Humans consume ‘tens of thousands’ of plastic particles each year

Humans eat and breathe in tens of thousands of microplastic particles every year, according to a new analysis that raises fresh questions over how plastic waste could directly affect our health.

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. An additional 90,000 particles could be ingested each year if an individual only drank bottled water, according to the study, published in the journal Environmental Science and Technology.

Grant, who was not involved in the research, added that it was likely that only a small percentage of particles inhaled actually reached the lungs.
