Humans eat and breathe in tens of thousands of microplastic particles every year, according to a new analysis Wednesday that raised fresh questions over how plastic waste could directly impact our health, reports AFP.
Microplastics—tiny plastic shards broken down from man-made products such as synthetic clothing, car tyres and contact lenses—are among the most ubiquitous materials on the planet. They have been found on some of the world’s highest glaciers and at the bottom of the deepest ocean trenches. Several previous studies have shown how microplastics may enter the human food chain,including one last year that found them in nearly all major bottled water brands sampled.In Wednesday’s research, Canadian scientists analysed hundreds of data sets on microplastic contamination and compared them to the typical diet and consumption habits of Americans.
They found that an adult male could expect to ingest up to 52,000 microplastic particles each year.
