What scientists have learned from 20 years of microplastics research

Summary

Over the past 20 years, microplastics have been found in virtually every ecosystem, including the human body, with growing concerns about their potential harm. A new review of research synthesizes findings about microplastics’ widespread presence and their potential links to health issues such as inflammation and cancer. The particles come from various sources, including the breakdown of larger plastics, synthetic textiles, and tires. Despite technological advances in identifying microplastics, regulatory solutions have lagged. Experts advocate for global measures to reduce plastic production, including a United Nations treaty aimed at curbing plastic pollution.
