"Researchers at the University of Plymouth found that particles found in the soil can be absorbed into the edible parts of crops during the growing process. Nanoplastics measuring as little as one millionth of a centimetre in diameter were found in radishes. And for the first time, experts found that these plastics can enter through the roots and spread through the plant as they are so small."
"Lecturer in physiology Dr Nathaniel Clark said: Plants have a layer within their roots called a Casparian strip, which should act as a form of filter against particles, many of which can be harmful. But he warned that nanoplastic particles can get beyond that barrier and be passed on to humans when the vegetable is consumed."
Researchers at the University of Plymouth found soil nanoplastics can be absorbed into the edible parts of crops during growth. Nanoplastics as small as one millionth of a centimetre in diameter were detected inside radishes. For the first time, the plastics were observed entering through roots and spreading through the plant. A Casparian strip in roots normally filters harmful particles, but nanoplastics can cross that barrier and reach humans when vegetables are eaten. The evidence suggests nanoplastic uptake may affect multiple types of produce, raising concerns about widespread human exposure via food.
