This plastic pollution comes from "microplastics" – particles smaller than five millimeters – that penetrate our food, drinking water and even into the air.
Worldwide, people average about 2,000 microparticles per week, according to a study by the University of Newcastle, Australia.
These small particles can come from a variety of sources, including artificial clothing fibers, microspheres found in some toothpastes, or larger pieces of plastic that are gradually increasing. break into smaller pieces when you throw them out and expose them to elements.
They pierce our way in our rivers and oceans and can be eaten by fish and other marine animals that end as part from the food chain.
"It is very clear that the issue of microplastics is global, even if the parties clear their backyard, it does not mean they will be safe, as these particles can come from other sources," she said.
The largest source of plastic uptake is drinking water, according to a study that examines 52 existing studies to assess the absorption of plastic around the world.
The study was commissioned by the World Wildlife Fund (WWF) for his report, "There is no plastic in nature: an assessment of plastic ingestion by the nature of humans."
It was found that the average person consumes 1769 plastic particles each week only by drinking water bottled or tapped, but there may be large regional variations. in the United States and India than in European or Indonesian tap water
Shellfish is a source of plastic uptake, with the average person consuming up to 182 microparticles – 0.5 grams – than that per week. The report says that this is due to the fact that "shells are consumed whole, including their digestive system after life in plastic contaminated seas."
Although microplasms have been found in the air, the study says that inhalation is an insignificant intake, but can vary greatly depending on the environment. "
Researchers note that their research is based on a limited set of evidence and comes with limitations, "including" a lack of available data on important indicators, such as weight distribution and size of microplasma in the natural environment. "
