Role of hydrophytes as bio-indicators of water pollution
Keywords:
Hydrophytes, bio-indicators, water pollution, aquatic ecosystems, phytoremediation.Abstract
Hydrophytes, or aquatic plants, play a significant role as bio-indicators in assessing water pollution due to their sensitivity and adaptive responses to environmental changes. These plants, including submerged, floating, and emergent species, reflect variations in water quality through changes in growth patterns, species composition, and physiological conditions. Their ability to absorb, accumulate, and sometimes detoxify pollutants such as heavy metals, nutrients, and organic contaminants makes them reliable indicators of ecological health. In polluted water bodies, certain tolerant species proliferate, while sensitive species decline, providing measurable evidence of contamination levels. Hydrophytes also contribute to phytoremediation by removing excess nutrients and toxic substances, thereby improving water quality. Compared to conventional physico-chemical methods, they offer a cost-effective and continuous monitoring approach. Thus, hydrophytes serve as efficient, eco-friendly tools for evaluating and managing water pollution in aquatic ecosystems.
