Chronic poisoning refers to poisoning that occurs due to what?

• A. Repeated exposures to pesticides over a period of time
• B. Single exposure only
• C. Acute high-dose ingestion
• D. Exposure to sunlight while pesticide is present

Answer: (A)

Chronic poisoning comes from ongoing, long-term exposure to a toxic substance, often at low levels, so the total amount builds up in the body over weeks, months, or years. Because the dose accumulates gradually, the health effects appear slowly and may be nonspecific, making them harder to link to the exposure. This is why repeated exposures to pesticides over a period of time best describe chronic poisoning. In contrast, a single exposure typically leads to acute poisoning, with rapid or immediate symptoms after one event. The idea of being exposed to sunlight while the pesticide is present isn’t the mechanism for chronic toxicity; it doesn’t capture the idea of accumulation from repeated contact.
