The environmental impact of nanoparticles is another area of concern. Once released into the environment, nanoparticles can interact with various ecosystems in unpredictable ways. They may accumulate in soil and water, potentially causing harm to flora and fauna. The behavior of nanoparticles in the environment, including their mobility, persistence, and bioaccumulation potential, remains poorly understood. This lack of knowledge presents a substantial risk, as it is difficult to predict the long-term environmental consequences of widespread nanoparticle use.
