“Quantification suggests more than 10^5 particles in each liter of bottled water, the majority of which are nanoplastics” “nanoplastics are believed to be more toxic since their smaller size renders them much more amenable, compared to microplastics, to enter the human body” 😬

Consider switching to glass bottles for drinking liquids. https://www.pnas.org/doi/10.1073/pnas.2300582121

I think humans are pretty ignorant when it comes to how things affect our health, especially when these things are happening at such small scales. 100k every litre ? A litre a day would be 36,500,000 particles a year. What if it accumulates? Not going to discount it 🤔
36M sounds like a big number, but the nanoscale is extremely small so the total mass will be mind-numbingly low. You can easily do the calculation assuming 500 nm particle diameter. V=(4/3)pi r^3 and m = dv are the only equations you’ll need. The density of plastics is about 0.9
Of course, there's about 10^23 molecules in a litre of water; 10^5 particles may not represent very much. A litre of water probably contains a few orders of magnitude more of radioactive particles. The plastic may be insignificant.
yeah it comes down to just how toxic they can be. maybe they just bounce around and get flushed out eventually, or stay around and disrupt things? biology is absolutely insane once you start going down that rabbit hole. So much systems complexity. Hard to wrap the mind around it all.
Nanoplastics act as focal points for hydrophobic protein aggregation which is likely to have impacts in many chronic disease conditions—kidney dysfunction, blood/brain barrier dysfunction, digestive duct blockages, peripheral nerve neuropathy (myelin sheath inflammation), …. In addition many cell types require adhesion to regulate normal behavior and they undergo apoptosis when free floating. So streaming non digestible adhesive islands traversing your body could certainly create a permissive setting for persistent inflammation and earlier stage metastases. Simply, don’t.

How do the nano plastic particles get into water? Is it during manufacture of plastic bottles or just the wall of plastic bottles start to decay and get into the water?
I thought they did. I hope not. The frivolous complaints about them being pesticides are probably backed by bottled water company lobbyists inside the EPA. We love our berkey.
Was just on an island in “paradise” and the amount of plastic trash that regularly washed up was mind boggling. Definitely made me wish plastic was never invented
