Which of the following is NOT one of the main routes of entry for pesticides into the body?

• A. Inhalation
• B. Dermal absorption
• C. Ingestion
• D. Intravenous injection

Answer: (D)

Pesticides typically enter the body through three main routes: inhalation, dermal absorption, and ingestion. Inhalation occurs when aerosols or vapors are breathed in during mixing, loading, or application. Dermal absorption happens when skin comes into contact with pesticides, allowing the chemical to pass through the skin and into the bloodstream. Ingestion can occur if residues are on hands or contaminated food or water are swallowed. Intravenous injection is not a standard exposure route in ordinary pesticide handling; it would require directly injecting the chemical into the bloodstream and is not considered a primary pathway in safety guidance.
