What is one potential environmental impact of using pesticides in aquatic systems?

• A. Increase in fish populations
• B. Contamination of water sources
• C. Improved clarity of water
• D. Restoration of native habitats

Answer: (B)

The potential environmental impact of using pesticides in aquatic systems includes the contamination of water sources. When pesticides are applied, they can leach into surrounding water bodies through runoff or direct application, leading to chemical residues that can adversely affect aquatic life, water quality, and ecosystem health. This contamination can not only harm fish and other wildlife but also pose risks to human health if these water sources are used for drinking or recreation. In contrast, the other options do not accurately reflect the typical consequences associated with pesticide use in aquatic environments. While one might hope for increased fish populations or improved water clarity, the reality is that pesticide contamination often leads to harmful disruptions in these ecosystems. Additionally, while restoration of native habitats is a positive goal, the introduction of pesticides generally conflicts with this objective, as it can further degrade the environment rather than support its recovery.
