Isuppose you’re right that there is not a strict definition but I’ve never spoken with person that didn’t understand microplastics to mean something like:
micro particles
(too small for a person to notice ingesting but visible with a magnifying glass or optical microscope) ::: of [solid but easily deformable] hydrocarbon polymers [intended] to be biochemically inert/benign.
Health agencies have historically adjudicated whether particular hydrocarbon polymers are safe for human exposure based on biochemistry (ie are they poisonous?). Assuming that if they were biochemically inert they’re safe. But obviously it’s unsafe to fill your lungs with inert particles of any size… you’ll suffocate. So is it a problem that our blood has unprecedented levels of inert micro particles? It’s probably not good. How much can a person ingest before serious issues?
Nobody really knows. Maybe microplastics cause autism, I don’t think anybody knows. We’ll probably have to do some heinous animal trials to figure it out. And look how much time I’ve spent talking about something other than climate change.
The issue is that “microplastics scare” is basically a fucking religion right now. There’s no evidence nor is there any consistency in testing.
We already know that small particles entering our lungs is bad (see PM2.5 and PM10 studies). So whatevers man. Except the main things that makes PM2.5 or PM10 is burning food, smoked foods, gasoline / diesel engines, and vehicular emissions.
The minute you start talking about the fucking plastic cutting board (HDPE) or the Tupperware (Usually #5 plastic, polypropylene a totally different chemical) and we’re talking about numbers far far, far smaller than PM2.5 or PM10 or other such pollutants that we’re actually worried about right now.
Do you really think a meme comparing lol Lead and Asbestos to lol “microplastics” is relevant? Or discussion worthy?
I agree with you that it’s not a major concern and is a fad/ panic. We don’t know what the effects are because they are undetectable. I think it’s maybe boosted by people that want to keep the green minded people spinning their wheels instead of making progress on climate change.
My point about the lungs was just that if something is inert it doesn’t really matter what chemical it is, but it could still be harmful. I’m trying to show that I’m open minded to the harms of micro plastics but still wholly unconvinced that microplastics are worth even a fraction of the attention they’re getting.
