Human health risk from a slightly toxic pesticide is increased by which?

• A. Using less product
• B. Repeated exposure
• C. More PPE
• D. None of the above

Answer: (B)

Repeated exposure raises health risk because every contact adds to the total amount of pesticide that can be absorbed by the body. Even if a single exposure is only mildly harmful, the body’s burden accumulates with each additional exposure, and the cumulative dose can reach levels that cause adverse effects. Pesticides can enter through skin contact, inhalation, or ingestion, so frequent handling increases the likelihood of harmful buildup. In contrast, using less product or wearing more PPE would reduce, not increase, exposure, and saying none of the above doesn’t fit since cumulative exposure clearly raises risk.
