Unusual carcinogens
There was a recent news report that stated that diesel (fumes? exhaust particulates?) cause cancer.
I didn't see anything about how much is required and what the risk is over what length of time.
Linked was a PDF which detailed other substances caused (group 1), probably caused (2a), or possibly caused cancer (2b).
In group 1 (causes cancer) were some expected substances: Plutonium, radium, ultra-violet light, X-rays, and lots of nasty looking chemical substances which I haven't heard of, such as Diethylstilbestrol, 2,3,4,7,8-Pentachlorodibenzofuran, and others.
Alcohol, and tobacco were group 1 too.
However, there were a few substances which surprised me:
- Leather dust
- Ocupational exposure as a painter
- Salted fish, Chinese style
- Soot
- Wood dust
(I've just looked at that PDF again (to write this) and it looks like diesel is now in group 2a, so I'm not sure what's going on. The BBC report says "Diesel exhausts are now in the same group as carcinogens ranging from wood chippings to plutonium and sunlight to alcohol", which it doesn't appear to be.)
