In regards to humans, progress is being made. In coming years, expect greater clarity about effects on our bodies such as:

inflammation

oxidative stress (an imbalance of free radicals and antioxidants that damages cells)

immune responses

genotoxicity – damage to the genetic information in a cell that causes mutations, which can lead to cancer.

TL;DR yes, cancer. It also fucks with wildlife (blocking intestines, giving off poison)

Good chance it probably is, possibly increase chance for asthma, chance for heart attack, another is it probably makes us infertile probably a good thing depending how you think of it.
