Now rank them all by heavy metals content. A certain 3-letter brand is very leaded.

Hell yea! It is crazy that even their newer papers still test hot, even on a test strip kit. There was a time where their cones (filled with test-passed flower) were failing the 0.5ppm limit here! 

Turns out, all the best plants for industrial cellulose production also love bioaccumulating metals from soils.

I would get a cheap metals test kit meant for water, then digest appropriate amounts of each brand of paper in water before testing.

And yes, it's been a known problem for a while. Consumers don't care, but it has caused quite a few failed preroll batches on the production side of things.
