Microplastics are tiny pieces of plastic which can get into our bodies through our food, drinks, or even the air that we breathe. Although scientists are not yet sure what is the effect of these compounds on human health, increasingly more studies have provided clear evidence that exposure to microplastics can lead to oxidative stress, inflammation, and even DNA damage.

A research team led by Sichuan University in China has now found that drinking a single cup of takeaway coffee per week could expose a person to over 90,000 microplastic particles each year.

The scientists examined three different types of plastic cups in which takeaway coffee is usually served: polypropylene (PP), polyethylene terephthalate (PET), and polyethylene (PE). They filled each of the three kinds of cups with 400 milliliters of water, sealed them with foil to avoid airborne microplastics entering the cups, and shook them for one minute. These procedures were carried out on a clean glass beaker, in order to avoid potential procedural contaminations.
