Mikromuovi

Mikromuovi is a term used to describe very small plastic particles. These particles are typically defined as being less than 5 millimeters in size, though some definitions extend this upper limit. Mikromuovi can originate from a variety of sources. They can be intentionally manufactured, such as in the form of microbeads found in some personal care products like exfoliants or toothpaste. More commonly, mikromuovi are the result of the breakdown of larger plastic items through processes like photodegradation (exposure to sunlight) and mechanical abrasion.

The environmental impact of mikromuovi is a growing concern. Due to their small size, they are easily dispersed throughout the environment, particularly in aquatic ecosystems. Mikromuovi have been found in oceans, rivers, lakes, and even in drinking water. Once in the environment, they can be ingested by a wide range of organisms, from plankton to fish and birds. The long-term effects of this ingestion on wildlife and potentially on human health are still under investigation. Research is ongoing to better understand the sources, pathways, and impacts of mikromuovi, as well as to develop strategies for their reduction and removal.
