Exposure to high concentrations of mercury is known to cause damage to the nervous system, kidney and liver in human beings [13–15]. It has been reported that mercury interferes with numerous cellular activities, such as cellular repair enzymes to enhance genotoxicity [60] and significantly decreased DNA repair efficiency with the duration of exposure [17]. Mercury compounds are known to be potent chemical agents that cause DNA damage in cells. Strand breaks in DNA, unlike the breaks caused by X-rays, cannot be easily repaired [61]
