Chronic exposure means being exposed to small amounts of a substance over a long period of time. This type of exposure can lead to chronic effects that may not be immediately obvious.
Chronic exposure means being exposed to small amounts of a substance over a long period of time. This type of exposure can lead to chronic effects that may not be immediately obvious. For example, long-term exposure to cigarette smoking, low level radiation, and moderate alcohol use can all result in chronic effects. In contrast, acute exposure occurs rapidly after exposure to a large amount of a substance.
