What is the definition of chronic toxicity?

• A. Immediate harmful effects from a high dose
• B. Delayed damaging effects from repeated low-level exposure
• C. Acute toxicity from a single exposure
• D. Effects that disappear after treatment

Answer: (B)

Chronic toxicity refers to the harmful effects that occur as a result of repeated low-level exposure to a toxic substance over an extended period of time. Unlike acute toxicity, which is characterized by immediate adverse effects resulting from a high dose or a single exposure, chronic toxicity develops gradually and may not be immediately apparent. Individuals exposed to low doses consistently over time can accumulate the harmful effects, leading to long-term health consequences. This understanding of chronic toxicity is crucial in fields such as environmental health, toxicology, and occupational safety, as it emphasizes the importance of monitoring and managing prolonged exposure to potentially harmful agents. Recognizing the subtle onset of symptoms associated with chronic toxicity helps in implementing preventive measures and ensuring the safety of individuals and communities who might be at risk.
