Glass bottles found to contain more microplastics than plastic bottles

"We expected the opposite result," Ph.D. student Iseline Chaib, who conducted the research, told AFP.
"We then noticed that in the glass, the particles emerging from the samples were the same shape, color and polymer composition—so therefore the same plastic—as the paint on the outside of the caps that seal the glass bottles," she said.
The paint on the caps also had "tiny scratches, invisible to the naked eye, probably due to friction between the caps when there were stored," the agency said in a statement.
This could then "release particles onto the surface of the caps," it added.
OK, so maybe a minor change in how these bottles are filled and sealed could end up fixing the issue. There's clearly some issues with soft drink assembly lines, and if these can be addressed, then the overall amount of microplastics can be mitigated. Seems like we need to start phasing plastics out of every step of manufacturing if we want to end microplastics in food and drink.

If the scratches are invisible to the naked eye, then there is nothing that can be done on the manufacturing line, there is going to be too much random variation to fix that. The option would have to be getting rid of any plastic altogether in the design room, which likely would shorten the length of product shelf life to an unacceptable degree for these products.
-
If this is the same data I saw from another article the researchers showed that cleaning the caps with compressed air before putting them on bottles reduced the plastic by a large margin.

All of these factory spaces have metrology departments for confirming product specifications are in spec, who are likely to have training and expertise in defect isolation (as in finding where a defect is coming from). I have very little doubt that they would be able to create/purchase the necessary tools for checking for microplastic dispersion within the factory floor and isolating the key locations that need fixing. That is, if regulations started requiring and testing for lower microplastic content.

Seems like a decent solution is “Don’t paint the lids”

I'm surprised wine is not contaminated.

I'm sorry but I saw this and just busted out laughing because jesus fucking christ :yea:

Does anyone have a long ass video on what this microplastics shit is? Anytime I hear about it I'm like "ok so what?"
-
I don't have a video, but from what I understand is they are small plastics (as the name suggests) smaller than 1mm. Larger plastics pass through your digestive system and are excreted, but smaller ones can pass into the body's internal bloodstream and accumulate in internal organs.
The body cannot cleanse them as they are inert. Scientists are researching their relationship with degradation of bodily functions resulting in infertility, inflammation and other diseases.
This is an issue that will worsen over time as plastic production continues unabated. Because humans are at the top of the food chain, as plastics accumulate in our environment, they will increase in over time in the foods we consume (bioaccumulation, think of plankton absorbing plastics, that are eaten by krill and build up in the crustacean's body, then the krill is eaten by a minnow and because one minnow eats many krill, the proportion of microplastic increases as you move up the trophic chain. That minnow is eaten by a tuna, that is then eaten by a human. That person human will ingest more microplastics.
This is in addition to the plastic present in water, vegetables and grains through contamination of ground and rain water, which isn't removed by basic water treatment. Or the plastics that fray from synthetic clothing, especially under friction and heat such as during washing, and are inhaled.
Recycling of plastics is also a complete non-starter because the the plastic degrades in quality with each reuse before it joins the rest of the rubbish in landfill.
At what point the quantity of plastics in the brain, in particular, causes it to totally stop working goodness knows. A recent report says that the average USA adult has a plastic spoon (that's the spoon itself, not the measurement of the bowl of the spoon)'s worth of plastics in the brain. The longer you can delay this the better. Probably.
-
My whole thing is, the term “plastic” can refer to a ton of different materials and while most are stable to the point of non-reactivity, most of these materials are essentially organic substances (hydrogen, carbon, oxygen, nitrogen, etc). I never see anyone talk about methods or standard deviations or anything like that it’s just “there’s a spoon in your brain!” Is there? it’s LDPE specifically? Styrene? PVC? what are we talking about?

How. The lid is such a leaker of microplastics that it's worse than the entire rest of the bottle? Genuinely what the fuck.
Is this the little plastic sealer inside the aluminum bottlecap, or for full plastic lids?
It's the paint on the lid, when I first read this report it seems like it was specifically metal lids
