Centella Asiatica, also known as Gotu Kola, is a medicinal plant that has been traditionally used for various health benefits. In addition to its medicinal properties, Centella Asiatica has also been found to be effective in phytoremediation due to its ability to accumulate heavy metals from contaminated soils and water bodies. The plant's roots have been shown to have a high affinity for heavy metals such as lead, cadmium, mercury, and arsenic, thereby helping to reduce metal concentrations in the environment.
One of the main advantages of using Centella Asiatica for phytoremediation is its low cost and simplicity compared to traditional remediation methods. The plant is easy to grow and maintain, making it a sustainable and cost-effective solution for treating heavy metal pollution. Additionally, Centella Asiatica is a versatile plant that can tolerate a wide range of environmental conditions, making it suitable for use in different types of contaminated sites.
In addition to its role in phytoremediation, Centella Asiatica can also be used for monitoring heavy metal pollution in the environment. The plant can be grown in contaminated areas to serve as a bioindicator for metal accumulation, allowing researchers to track changes in metal concentrations over time. By studying the metal uptake and accumulation patterns of Centella Asiatica, scientists can gain valuable insights into the extent of heavy metal pollution in specific areas and assess the effectiveness of remediation efforts.
Heavy metal pollution has become a significant environmental issue, posing risks to both environmental and human health. Phytoremediation is an alternative technique that can be employed to treat industrial wastewater for reducing water pollution. Phytoremediation offers a promising solution to this problem by utilizing the natural abilities of plants to accumulate and stabilize heavy metals in contaminated soils and water bodies. This review aims to provide a comprehensive understanding of the phytoremediation process of Centella Asiatica, its advantages, and the role of Centella Asiatica in heavy metal including (lead, cadmium, mercury and arsenic) pollution monitoring and remediation.
