A Biomarker for 1,3 Butadiene in Brain Cancer?

Or would a better title be something like "Back to the Future"? When I got out of law school I worked on more PAHs, nitrosamine and butadiene cases than dust cases. Some early and fairly primitive epi studies had suggested causal associations with brain cancers in southeast Texas but the litigation never really went anywhere - or at least it didn't turn into the next asbestos. There were a few bladder cancer cases that got interesting but the literature on glioblastoma pretty uniformly concluded that it had no known etiology and the brain cancer cases died out.

See: Human exposure to selected animal neurocarcinogens: a biomarker-based assessment and implications for brain tumor epidemiology. You'll have to register (and pay) to get more than the abstract.
