What are Microplastics?

Microplastics enter the environment through a variety of sources, including degraded plastic waste, synthetic textiles, personal care products, and industrial processes. They can be categorized as primary microplastics (manufactured small particles) or secondary microplastics (fragments from larger plastic items). Microplastics are a growing concern because they are widely dispersed, difficult to remove, and may accumulate in the food chain. Understanding microplastics helps researchers, policymakers, and the public address pollution and advance strategies for plastic reduction and sustainable material management.
