In the shadowy underworld of soil, tiny plastic particles are lurking like molecular saboteurs. Many experiments use hydroponic setups where seedlings are dunked into water with plastic particles, letting leaves and stems touch the mix directly. So that complicates the results, with critics claiming the plastic particles ultimately detected are just clinging to the surface like glitter on a party guest? Researchers discovered that about 5% of the tiny plastic particles stuck to or were absorbed by the thin, non-edible roots of radishes. These findings suggest that tiny plastic particles can hypothetically end up in parts of plants we eat.
