The environment is polluted by microplastics worldwide.
The environment is polluted by microplastics worldwide. The tiny particles enter food chains, and thereby the digestive systems of animals and humans; moreover, they can be inhaled. Instead of being excreted, small microplastics can be incorporated into the body tissue. A research team at the University of Bayreuth has now discovered that microplastic particles find their way into living cells more easily if they were exposed to natural aquatic environments, i.e. fresh water and seawater. Biomolecules occurring in the water are deposited on the microplastic surfaces, which promote the internalization of the particles into cells. The researchers have presented their results in the journal "Science Advances".
