Solvents are compounds that dissolve things. Water is a useful,
life giving solvent. Most other solvents dissolve fats and are
life threatening, because fats form the membrane wall around
each of our cells, especially our nerve cells.
The solvent that does the most harm is benzene. It goes to the
thymus, ruins our immune system, and causes AIDS. The next
worst solvent is propyl alcohol. It goes to the liver and
causes cancer in some distant organ. Other major culprits of
disease are xylene, toluene, wood alcohol, methylene chloride,
and trichloroethane (TCE). I'll discuss each one later, with the
ailment it's associated with.
