Studies have previously shown that humans ingest and breathe in a swarm of plastic particles every year, but the challenge for Australian researchers was to assess the weight.
“As awareness grows about the existence of microplastics and their impact on the environment, this study provides for the first time an accurate calculation of ingestion rates,” explained Thava Palanisami, professor at the Newcastle University. This "will help to identify the potential toxicological risks for humans".
Bottled water
First source of this ingested plastic, water, especially if it is bottled. Among the other consumer products analyzed, seafood, beer and salt contain the highest levels.
According to a Canadian study published on June 5, based on the lifestyle of an average American, an adult ingests up to 52 micro-particles of plastic per year, to which are added an additional 000 if they drink. only bottled water and 90 if he is content with tap water.
And if we take into account air pollution, and therefore inhalation, this figure rises to 121, these estimates varying individually according to the mode and place of life, added this study published in the journal Environmental. Science and Technology.
For the WWF, "this is a wake-up call for governments. Plastics are not just polluting our rivers and oceans. They are not only killing marine life, but they are in all of us", underlines Marco Lambertini, chief executive of WWF International, in a statement.
Microplastics, coming from the degradation of products as diverse as synthetic clothing, tires, contact lenses, are now found everywhere on the planet, from the highest glaciers to marine faults.
