Which of the following is a result of improper pesticide disposal?

Improper pesticide disposal can lead to soil and water contamination, which is a significant environmental concern. When pesticides are not disposed of correctly—such as being poured down drains, thrown in the trash, or spilled on the ground—they can leach into the soil or run off into nearby water bodies. This contamination can have detrimental effects on ecosystems, harming aquatic life and disrupting the balance of soil microorganisms essential for healthy plant growth. Furthermore, contaminated water sources can pose health risks to humans and animals that rely on that water for consumption.

On the other hand, improved soil fertility, decreased pest resistance, and enhanced pest attraction are not results of improper pesticide disposal. Improved soil fertility is typically associated with responsible agricultural practices and the addition of organic matter or amendments rather than the harmful effects of pesticides. Similarly, decreased pest resistance is usually achieved through proper pest management strategies, including rotating pesticides and employing integrated pest management rather than through improper disposal methods. Lastly, enhanced pest attraction would generally not be a consequence of pesticide disposal but rather the result of factors such as habitat and food availability.
