you touched on a teeny bit? When you're kind of going over the definitions? But I think it'd be helpful to just dive into it a little deeper, which is how our human. Ins being exposed to microplastics currently we

should always be thinking about this through the lens of relevant versus not so relevant exposure. But again we're going to always try to focus on a relevant exposure which is an exposure that has the potential to accumulate. So the most common route of human exposure is from inhaling, plastic, dust, and fibers and from consuming food and beverages that contain these micro Nano Plastics. And again, that's why I prefer to talk about en MPS rather than just Micro Plastics. Why? Because my concern, about consuming a 5 mm piece of plastic is nil because it can't be absorbed it's going to come right out my body. The next day, this is not the thing that we need to be afraid of. So what are the foods and beverages? We need to be concerned with the highest places. We tend to see these are in Seafood. Salts water. Both tap water and bottled water but also in fruits, vegetables, Meats. Even beverages like milk beer and wine which obviously are contain water as well. Nano Plastics in soil can accumulate within plants and obviously the exposure gets magnified as you go up. The food chain, this again explains why we would see it in Seafood. Given that, we understand the role of Plastics in the oceans. And that's why obviously, you can see seafood and land animals accumulating, these as well. The epithelial barrier is the first line of defense. Remember, there's an epithelial layer on the outside of your body. Eat that we can see. But there's also an epithelial layer on the inside of your body, everything between your mouth and your (expletive) is also an epithelial layer and that's why generally micro Nano particles. Don't enter the body through the skin or through the gut unless they are small enough. We've already talked about it. The pulmonary, epithelium requires them to be smaller than 2.5 microns and in the lining of the gut, it could probably be as big as 150. Ron's to be absorbed.
