The duration of exposure refers to the length of time an individual is exposed to a toxic substance. It can be categorized into three main types:
Acute Exposure: Short-term exposure, typically lasting for less than 24 hours. Subacute Exposure: Exposure lasting from one day to one month. Chronic Exposure: Long-term exposure, lasting for months or even years.
The duration can significantly impact the toxicity and biological effects of a substance. For example, a single acute exposure to a high dose of a toxin may cause immediate health effects, whereas chronic exposure to lower doses may lead to cumulative damage over time.
