Chronic exposure is typically characterized by exposure over what duration?

Explanation:
Chronic exposure is exposure that occurs repeatedly or continuously for a long period, allowing effects to develop over time. This typically means months to years, reflecting the idea that the body may accumulate dose and gradually show toxic effects with prolonged contact, such as increased cancer risk or long-term organ damage. Short-term exposures—lasting seconds, minutes, or hours—tend to cause acute toxicity that appears quickly and is linked to a rapid onset of effects, not the extended timeframe implied by chronic exposure.
