If there is so much of them maybe link a few, with most significant results? I think general audience is a bit de-sanitized to "X impact on Y" research after drinking coffee was shown to do literally everything, thanks to studies with tiny participants count and widespread p-hacking.

BTW how do you even find control group when micro-plastics are already everywhere?

I avoided linking examples because a skeptic will always find faults in cherry picked examples. I encourage you to read a few studies with an open mind and draw your own conclusion. Many of these studies I've seen do address your concerns around control groups.
