What characterizes chronic effects of pesticide exposure?

Chronic effects of pesticide exposure are characterized by their development over a long period, often spanning years. This slow progression distinguishes chronic effects from acute effects, which manifest immediately after exposure. Individuals may not notice or attribute symptoms to pesticide exposure until significant time has passed, making awareness and recognition more challenging. This characteristic of chronic effects underscores the importance of long-term monitoring and understanding the cumulative impacts of pesticide exposure on health and the environment.

The other answers imply immediate reactions, reversibility, or mildness, which are not typical of chronic effects. Chronic effects are often more subtle and may occur after repeated or prolonged exposure rather than being immediately felt.
