Where does the 5g come from? And, whats the distribution by economy and class, and by other dietary habits..<p>I mean sure: if there is some plastic leaching from tins, I get that. If the PET bottle my milk comes in leaches, I get that. But I eat a lot of fresh fruit and we bake our own bread. If the model assumes tinned fruit and package bread, without more information how can I assess my personal exposure?<p>How does tap water reduce 90k from bottled water to only 40k particle exposure? Whats the path of microplastics in the water supply? Did this assume everyone keeps tap water in plastic filter jugs? or that the water supply is plastic pipes and not copper or iron or ..<p>Again.. How much is this specific to a regime of water treatment in one economy?<p>I can believe this, if I get better evidence for this.
