Dietary and inhalation exposure to nano- and microplastic particles and potential implications for human health
World Health Organization (2022). WHO report (ISBN 9789240054608).
What they found
WHO reviewed studies up to December 2021 on micro- and nanoplastics in food, drinking water and air. It found the available data were of only very limited use for assessing risk, because toxicity studies used doses and particle types that do not match real exposure, so no quantitative risk assessment was possible.
- What it can't tell you
- Literature cut-off of December 2021, before the blood, plaque, brain and testis studies. A data-quality review, not a finding of safety or harm.
