What are the risks associated with storing pesticides in improper containers?

Storing pesticides in improper containers presents several significant risks, primarily due to the potential for chemical reactions, leaks, and contamination. When pesticides are stored in containers that are not designed for that specific chemical, they may react negatively with the materials of the container. This can lead to the breakdown of the pesticide itself or the container, resulting in leaks that not only waste chemicals but also pose environmental and health hazards.

Contamination is another critical risk; pesticides can mix with other substances if they leak or if they are stored in containers that previously held other chemicals. This can create harmful mixtures that are unpredictable and dangerous, both for applicators and the environment.

In contrast, the other choices indicate scenarios that do not occur with improper storage. Increased effectiveness and stability, longer shelf life, and reduced potency are not outcomes associated with poor storage practices; rather, they can lead to diminished effectiveness and even hazardous situations. Proper storage is essential for maintaining the integrity, safety, and effectiveness of the pesticides.
