“…Naik et al (26) also observed an increase in the frequency of MN in Mozambique tilapia (Oreochromis mossambicus) exposed to cadmium at 7.4 mg/L, 3.7 mg/L and 1.85 mg/L. Just as in the case of DNA integrity defects, MN induction decreased with time of exposure to metals, which may suggest an attempt by the organism to restore the physiological balance despite the persisting environmental pollution.…”

“…On the other hand, in the study by Singh et al (36), the frequency of MN formed as a result of exposure to cadmium was 2.75 ± 1.25%, with no micronuclei observed in the control group. Studies by Hussain et al (19) and Naik et al (26) also demonstrated that contamination with heavy metals causes an increase in the frequency of MN in erythrocytes. Hussain et al (19) reported a frequency of 5.0 ± 0.63% for single micronucleus induction and 1.44 ± 0.25% for double micronucleus induction in Rohu labeo from the Chenab River.…”

“…The ratio of the DNA in the tail region (tail intensity) is commonly used for quantifying DNA strand breakage and represents the most reliable parameter [67]. Formation of comet tails and micronuclei have been reported with several other toxicants such as hexavalaent chromium in Ctenopharyngodon idellus and Labeo rohita [68,69], Naphthalene-2-sulfonate induced toxicity in blood cells of freshwater fish Channa punctatus [70]; amoxicillin residue on zebra fish (Danio rerio) embryos (Chowdhury et al, 2020); heavy metals on Astyanax lacustris [71], sub lethal concentrations of cadmium chloride exposure in Mozambique tilapia Oreochromis Submit your Manuscript | www.austinpublishinggroup.com mossambicus [72], oil-containing drill cuttings in marine benthic goby Mugilogobius chulae [73]. Corroborative evidence from all these studies highlight the importance of comet assay as an ideal genotoxicity marker in fishes and other marine organisms.…”

“…The micronucleus assay using immature bone marrow erythrocytes of mice has been widely used as a simple and sensitive shortterm screening method in-vivo for determining the mutagenicity of chemical substances [1][2][3] . As this assay uses "whole animals", it has the merits of including such factors as absorption, distribution, and metabolism of the chemical substances in the evaluation 4 .…”
