Estuaries serve as crucial ecosystems, acting as natural filters for pollutants and providing important habitats for aquatic life. However, human activities such as industrialization, urbanization, and agricultural expansion have significantly impacted these ecosystems, resulting in the contamination of estuaries with harmful substances like heavy metals. The Arasalar estuary, located in Karaikal, South India, is one such vulnerable environment facing heavy metal pollution. This study investigates the hydrobiological characteristics of the Arasalar estuary, with a specific focus on the bioaccumulation of hazardous heavy metals in commercially important aquatic species. Heavy metals such as copper, zinc, cadmium, mercury, and lead are known to pose significant risks to aquatic organisms, disrupting ecosystems and affecting food safety. The research highlights the long-term effects of these metals, which bioaccumulate in aquatic species, leading to toxic levels that threaten biodiversity and human health. Through systematic sampling and analysis, this study provides critical data on metal concentrations in the estuary, offering insights into the ecological health of the region. The findings underscore the urgent need for pollution management strategies to safeguard aquatic ecosystems and ensure the sustainability of local fisheries. This research contributes to broader efforts in environmental monitoring and the global understanding of estuarine health, addressing key issues related to pollution and ecosystem resilience.
