Which is an example of a local effect of pesticide exposure?

• A. Reduced ability of blood to clot
• B. Hormonal effects
• C. Eye irritation or burning
• D. Kidney damage

Answer: (C)

Local effects happen right where the exposure occurs. When pesticide gets into the eye, the tissues there are directly irritated, causing burning, redness, and tearing—these changes happen at the exposure site and don’t require the chemical to travel through the body. Other options describe effects that come from the chemical being absorbed, circulating in the bloodstream, and affecting distant organs. For example, interference with blood’s ability to clot would result from the pesticide acting inside the body, not just at the contact point. Hormonal effects come from disruption of the endocrine system throughout the body, and kidney damage reflects toxicity that has traveled to and affected internal organs. So eye irritation or burning is the clearest local effect.
