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

Abstract

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<0.05). As a result of the comet analysis, the DNA damage detected in the erythrocyte cells of C. carpio showed the presence of genotoxic potential of Cevizdere Stream surface water and Ünye District tap water. The genotoxicity of the surface waters of the Cevizdere Stream, which is the main source of drinking water for the Ünye District in Ordu City, as well as the Ünye District tap waters, was evaluated in vivo for the first time using the Comet assay. This study revealed genotoxic damage in C. carpio due to total heavy metal(loid) pollution in the surface water of Cevizdere Stream and tap water of Ünye District, contributing to a better understanding of the relationship between genotoxicity and heavy metal(loid) pollution.
