The World Health Organization (WHO) estimates that current levels of microplastics in drinking water are not yet a health hazard. However, experts remain cautious for the future.
"The risk is low"
In a report released Thursday, WHO presents a synthesis of the latest knowledge on microplastics in tap water and bottled water and its effects on human health. "The key message is to reassure drinking water users around the world: according to this assessment, we believe the risk is low," said the Water, Sanitation, Hygiene and Health Unit's coordinator. WHO, Bruce Gordon, at a press conference.
He said the microplastic health risk analysis focused on three aspects: the risk of ingestion, the chemical risks and the risks associated with the presence of agglomerated bacteria.
Warning for the future
WHO insists that data on the presence of microplastics in drinking water are currently limited, with few reliable studies, and that these are difficult to compare, which makes the analysis more difficult. results. WHO therefore calls on researchers to conduct a more in-depth evaluation, using standardized methods.
The report warns of the dangers ahead: if plastic emissions in the environment continue at the current rate, microplastics could present widespread risks for aquatic ecosystems in a century, which should not be without consequences on human health.
