With that in the background, I'm struggling to distill this article into a "so what". The article suggests the EPA limit is one incidence of cancer in a million people per lifetime. If they've underestimated the risk from formaldeyhyde by one or two orders of magnitude I'm still not seeing what the problem here is. Odds of prostate cancer in men is double digits over a lifetime. This seems like something of a non-issue. If anything, if formaldehyde is industrially useful, the EPA is probably doing the right thing bending the rules. We literally don't know how to sustain modern society without some deaths from industrial processes.
