To what extent does using plastic cooking implements (both spatulas, spoons etc and Teflon pans) increase dietary exposure to microplastics?
gpt
When you eat from a plastic container you abrade it and injest particles, but these particles.are fairly large, say 10um to 1 mm. They are far too large to cross cellular membranes, and pretty inert, so they should just pass on through. The more serious issue is plastic nano particles which are 1nm to 1um and are formed from repeated abrasion of micro plastics. These can be systemically absorbed. Effects are still largely unknown.
