Which term describes adverse health effects resulting from frequent exposure to small amounts over time?

• A. Acute toxicity
• B. Hypersensitivity
• C. Chronic toxicity
• D. Carcinogenicity

Answer: (C)

Long-term, low-dose exposure that gradually harms health describes chronic toxicity. This term fits when adverse effects develop after repeated contact with small amounts over an extended period, often due to the buildup of a substance in the body or ongoing damage from ongoing exposure. In contrast, acute toxicity refers to harmful effects from a single large dose or exposure over a short time. Hypersensitivity involves an immune‑mediated reaction, such as an allergy, which can occur even at low doses but isn’t defined by cumulative exposure. Carcinogenicity is about the potential to cause cancer, which is a related risk but not the defining idea of accumulating harm from repeated small exposures. An example of chronic toxicity would be liver damage from years of solvent exposure or nerve damage from ongoing pesticide exposure.
