I think what was determined is that the way the chemical were being used and handled was not dangerous to workers. As unpleasant as both chemicals are, they can be used safely with proper precautions. There is however a pretty big expense associated with their use due to the hazards both human and environmental. No one is going to magically discover that benzene is not a carcinogen or that hexane doesn't destroy testicular tissue. That is long settled information.
