What is the difference between acute and chronic effects of pesticide exposure?

The distinction between acute and chronic effects of pesticide exposure is primarily based on the timing and duration of the effects experienced. Acute effects are those that occur almost immediately following a significant exposure to a pesticide, often manifesting within hours or days. These effects can include symptoms such as headaches, nausea, skin irritation, or more severe reactions like respiratory distress, depending on the nature of the pesticide and the level of exposure.

In contrast, chronic effects develop more gradually, often as a result of long-term exposure, even if that exposure is at low levels over a prolonged period. These chronic effects may not be apparent until much later, potentially leading to serious health issues such as cancers, reproductive problems, or neurological disorders.

This understanding is crucial for pesticide applicators as it informs their approach to safety, handling, and the necessary precautions to protect themselves and others from both immediate and long-term health risks associated with pesticide use.
