What can be a consequence of improper pesticide use in aquatic environments?

Improper pesticide use in aquatic environments can indeed lead to negative effects on public health. When pesticides are applied incorrectly, they can contaminate water sources, leading to exposure for humans and animals alike. This can result in a range of health issues, from acute poisoning symptoms to long-term chronic effects, depending on the nature of the chemicals used and the levels of exposure. Contaminated water can also affect food supplies and contribute to the bioaccumulation of toxic substances in the food chain, further impacting public health.

While other choices imply beneficial outcomes such as increased biodiversity, positive recreational fishing, or a reduction in invasive species, these are not typically associated with improper pesticide use. In fact, such misuse often disrupts ecosystems, harming both aquatic life and the quality of recreational activities.
