For many chemicals, the toxic effects occur at the site of absorption. Inhalation exposure- Gases, vapors, airborne powders, and aerosolized liquids are inhalation risks.

   How are toxic chemicals grouped?

   • Toxic chemicals can often be grouped into classes, whereby all the chemicals in a given class cause similar human health effects. These constellations of toxic effects or toxic syndromes comprise a set of clinical "fingerprints" for groups of toxins. All of the toxins associated with a given toxic syndrome are treated similarly.
