HUMAN TOXICOLOGY II
• Some important toxicological variables:
  1) Concentration of chemical
  2) Duration of exposure per incident
  3) Frequency of exposure
  4) Rate of toxicant input per incident
  5) Total exposure time
• The chemical will need to bypass the body’s natural defense systems to enter the
blood & lymph system which will widely
disperse the toxicant.
