You forgot rain. Maybe one day people will remember we're just sharing one small planet, the air, the water, the food supplies, ... all the shit you dump/burn ends up in your food or water eventually

Why cant we have parallel lines that intersect. Geometry.
The sources cited includes https://doi.org/10.1016/j.watres.2020.116685, which is paywalled, but the snippet of the conclusion that is shown indicates that a possible major cause is industrial emissions:
> As local sources were determined to be significant, the results imply that local action can have an impact on PFAS contamination in precipitation. A three-way ANOVA model determined that functional group, chain length, and location were significant predictors of PFAS concentrations
If you can get the full text I'd be very interested in reading about it.

> n Figure 1B, the levels of PFOS in rainwater are shown to often exceed the US EPA drinking water health advisory for PFOS, except for two studies conducted in remote regions (in Tibet and Antarctica).
I don't think there are a lot of industrial emissions in Antarctica.

That paper alone has 61 references. There are plenty of papers to go read.
but most that shit doesn't survive the journey intact, being out in the elements and bombarded by the sun isn't kind to most things
hence the focus on "forever chemicals"
PFAS are a problem, co2 is a problem, but we have dozens of other very big problems that are partially, if not entirely, obscured
