IARC—review ongoingcausal evidence insufficient

Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.

Where you encounter microplastics

  • Consumer Products — Plastic bottles and containers, Food packaging, Plastic toys and household items
  • Drinking Water — Leaching from plastic pipes, Migration from bottled water containers
  • Indoor Environments — Off-gassing from plastic furniture, Degradation of plastic products

Safer alternatives

Lower-risk approaches that achieve a similar outcome to Microplastics:

  • NSF-certified activated carbon filtration
    Trade-offs: Does not remove all contaminants. Requires filter replacement.
    Relative cost: 2-5× conventional
