I rememeber something from my college chemistry class that stated that
"toxic" has to do with the level or amount of a particular chemical, not
the chemical itself, i.e., a chemical isn't by definition toxic. What was
stresses was that there are toxic levels for a chemical. Even pure oxogen
is lethal if breathed in over one atomospere of pressure. Maybe this
explains why people react so differently to the same exposure to a certain
chemical or substance.
I sure hope my chemistry professor is not rolling over in his grave...
