Removing Deadly Contaminated Metals from Water just by Plants
Water and land being the welfare natural source which fulfil the requirement of all living organisms needs and for their lively hood. The evolutionary part of humankind leads the resources to get affected with different causes. The most part is of from industries where both resources were affected and losing out its sources. With the list of processes affecting natural sources and environment heavy metal discharge in rivers, ponds, and filling up land with toxic metals are the cause of pollution around living kind. Heavy metals are defined to be the metallic elements that have high density compared to water.
Atomic number of heavy metals are about >20. Some heavy metals are Cadmium, Chlorine, Mercury, and Arsenic all being the strong form of metals contaminating both land and water sources. Due to all such causes, the entire cycle of living organisms get affected as their consumption will lead to both dreadful and non-dreadful diseases. Currently many countries concentrating on clearing this issue that lead the living kind to dangerous part as the concentration heavy metals on the environment is drastically increased in 3-4 decays with activities like burning fossil fuels, discharge of industrial wastes, using fertilizers and it includes all endangered adding to the environment.
Types of Techniques Regarding Pollution Clearance
Phytoremediation has become an effective and affordable technique that helps out in removing and clearing the metal pollutants from the environment and contaminated soil, and water.
Objective and Methodology
Phytoremediation which is a common technique in clearing the pollution through different processes like Phytoextraction, Phytostabilization, Rizofiltration and Phytovolaitilization.
The most common process is Rhizofiltration
Rhizofiltration is mainly used in remediating surface water, extracted groundwater and wastewater with low concentration of contaminants.
The plant used is Brassica juncea used for Cd, Cu, Ni, Zn and Cr where these chemicals are chiefly refined with the roots of the plant and most preferred in removing contaminants from water, they have a fibrous and longer root system that would increase the amount of metals taken from the water sources and effectively removing it.
