What is defined as a one-time or short-term contact with pesticide?

Acute exposure refers to a one-time or short-term contact with a pesticide, typically occurring over a short duration and often resulting in immediate effects. This type of exposure is characterized by a rapid onset of symptoms or adverse effects due to a significant amount of the substance being absorbed by the body within a short period.

Understanding acute exposure is crucial for pesticide applicators, as it allows them to recognize the symptoms of pesticide poisoning that can arise quickly and necessitate immediate action. This contrasts with chronic exposure, which involves repeated or continuous contact over an extended period and may lead to long-term health effects. Chronic toxicity and continuous exposure also suggest longer-term interactions with pesticides, which differ significantly from the immediate and often acute effects associated with acute exposure.
