SUMMARY
Nickel (Ni+2) and chromium (Cr+6) are identified as carcinogenic due to their mechanisms of action. Nickel catalyzes reactions that produce reactive oxygen species, such as peroxide and superoxide, which contribute to oxidative stress. Additionally, it inhibits DNA excision-repair processes and promotes gene silencing through increased histone methylation and decreased acetylation. These biochemical pathways are critical in understanding the carcinogenic potential of these cations.
