Decontamination of Heavy Metal Contaminated Soils by Phytoremediation: Pot Experimentation
Environment is experiencing severe depletion due to several anthropogenic activities and careless attitude of human beings. In this context, one of the significant issues is soil contamination because of unplanned dumping of hazardous waste from the industries. It should be noted that there are various types of decontamination methods for hazardous chemically contaminated soils; however, those methods are high energy-intensive, expensive, and they further may disturb the natural ecosystem and biodiversity. Therefore, phytoremediation, a sustainable eco-friendly decontamination treatment, is gaining popularity in the arena of contemporary soil remediation practices. On this note, the aim of this present study is to finding out a single plant species and planting density that can decontaminate the high concentration of different heavy metals in contaminated soils. The soil sample has been collected in pots of capacity 3 kg in each from the farming land and spiked with cadmium (150 mg/kg of soil), copper (800 mg/kg of soil), and zinc (1000 mg/kg of soil). Plant species which have been selected for this research are Setaria Italica, Sesamum Indicum, and Vigna Radiata. Chemical analysis has been carried out on soil sample at an interval of 1 week up to 28 days of duration. Subsequently, the experimental observations reveal that the germination, growth rate, biomass production, and contaminant removal of Setaria Italica are better in a very low water content compared to all other plant species.
