We swallow 5gram plastic a week
Human ingestion and inhalation of plastic particles has been proven, but for the first time researchers have been able to accurately quantify the extent of the phenomenon. And that’s not really reassuring …
An average person could ingest up to 5 grams ofeach week, the weight of a credit card, according to a report commissioned by the at Newcastle University (Australia), and published Tuesday.
According to these results, a compilation of 50 studies conducted on humanof plastics, each man would swallow about 2,000 microparts and particles each week, or some 250 grams annually.
Studies have previously shown that humans ingest and breathe a swarm ofparticles each year, but the challenge for Australian researchers was to weigh their weight.
” As awareness grows about the existence ofand their , this study provides for the first time an accurate calculation of intake rates ,” said Thava Palanisami, a university professor. from Newcastle. This will help identify potential toxicological risks for humans . “
Bottled water, seafood,beer and salt on the front line
First source of this ingurgitated, water, especially if it is bottled. Of the other consumer products analyzed, seafood, beer and salt contain the highest rate.
According to a Canadian study published on June 5, based on the lifestyle of an average American, an adult ingests up to 52,000 microparticles ofa year, to which are added 90,000 additional if he drinks only (and 4.000 if it is satisfied with tap water).
And if we take into account the, and therefore the , this figure increases to 121,000 – these estimates vary individually according to the mode and the place of life, Environmental Science and Technology .
For WWF, ” it’s a wake-up call for governments: plastics do not just pollute our, they do not just kill marine life, but they are in all of us, ” says Marco.
Lambertini, Director General of WWF International, in a. ” While research is studying the potential negative effects of plastic on human health, it is clear that it is a global problem that can be solved only if we tackle the roots of pollution: if we do not want of plastic in our body, we must stop the millions of tons that continue to fail in nature every year, “he added.
He called for action at the level of governments, businesses, consumers “ and to find ” a global treaty “against ocean pollution, with national goals.
Microplastics, coming from the degradation of products as diverse as synthetic garments,, …, are now found everywhere on the planet, on the highest as in marine .
