Chemical Effects

The effects chemicals have on the various organs of the human body depend on several important factors:

• The form of the chemical: Is the chemical a solid, liquid, or gas?
• The route of entry, or how the chemical contacts the body: is it ingested, inhaled, absorbed or injected?
• The dose, or amount, the body receives: How much chemical makes its way into the body?
• The toxicity: How poisonous is the chemical?
