Pollution of heavy metal imposes a serious threat to environment. Heavy metals could be present in environment naturally as its part or added by enormous human activities like usage of fertilizers and pesticides, dumping of solid wastes, mining, industrial effluents, burning of fossil fuels, etc. Heavy metal such as zinc, lead, cadmium, mercury, copper, arsenic, etc., are absorbed by the plants from natural environments and through them get entered into the food chain. In plants, above threshold limit of many of these heavy metals show adverse effects and imposes deleterious effects on their growth and development. The impact of heavy metals could be noticed by numerous morphological, biochemical and molecular alterations in plants. These changes are brought disturbance in normal cellular metabolism. Thus, the major by-products of normal cellular metabolism, reactive oxygen species (ROS) could also been thought to be involved in damaging reactions. Excessive generation and accumulation of these ROS creates oxidative stress condition and cytotoxicity. To conquer this situation, plants have various defensive mechanisms including enzymatic and non-enzymatic antioxidants, which detoxify ROS molecules by converting them into non-toxic products.
