Paracelsus Quotes
The dose makes the poison.
This scientific quotation is politically important because it defines the difficult problem of setting acceptable and safe environmental and work standards for air or water quality and contact with potentially toxic substances. As this quotation illustrates, everything is toxic if given in large enough doses. Table salt can kill a human if enough if ingested. Tiny amounts of even a poison will do no harm. What makes setting of standards still more complicated is that human beings differ in the amount of a substance it would take to produce a toxic reaction. Allergies are the best example, but the variability of sensitivity always exists.
