Abstract

Highlights ► We investigate the genotoxic effects of some PCBs (153, 138 and 118 non-dioxin-like compounds and 101 non-dioxin-like compound in fish cells RTG-2. ► The loss of DNA integrity is considered as an initial step for the identification of genotoxic effects. ► The alkaline comet assay and the micronucleus test show clear genotoxic damage after 2 and 24 h to maximum soluble, non-cytotoxic doses. ► Oxidative stress situations seem the most likely explanation for the genotoxic damage.
