Explanation

Nanoparticles from industry can pollute air, water, and soil due to their small size and resistance to breakdown. This buildup can harm plants, and animals, and even contaminate drinking water.

Nanoparticles can be inadvertently ingested by plants or animals, entering the food chain. As they move up the food chain, they can bioaccumulate in organisms, potentially causing harm at higher trophic levels.

Some nanoparticles can trigger the production of free radicals in cells. Free radicals are highly reactive molecules that can damage cells and contribute to various health problems, including inflammation and cancer.
