What characterizes acute effects of pesticide exposure?

Acute effects of pesticide exposure are characterized by immediate symptoms or reactions that occur shortly after an individual comes into contact with the pesticide. This can include a range of symptoms that manifest quickly, such as headaches, nausea, skin irritation, or other physical responses that become apparent soon after exposure to the chemical.

This term specifically differentiates acute effects from chronic effects, which would refer to impacts that develop over a longer period of time or stem from repeated exposures. The definitions of the other choices highlight the duration or gradual development of effects, contradicting the definition of acute, which is rooted in immediacy. Therefore, recognizing acute effects is crucial for prompt diagnosis and treatment following pesticide exposure, emphasizing the need for rapid response in such situations.
