Nanoplastics are tiny plastic particles that measure less than 100 nanometers in size. They can originate from the breakdown of larger plastic items, such as bottles and bags, or be manufactured intentionally for use in products like cosmetics and coatings. Due to their small size, nanoplastics can easily enter the environment and potentially affect living organisms. These particles are a growing concern because they can be found in various ecosystems, including oceans, rivers, and even in the air. Research is ongoing to understand their impact on health and the environment, as well as their potential effects on wildlife and human health, particularly in relation to microplastics and pollution.
