Which of the following best describes chronic exposure?

• A. Immediate Severe Poisoning
• B. Single Event Exposure
• C. Repeated Exposure To Low Levels Over A Period Of Time
• D. Acute Poisoning

Answer: (C)

Chronic exposure means repeated contact with pesticide at low levels over a long period, so the total amount absorbed builds up over time. Even small, frequent exposures can lead to long‑term health effects, either gradually or after a delay, and symptoms may be subtle or intermittent. This contrasts with acute exposure, which involves a large dose in a short time and causes immediate, severe symptoms. A single event exposure is a one‑time incident, which may be acute if the dose is high. Acute poisoning refers to rapid, severe illness after a high dose. So the description that best fits chronic exposure is repeated exposure to low levels over a period of time.
