    Arsenic: 4. What happens to arsenic in the body?

    When arsenic is inhaled due to its presence in airborne particles, the amount absorbed into the blood stream depends on two things – how soluble the particular form of arsenic is and how small the particles are. This said, most arsenic in the body comes from the diet. In the gut, soluble arsenic compounds present in food are rapidly absorbed into the blood stream.
