@Quamera; toxins are concentrated up the food chain.
As a general rule, eating fresh fruit and vegies is relatively low risk unless the soil they're grown in is contaminated - with lead for example.
Decades ago researchers identified DDT as the major cause for the impending extinction of American bald eagles - concentrated up the food chain into a high level predator.
Ocean and river bottom filter-feeders including abalone and oysters concentrate toxins if they're environments are contaminated. Whatever eats contaminated oysters and abalone is ingesting toxins.
People are atop every food chain - it should come as no surprise that nanoplastics are accumulating in human bodies.
But there's more - wrapping food in plastics, plastic containers, plastic seats, airborne plastic particles all find their way into human bloodstreams.
