Phytoremediation Potential of Indigenous Plant Species

Abstract

The presence of heavy metals, industrial effluents, mining activities and over use of agrochemicals have become a serious environmental problem, impacting soil quality, water, biodiversity and human health. Remediation methods are typically costly, energy-intensive and can produce secondary pollutants, which makes finding sustainable and environmentally-friendly options a priority. The phytoremediation of pollutants from contaminated soil and water through plants has become more and more popular as a green technology. The use of indigenous plants is especially beneficial for phytoremediation because they adapt to local climatic and soil conditions, have higher survival rates, are easy to maintain and have a positive effect on ecosystem restoration. The present work has been an investigation of the possibility of using some of the indigenous plants for phytoremediation of environmental pollution. It discusses the processes by which native plants can take up, sequester, metabolize, or render immobile contaminants, such as phytoextraction, phytostabilization, phytodegradation, rhizofiltration and phytovolatilization. The study also assesses the effect of plant morphology, root architecture, biomass production and physiology on efficiency of remediation. In addition, the study highlights the ecological and economic benefits of employing indigenous vegetation for restoring degraded lands while conserving biodiversity and promoting sustainable environmental management. The results showed that some native plants are very tolerant to polluted environment and have the potential to significantly lower pollutant level. They can be used as an economic, environmentally sensitive and socially acceptable method to restore the environment instead of traditional engineering solutions. The study finds that the use of indigenous plants in pollution control measures can help increase ecological resilience, restore habitats, and provide long-term environmental sustainability. Future work should emphasize field scale scaling-up and testing the performance of the individual species, as well as the integration of phytoremediation with further monitoring technologies to enhance remediation results.
