**This is fake, not peer reviewed and an attempt to sell a fake cure by a quack. **
If this gives off Andrew Wakefield vibes to you, you are not alone. The "journal" is a huge red flag since the homepage is full of blatantly AI generated images (see below). It appears to have published very little else and appears to have been set up by the second name on the paper and corresponding author, Haitham Amal.
Amal, looking at his LinkedIn, appears to have also recently been appointed to the position at Neuro-nos, a company that describes itself as developing a non-FDA medical cure for autism and dementia.
I'm absolutely not saying that it can't be the case, nor that reducing pollutants from cars (and making more of them) would benefit everyones health. Just in this case, it is a blatant scam that will likely end up subjecting autistic children to god knows what side effects so this guy and his friends can make more money.
If you don't already know of a sufficient number of people doing black bloc, go with grey bloc. By that I mean dull clothes, able to blend in, cap and a face mask, ideally something you wouldn't usually wear. If cops spot someone in a bally and ski goggles, not in a group, before things get too heated, a snatch squad will fly towards you before you know what hits you.
