Is chronic toxicity caused by a single exposure to a pesticide?

Chronic toxicity refers to the harmful effects that may result from prolonged exposure to a substance, typically over a long period of time. This type of toxicity is not typically associated with a single exposure to a pesticide but rather with repeated or continuous exposure that builds up in the body over time.

In the context of pesticides, chronic effects may include damage to organs, endocrine disruption, or cancer, which often require sustained exposure to manifest. It's important to distinguish these long-term effects from acute toxicity, which is the result of a single, high-dose exposure leading to immediate adverse effects.

Therefore, the assertion that chronic toxicity can be caused by just a single exposure to a pesticide is incorrect, making "False" the appropriate answer. This distinction underscores the importance of understanding both the short-term and long-term risks associated with pesticide exposure in environmental health and safety considerations.
