Abstract: Rapid urbanization, industrialization and modernization activities lead to extensive environmental problems and one of the most challenging problems is heavy metal contamination. Heavy metals are important as they cannot be broken down to non-toxic forms and are released into the environment by both natural and anthropogenic sources, especially, mining and industrial activities, and automobile exhausts (for lead). Heavy metals from the soil pass on to the ground water system which in turn causes unhealthiness for human health and environment thereby posing a threat for “Man and Biosphere” by contamination of food chain. In order to reduce the harmful effects, protocols are currently being used for decreasing heavy metal load into the food chain. Since, many of the conventional methods used for rectification are either inconvenient or involves heavy economics, a comparatively sustainable, promising, relatively new eco-friendly green technology has been developed for removal of heavy metals from contaminated sites by utilizing the plants, named phytoremediation. It includes phytoextraction, rhizofiltration, phytostabilization, phytovolatization, and phytodegradation or phytotransformation. Many of the common crops involving more than 400 species of sunflower, maize, mustard, barley, beet, bitter gourd, cauliflower, brinjal, chili, fenugreek, garlic, coriander, ivy gourd, lufa, lady’s finger, mint, radish, spinach, tomato and white gourd are very much in use for remediation of heavy metals. Keeping the importance of the topic in view, the present article deals with different approaches for containment of contaminants from the soil.
