 Environmental pollution is a major global concern due to the rapid growth of industry, energy production, and agriculture. Pollutants can enter the environment through different pathways such as air, soil, and water, leading to serious health and environmental problems. Various approaches exist for treating environmental toxins, but each has its own limitations. Nanotechnology offers promising solutions by using polymers or bioinorganic materials to develop nanoparticles with unique properties that can be used for environmental remediation. These particles can be used to remove pollutants from the environment, making them a viable option for addressing environmental issues. This article was authored by M. D.
