Nanoparticles have unique properties due to their small size and large surface area. While these characteristics are beneficial in many applications, they also pose potential environmental risks. Some nanoparticles can be toxic to aquatic and terrestrial ecosystems. When released into the environment, these particles can accumulate in soil and water, potentially affecting plants, animals, and microorganisms. Additionally, the persistence of nanoparticles in the environment is still not entirely understood. Their small size makes them difficult to remove using traditional filtration methods, leading to concerns about long-term environmental exposure.
