Yah, that's the sad part of all of this. A lot like smoking
cigarettes I suppose. I'm young and have had the benefit of years of
peoples experience with these chemicals. Unfortunately this
information has come pretty late for those who worked with it over
the years.
That said, there are very effective solvents out there that are not
nearly as toxic. Probably not as good as the the most potent ones we
have described here, but that is almost certainly what makes them so
unhealthy at the same time.
A very common, widely used solvent in the lab is Acetone. This does a
great job of solvating, and need only be treated respectively in the
presence of open flame and in the absence of adequate ventilation.
Benzene has all but disappeared from the market. It was a great
solvent, only its toxicity is off the charts.
