Briefings

A 2026 article argues that plastic fragments into micro- and nanoparticles, which drastically increases surface area relative to volume. This exposure makes the material chemically active rather than inert, potentially causing biological harm. The evidence highlights that while plastics are used for packaging and toys, the fragmentation process is the critical factor for toxicity.

Key points

• Plastic fragments into micro- and nanoparticles, causing surface area to increase dramatically relative to volume.
• Increased surface area exposes vast amounts of material to surroundings, making plastics chemically active instead of inert.

Context and limitations

Evidence is limited to a single 2026 article; no experimental data, biological studies, or causal mechanisms are provided.
