Aggregate Pesticide Exposure means?

• A. All possible sources of exposure to the same pesticide
• B. Only exposure from water
• C. Only exposure from air
• D. Exposure from a single source

Answer: (A)

Aggregate exposure refers to the total amount of exposure to the same pesticide coming from all sources and through all exposure pathways, summed over a period of time. That means if you can encounter the pesticide in drinking water, in the air near treated areas, on contaminated food, in dust or soil, and from occupational or household products, all of those contributions are combined to form the overall risk. This concept matters because even if each individual source seems small, their combined effect can push total exposure above safe levels. So the best description is exposure from all possible sources of the same pesticide, not just water, not just air, and not just a single source.
