What kind of damage can runoff from pesticide application potentially cause?

• A. Soil erosion
• B. Water contamination
• C. Pest resistance
• D. Disease spread

Answer: (B)

Runoff from pesticide application poses a significant risk of water contamination. When pesticides are applied to fields or landscapes, they can wash away during rain events or irrigation, leading to these chemicals entering nearby water bodies such as rivers, lakes, or groundwater. This contamination can have dire consequences for aquatic life, drinking water quality, and overall ecosystem health.

The presence of pesticides in water can disrupt the delicate balance of aquatic ecosystems, harming fish and other wildlife, while also potentially posing health risks to humans who consume contaminated water or fish. In contrast, while soil erosion is a concern in agricultural practices, it is not solely a consequence of pesticide runoff, and pest resistance pertains to the effectiveness of pesticides over time rather than direct environmental damage. Similarly, disease spread relates to pathogens rather than the chemical compounds found in pesticides specifically.
