Very nice. Who doesn't love the taste of plastic?

Plant leaves absorbed microplastics and nanoplastics directly from the air, with the particles subsequently entering the food chain through herbivores and crops consumed by humans, a new study found.
Microplastics are defined as plastic particles measuring up to 5 millimeters in diameter, while nanoplastics are even smaller, less than 1,000 nanometers.
“Once inside the leaf, microplastics move through spaces between plant cells and can also accumulate inside tiny hair-like structures, called trichomes, on the surface of leaves,” said an article explaining the research.
The study also found that microplastics could travel through the plant’s water and nutrient transport systems to reach other tissues. However, trichomes that are hair-like appendages on cells acted as ‘sinks’ that trapped external particles, thereby limiting the transport of plastics from leaves to roots.
“Given that leaves are a key part of the food chain, microplastic particles that accumulate here can easily pass to herbivores and crop leaves, both of which can be directly consumed by humans,” the article noted.
