Pesticide runoff can contaminate waterways, which poses significant risks to aquatic environments. When pesticides are applied to agricultural fields or other areas, rainwater or irrigation can wash these chemicals into nearby rivers, lakes, and streams. Once in aquatic ecosystems, pesticides can have detrimental effects on water quality, harming wildlife and disrupting the balance of these ecosystems.

The introduction of harmful chemicals can lead to a decrease in biodiversity, affecting both plant and animal species. Non-target organisms, including fish, amphibians, and aquatic invertebrates, can be particularly vulnerable to these contaminants. The consequences may range from acute toxicity, which can cause death in some cases, to chronic effects that impair reproduction and development among aquatic species.

Understanding the impact of pesticide runoff is essential for managing agricultural practices and protecting water resources. This ensures sustainable practices that minimize adverse effects on ecosystems while still allowing for necessary pest control measures.
