Risks and Benefits of Zinc Nanoparticles in Aquatic Ecosystems

The crucial component of our ecosystem is the water and aquatic ecology. Marine life and aquatic plants make up the aquatic ecosystem. The aquatic ecosystem and marine life must endure more hardships due to environmental contamination. Nanoparticles are playing a more and more significant role in modern society. The newest scientific area to emerge is nanoparticles. Zinc nanoparticles provide several advantages for aquatic ecosystems but pose some risks to marine life. The synthesis of zinc nanoparticles can be done using a variety of ways. Each method has advantages of its own. After synthesis, it is essential to verify if the synthesis of zinc nanoparticles was carried out correctly. The morphological features, chemical formulas, other characteristics, structural basis, and optical properties. These characteristics are checked by various instruments such as TEM, SEM, AFM, XRD, XPS, EDS, STM, and many more. Zinc nanoparticles can reduce the toxicity level of water bodies. It lowers the bacterial load of the water body. It is also used in wastewater treatment. On the other hand, zinc nanoparticles have very adverse effects, such as accumulating in the aquatic ecosystem. It gets into the food chain, decreasing the animals’ fertility rate. When the zinc nanoparticles are degraded, they release heavy metals, which harms the aquatic ecosystem. It also inhibits the process of photosynthesis in aquatic plants to a very large extent. Thus, using such nanoparticles should be addressed after bringing out excessive research.
