The WHO has recently published a document containing “a summary of the evidence, key findings, recommendations and research needs” with regards to the presence and potential human health impact of microplastics in treated tap/ bottled water. Using the data available, the WHO concluded that there was no reliable information to suggest that toxicity relating to the physical hazard of plastic particles is a concern; it considered there to be “a low health concern for chemicals associated with microplastics”. That said, they then asked for “future research and emerging science to address data gaps” to allow for “more accurate and reliable assessments of exposure and potential impacts to human health” in the future.
