Gino and Chimera,
I can't let some of your statements about carelessness with chemicals go unchallenged. I remember hearing similar things back in the '50s, about chemicals now considered so dangerous it is almost impossible to obtain them, even for research purposes.
The effect of long term exposure to low level doses of toxic chemicals is generally poorly known—it takes too long to study, even in lab rats. The cumulative effect of exposure to multiple chemicals is essentially unknown. Most of these chemicals have to be metabolized in the liver. This may harm the liver, and sometimes the metabolites are more harmful than the originals. You cannot live without a liver, and dying from liver disease is slow and painful poisoning. Emphysima is no fun, either. The rates for both are rising, just as for cancer.
The attitude that because something does not do immediate, serious damage it is nothing to be considered, is dangerous and irresponsible. That is, as I'm sure you will vociferously agree, your choice. But don't urge it on others.
On the other hand, and this may be what you are really trying to say, the constant media hype has created a climate of paranoid fear about the issue. That is also foolish.
Used carefully and responsibly, the danger to the hobbyist is very small.
