Mercury is one of the major toxic heavy metal, poses significant risks to both the environment and human health due to its persistence and its capability to accumulate within ecosystems. The primary route of mercury exposure is through contaminated soil, water and food sources, which can lead to substantial damage to living organisms. In particular, mercury exposure adversely affecting the kidneys, nervous system and other important organs. This study investigates the toxicological effects of Mercury in Radish (Raphanus Sativus) plants through biochemical analysis. The experimental plants were divided into four groups, Group 1, the control group, received no mercury treatment, while Groups 2, 3 and 4 were subjected to mercury concentrations of 50, 100 and 200 mg, respectively. The results demonstrated that mercury exposure led to a significant reduction in important growth parameters. Specifically, the germination percentage, root and shoot lengths, fresh and dry weight, and vigor index were all markedly decreased in the mercury treated groups compared to the control. Biochemical analysis revealed the mercury’s clear negative impact on the metabolic processes in radish plants. Mercury at higher concentrations was associated with a notable reduction in carbohydrate and protein levels, reflecting the plant’s impaired physiological functions. Additionally, the activities of key enzymic antioxidants, such as catalase and superoxide dismutase, were significantly reduced under mercury induced stress. By exploring the biochemical and physiological effects of mercury exposure, this research provides valuable insights into how mercury accumulation impacts plant health.
