Briefings

A 2026 Nature study led by Wei Min at Columbia University found that microplastics are not chemically inert, as they can generate reactive oxygen species (ROS) in water droplets. This process may damage biological molecules like DNA and proteins, though the direct link to human disease remains unproven. The research highlights the chemical activity of microplastics in aquatic environments.

Key points

• Wei Min's team at Columbia University demonstrated that microplastics generate reactive oxygen species (ROS) in water droplets, which can damage DNA and proteins.
• The study suggests microplastics are not chemically inert, potentially causing molecular damage in biological systems.

Context and limitations

The study is still in preprint status and does not confirm whether ROS generation directly causes human disease.
