At least in England, Benzene |= Benzine. Benzene is C6H6, the simplest aromatic compound. Benzine is a mixture of hyrdrocarbons, I think obtained for the distillation of crude oil. I suspect in a lot of cases the carcinogenic risk is massively overstated. It's probably a problem if you work with the stuff all day every day, in large quantities. It's probably much less of a problem (if a problem at all), if you use a little from time to time. I've been told by somebody who darn well ought to know, for example, that PCBs (polychorinated biphneyls, not circuit boards) probably are harmful if you work every day on large power transformers. But the amount contained in one high voltage capacitor is not going to kill you unless you are really stupid with it. Anyway, smoking is almost certainly more harmful than any of these substances i nthe quanties they are likely to be used here, and I don't smoke so I'll take the risk in other ways... -tony (it's a well known fact that research causes cancer in rats)
