List and define the four common routes of entry for individual environmental factors.

-   Inhalation: inhaling agents directly into the respiratory tract and lungs
-   Absorption: refers to entrance through the skin, regardless of whether the skin is intact or damaged. Some substances may be absorbed by way of openings or through hair follicles, while others may dissolve in fats and oils of the skin. Some compounds can produce systemic poisoning through direct contact with the skin
-   Injection: can involve accidental or intentional injection of agents from either a high-velocity source or a point source
-   Ingestion: includes knowingly or unknowingly eating or drinking a harmful agent and subsequently having a toxic compound absorbed from the gastrointestinal tract into the bloodstream (page 477)
