Nanoparticles in Aquatic Ecosystems: Origins, Destiny and Ecological Consequences

Kowsika Shanmugam, Elamathi Sakthivel, Janani Rajendran and Prasanna Jeyaraman


DOI: 10.5281/zenodo.10908437


Aquatic ecosystems are facing an increasing amount of nanoparticles (NPs) due to their extensive use and unintentional leakage into the environment. The unique physical and chemical properties as well as the small size of NPs raise concerns about their possible effects on aquatic organisms and ecological processes. The review provides a thorough examination of the origins, destiny, and impacts of NPs in aquatic environments, utilizing a variety of scientific sources. Primary sources of NPs include consumer products, industrial procedures, and artificial NPs utilized in various applications. Subsequent to their release, NPs may undergo intricate processes such as surface modifications, aggregation, dissolution, or other transformations, intricately influencing their behavior and bioavailability. The modes of NP exposure, including ingestion, topical application, or gill absorption, can significantly impinge on the growth, reproduction, and physiological processes of aquatic species. Furthermore, the transformative capability of NPs extends to altering community structure, nutrient cycling, and primary production within ecosystems, thereby eliciting a cascading impact on higher trophic levels. A deep understanding of the complex relationships between NPs and aquatic ecosystems is crucial for accurately evaluating environmental issues and developing successful mitigation plans. Understanding the various effects of NPs on aquatic systems is crucial for promoting sustainable practices and protecting the ecological health of these important habitats.
