Health effects of ingestion of microplastics via food, water and breathing still unknown.
The average person eats at least 50,000 particles of microplastic a year and breathes in a similar quantity, according to the first study to estimate human ingestion of plastic pollution.
The true number is likely to be many times higher, as only a small number of foods and drinks have been analysed for plastic contamination. The scientists reported that drinking a lot of bottled water drastically increased the particles consumed.
The health impacts of ingesting microplastic are unknown, but they could release toxic substances. Some pieces are small enough to penetrate human tissues, where they could trigger immune reactions.
Microplastic pollution is mostly created by the disintegration of plastic litter and appears to be ubiquitous across the planet. Researchers find microplastics everywhere they look; in the air, soil, rivers and the deepest oceans around the world.
Some of the best available data is on water, with bottled water containing 22 times more microplastic than tap water on average. A person who only drank bottled water would consume 130,000 particles per year from that source alone, the researchers said, compared with 4,000 from tap water.
Cox was clear that there are no known health effects as yet, but he said the ingested particles are "a high exposure risk in terms of numbers. It could be a potential alarm call for sure".
This could explain some medical issues but we don't know anything yet. Hopefully when we find out more this will lead to more regulation on how plastics are used. Maybe this will lead to more resources being used to properly dispose of garbage.
I guess I'm avoiding bottled water and soda until they figure out what these plastic particles do to the human body.
