Removing Heavy Metals from Polluted Soil Via Phytoremediation: An Integrated and Sustainable Method

One of the biggest environmental issues the world is now experiencing is heavy metal pollution. Human endeavours like farming, mining, and operating manufacturing plants can provide people access to the natural world. Polluted soil with heavy metals can damage crops, disrupt the food chain, and pose a health risk to people. Therefore, preventing heavy metal pollution of soil should be the main objective for both individuals and the ecosystem. Heavy metals can accumulate in the different stages of the food chain by being absorbed by plant tissues and penetrating into the biosphere after extended exposure to them in the soil. It is possible to use physical, artificial, and natural remediation techniques to eliminate heavy metals from contaminated soil both in situ and ex situ. Among these, the most affordable, safe for the environment, and regulated method is phytoremediation. Heavy metal contamination can be eliminated by using phytoremediation techniques such as phytoextraction, also phytovolatilisation, phytostabilisation, and phytofiltration. The organic matter produced by plants and the absorption of metals that are present in soil are the two main factors affecting the effectiveness of phytoremediation. In both phytomining and phytoremediation, novel, very effective metal hyperaccumulators are the main emphasis. Following that, this research thoroughly looks at the various frameworks and biotechnological methods that can be used to remove heavy metals in accordance with environmental regulations, highlighting the challenges and restrictions associated with phytoremediation as well as its possible use in the removal of other dangerous pollutants. We also discuss our extensive expertise in safely removing the plants utilised in phytoremediation, which is an important consideration that is often missed when selecting plants to extract heavy metals from polluted environments.
