What are two ways for pesticides to move downwind to non-target areas?

  1. By groundwater leaching and surface runoff

  2. By rainfall and irrigation

  3. By reverse osmosis and condensation

  4. By vapor drift and particle drift

The correct answer is: By groundwater leaching and surface runoff

Explanation Pesticides can be transported through the environment in various ways, but the two methods mentioned in option A, groundwater leaching and surface runoff, are the most likely ways for them to move downwind to non-target areas. Groundwater leaching occurs when pesticides seep through the soil and enter underground water sources, which can then carry the pesticides to other areas. Surface runoff, on the other hand, is when rainwater or irrigation water flows over the surface of the ground, picking up pesticides and carrying them to other locations. Options B and C do not involve wind as a factor and therefore are unlikely to contribute to downwind transportation of pesticides. Option D mentions methods of drift, but not specifically downwind drift, making it less relevant to the question. Overall, option A provides the most accurate and relevant explanation for the transportation of pesticides downwind to non-target areas.
