I have this product called "Krylon - Contractor grade lubricant" it's essentially just micronized Teflon used as lubricant... should I not be using this stuff?...
As long as you're not ingesting it and use proper masking then you should be fine from my understanding. If I remember correctly the main issue with Teflon was how often it was used in pots and pans.
Mix that with improper use, and it can cause flaking of the Teflon. Things like stirring with metal utensils instead of wooden ones lead to many people ingesting a lot of the stuff.
Edit: realized it can be aerosolized and added that use of a face mask would likely help any additional problem brought on by that.
Honestly I think that were a little overly concerned about microplastics since if it were truly poisonous you would hear about plastic poisoning in the news hundreds of times a day. My parents chain smoked their whole life absolutely full of carcinogens way worse than microplastics for decades and they are still kicking in their mid 60s today. The human body under normal circumstances is ridiculously resistant
It could be cancer that takes years to develop. Most things like that like asbestos, lead, etc... take a long time to be detected/ figure out how they're damaging the body. Even once they are, you can't prove that's what caused it without scientific testing/ statistics.
Microplastics can act as carriers of other environmental toxins, such as PS, and exposure to high concentrations of PS are detrimental to human lung cells, increasing the risk of chronic obstructive pulmonary disease.
We know cigarettes cause cancer, sure. Maybe people didn't know long ago, but you could always choose whether or not to smoke them. Even when smoking was rampant, there were always those that just didn't want to, whether or not they could tell its effects.
I can't choose whether or not to have microplastics in my blood so I try not to worry about whether or not it will affect me.
There are so many things in this world that we can choose that it doesn't really make sense worrying about what we can't.
