Tiny plastic particles less than 5 millimeters in size, resulting from the breakdown of larger plastics or produced intentionally for commercial use (e.g., in cosmetics).
- Industrial and Consumer Products: Microbeads in cosmetics, synthetic textiles, and cleaning agents.
- Breakdown of Plastics: Plastic bags, bottles, and other packaging.
- Industrial Waste: Tire abrasion and paint particles.
- Marine and Terrestrial Sources: Fishing gear and agricultural films.
Impact
- Environmental
- Ingestion by marine organisms disrupts ecosystems. (Biomagnification)
- Accumulates in soil and water, reducing fertility and contaminating drinking water.
- Airborne microplastics contribute to air pollution.
- Health
- Linked to respiratory and endocrine disruptions.
