What is the Importance of Exposure Duration and Frequency?
Exposure scenarios also consider the duration and frequency of exposure. Acute exposure refers to a single or short-term exposure, typically less than 24 hours, while chronic exposure involves repeated exposures over a longer period, such as months or years. The pattern of exposure can lead to different toxicological outcomes. For example, chronic exposure to low doses of a substance could lead to cumulative effects, while acute exposure to a high dose might cause immediate toxic effects.
