mikroplastpartiklar

Mikroplastpartiklar, also known as microplastics, are tiny pieces of plastic debris that measure less than five millimeters in length. They are formed through two primary pathways: direct manufacturing and secondary fragmentation. Primary microplastics are intentionally produced in small sizes, such as microbeads found in cosmetics and industrial abrasives. Secondary microplastics result from the breakdown of larger plastic items due to environmental factors like sunlight, wave action, and mechanical abrasion.

These ubiquitous particles have been detected in various environments worldwide, including oceans, freshwater bodies, soil, and even the atmosphere. Their small size allows them to be easily ingested by a wide range of organisms, from plankton to larger marine animals. This ingestion raises concerns about potential physical harm, such as blockages in digestive systems, and the leaching of harmful chemicals associated with plastics.

The presence of microplastics in the environment is a growing area of scientific research and public concern. Studies are ongoing to fully understand their ecological impacts, their potential to enter the food chain, and their effects on human health. Efforts to mitigate microplastic pollution include reducing plastic production and consumption, improving waste management, and developing biodegradable alternatives.
