Which item is NOT a route by which pesticides can enter the body?

• A. Inhalation
• B. Dermal absorption
• C. UV exposure
• D. Ingestion

Answer: (C)

Pesticide exposure enters the body mainly through three pathways: inhalation, through the skin (dermal absorption), and ingestion. Inhalation happens when pesticide particles, vapors, or aerosols are breathed in. Dermal absorption occurs when the skin comes into contact with pesticides and the chemical passes through into the bloodstream, especially if skin is wet, damaged, or the product is formulated to be readily absorbed. Ingestion occurs when residues are swallowed, often via hand-to-mouth contact or contaminated food or drink. UV exposure is not a route for a pesticide to enter the body. Ultraviolet light is energy from the sun or other sources; it can interact with some chemicals on the skin to cause phototoxic reactions or degrade the pesticide, but it does not transport the chemical into the bloodstream or internal tissues. Therefore, it is not a pathway for entry, making it the correct choice for what is NOT a route of entry.
