What is a common characteristic of pesticides that are stored improperly?

Pesticides that are stored improperly can indeed degrade and become hazardous. Improper storage conditions, such as exposure to heat, moisture, or direct sunlight, can cause the chemical composition of pesticides to change, leading to the formation of harmful by-products. Additionally, degradation can render these substances harmful not just to their intended targets (like pests) but also to the environment and human health. As pesticides break down, they may release toxic substances that were not originally part of their formulation.

While it is true that improperly stored pesticides might lose effectiveness or potency over time, the main concern lies with the potential hazards they can pose when their chemical integrity is compromised. This aspect emphasizes the importance of proper storage to ensure safety and effectiveness in their application.
