Hyperaccumulator plants for chromium phytoremediation: A review


Namita Mary Mathew, Anto Joseph, Susan Jose, D Delilah, Shyam Kumar S

Heavy metal contamination is the result of the expansion of industrialisation and urbanisation. Physical and chemical methods of eliminating heavy metals from a polluted environment are inefficient, expensive and unpopular. The use of plants to clean up a polluted environment is known as phytoremediation. This review aims to report tolerant and hyperaccumulator plants for chromium heavy metal detoxification. Hexavalent chromium makes up the majority of chromium, emitted into the environment. Recent studies have identified tolerant and hyperaccumulator plants for chromium detoxification. The studies on chromium absorption capacity of some aquatic macrophytes is reviewed. The review discusses chromium absorption of plants from various sources like simulated wastewater, sewage water from treatment plants, tannery effluent, artificial electroplating and nickel ore mining industry effluent and water samples from various lakes. Most of these researches have proved that chromium toxicity can be reduced in a lab condition, but the results are restricted due to the differences between lab and natural situations. It is necessary to examine the tolerance of native plants that are more adapted and can bioremediate chromium from chromium-contaminated environments.
