A recent risk assessment that considered animal data, however, gives a cancer risk estimate for background exposure to dioxin and dioxin-like compounds (e.g. some PCBs) with an upper bound in the range of 10⁻⁴ per year.

Gotta love doctors: 10⁻⁴ per what per year, and how do they define "background" exposure?

Which cancers?

[I have a friend who used to do statistics at Mayo Clinic, poking holes in clinical studies' statistics. He taught me to snark ;-) ]

In the meantime, you may enjoy this, from the (I think) August 1984 Chemical & Engineering News:

A mosquito was heard to complain
'I fear they have addled my brain!
The cause of my sorrow
is para-dichloro-
diphenyl-trichloroethane!'

Cheers!

you know, that stuff was like reading a hybrid of greek and latin. But I just know it said something bad somewhere in there.
