxic effects of PFOS. This study was undertaken to investigate DNA damage in haemocytes and gill cells of Mytilus galloprovincialis exposed to PFOS using a micronucleus assay (MN). The experiment, which was carried out using increasing concentrations of PFOS (2–6 mg/L), revealed that at the concentration of 4 mg/L, PFOS causes increased genotoxic damage. In summary, results of this study show that the micronucleus test is a reliable tool for the determination of PFOS genotoxicity.
