Which type of exposure involves multiple contact events over time?

Chronic exposure refers to prolonged or repeated exposure to a substance over an extended period, often involving multiple contact events. This type of exposure typically occurs in scenarios where an individual encounters low doses of a pesticide or chemical substance over time, such as through diet, air, or water.

In the context of pesticide application, chronic exposure can happen to individuals living near agricultural areas where pesticides are regularly used, leading to the accumulation of chemicals in the body. The health effects of chronic exposure can develop slowly and may manifest over years, making them more challenging to identify compared to acute exposure, which is defined by a single, short-term exposure event.

Understanding chronic exposure is crucial for assessing long-term health risks and for implementing safety measures in agricultural practices, ensuring that both applicators and the surrounding community are protected from adverse effects associated with prolonged exposure to pesticides.
