Investigation of Possible Genotoxicity of Surface and Tap Waters Using the Comet Assay

We tested the hypothesis that chronic exposure to total heavy metal loads in Cevizdere surface water and Ünye District tap water of Ordu Province (Türkiye) may cause a genetic toxic effect in erythrocyte cells of carp (Cyprinus carpio) individuals. For this purpose, total heavy metal (loid)s contents in the surface and tap waters were determined seasonally. It was determined that both Cevizdere surface water and Ünye District tap water caused DNA damage in erythrocyte cells of carp fish, and this damage was statistically significant when compared to control groups (P
