In 11 out of 13 people sampled, a total of 39 microplastics were found in all regions of the lung.
"We've choked this planet with plastic, from the highest mountains to the deepest oceans—and we've no idea at all about costs for public health," said a British lawmaker.
Our addiction to plastic is having negative effects all along the food chain.
The research comes on the heels of other recent studies showing microplastics having a negative impact on human cells.
The study found that in slow-flowing stream headwaters—often located in remote, biodiverse regions—microplastics accumulated quicker and stayed longer than in faster flowing stretches of river.
How did these tiny pieces of plastic managed to make such a journey?
“This study provides evidence that we are indeed ingesting microplastics.”
The protocol acknowledges that because "microplastics smaller than [one millimeter] in size (such as microbeads) are more difficult to find... more sophisticated technology is required to conclusively identify them."
We highlight just how widespread microplastic pollution is and the potential it has to influence climate on a global scale.
“Unfortunately, with the modern lifestyle, babies are exposed to so many different things for which we don't know what kind of effect they can have later in their life.”
