Acidification of Freshwater and Impact on Aquatic Life

The acidification of freshwater simply means increasing the acidic content in the water environment, thereby leading to pollution of the water body. Freshwater ecosystems are vital components of our planet’s ecological balance, playing a fundamental role in sustaining life and providing essential services to both wildlife and human populations. Freshwater ecosystems cover a diverse range of habitats such as lakes, rivers, wetlands, and ponds, and are home to a remarkable variety of species that collectively contribute to the rich biodiversity of our planet. The services provided by freshwater ecosystems include biodiversity in freshwater ecosystems, water purification, flood control, and nutrient cycling. The impacts on human societies and the environment include pollution, habitat destruction, climate change, acidification, and the resulting need for conservation efforts. The acidification of freshwater is caused by natural and anthropogenic causes. The natural causes include geological contributions, biological processes, and atmospheric interactions while the anthropogenic causes of freshwater acidification include agricultural practices and industrial emissions, urbanization, and land use changes. Acidification brings about negative impacts on the organisms in the freshwater ecosystem, the habitat, and the food chain at large which can affect even human beings. Freshwater acidification has major effect on aquatic life by reducing the amount of carbonate content that serves as a building block of many organisms in the freshwater ecosystem. The strategies for adaptation and resilience of organisms in acidified ecosystems include physiological, behavioural, and structural changes. Acidification of freshwater ecosystems can be remediated by sustainable management practices to mitigate the impacts of acidification. These include mining, reducing emissions, regulating industry, reforestation, wetland restoration, education and awareness, monitoring and research, lime application, buffer zone establishment, bioaugmentation, nutrient management, restoration of natural hydrology and long-term monitoring.
