Introduction

I. INTRODUCTION

Heavy metal contamination in the environment remains a critical issue, with origins ranging from anthropogenic activities to natural processes. The currect work emphasizes the persistent challenge posed by heavy metals, focusing on the specific context of Na and K pollution in the marine sediments along the Maharashtra coast. The sources of these metals, both anthropogenic and natural, are explored, highlighting the urgency of addressing this environmental concern (Lacerda et al., 1985, NEERI 1985, Chakrabort et al., 2018). The coastal regions along the Maharashtra coast are facing a growing environmental concern due to heavy metal pollution, with sodium (Na) and potassium (K) emerging as pivotal elements in this ecological challenge (Siddiquie et al., 1979). Human activities, both anthropogenic and industrial, contribute significantly to the escalating levels of Na and K in marine sediments, posing a threat to the delicate balance of coastal ecosystems (Karthik et al., 2018). Amid this environmental peril, plants play a crucial role through their intricate phytochemical mechanisms, offering a potential avenue for remediation. This work delves into the nuanced relationship between plants and the variability of Na and K in polluted marine sediments, shedding light on the adaptive strategies employed by coastal plant species (Idrees et al., 2009, Wagay et al., 2023). By exploring the phytochemical intricacies, plant adaptations, and their impact on ecosystem dynamics, this article seeks to unravel the potential of plant-mediated interventions for mitigating the consequences of Na and K pollution along the dynamic coast of Maharashtra (Menon et al., 2011, Sharma et al., 2021).

A. Plant and Phytochemicals in Heavy Metal Contamination

In the complex milieu of heavy metal contamination along the Maharashtra coast, the role of plants and their phytochemical constituents emerges as a potential mitigating factor. While heavy metals like sodium (Na) and potassium (K) pose environmental threats, plants exhibit intricate mechanisms through phytochemicals that contribute positively to the variability of these metals in polluted marine sediments (Mucha et al., 2003, Raut  et al., 2009, Patil and Khan 2017a).

1. Phytochemical Adaptations: Plants possess a remarkable ability to adapt to their surrounding environment, including areas impacted by heavy metal pollution. Phytochemicals, such as antioxidants, polyphenols, and chelating agents, play a pivotal role in plant adaptations by assisting in metal detoxification, reducing oxidative stress, and enhancing overall resilience (Santos  et al., 2021, Khan et al., 2023).
2. Metal Uptake and Accumulation: The roots of coastal plants act as key interfaces between the sediment and the plant itself. Through various physiological processes, plants selectively absorb and accumulate metals, influencing the overall distribution of Na and K in sediments. The interaction between plant roots and metals is mediated by phytochemicals, affecting the fate and transport of these elements (Zingde and Govindan 2000, Patil and Khan 2017b  and Archana et al., 2023).
3. Rhizospheric Processes: The rhizosphere, the region of soil influenced by plant roots, serves as a dynamic zone where plant-microbe interactions occur. Phytochemicals released by roots influence microbial communities, fostering beneficial relationships that contribute to metal immobilization, transformation, and nutrient cycling in the sediment (Ingole and Kadam  2003, Jeba Sonia et al., 2023).
4. Potential for Phytoremediation: Phytoremediation, a sustainable and eco-friendly approach, harnesses the natural abilities of plants and their associated microbes to remediate contaminated environments (Praveena et al., 2008, Amanulla et al., 2023). The phytochemical repertoire of coastal plants can be harnessed for targeted phytoremediation strategies, offering a promising avenue for mitigating Na and K pollution in marine sediments.

In this comprehensive stuidy the intricate interplay between plants, their phytochemical constituents, and the variability of Na and K in polluted marine sediments along the Maharashtra coast. By unraveling the positive effects of phytochemicals, this article aims to underscore the potential of harnessing plant-mediated mechanisms for sustainable environmental management in coastal ecosystems.

Conclusion

In conclusion, this comprehensive review underscores the critical environmental challenge posed by Na and K pollution in marine sediments along the Maharashtra coast. Anthropogenic and natural sources contribute to escalating levels, jeopardizing the delicate balance of coastal ecosystems. However, amidst this environmental peril, plants emerge as crucial allies, employing intricate phytochemical mechanisms to mitigate the consequences of heavy metal contamination. By unraveling the adaptive strategies of coastal plant species, understanding metal uptake processes, and exploring the potential of phytoremediation, this study advocates for sustainable and eco-friendly interventions. The findings pave the way for future research and environmental management strategies aimed at preserving the ecological integrity of the dynamic Maharashtra coast.
