What seals the pesticide container to prevent leaking during disposal?

Encapsulation is the process that seals the pesticide container to prevent leaking during disposal. This method involves enclosing or covering a substance with a material that prevents the release of harmful chemicals into the environment. In the context of pesticide disposal, encapsulation ensures that any potential leaks or spills are contained, thus protecting soil and water sources from contamination. Effective encapsulation can involve using specially designed containers or materials that maintain structural integrity, even under pressure or during transportation.

The other options do not relate to the sealing of pesticide containers. Hydration typically involves the addition of water to a substance and does not pertain to leak prevention. Incineration is a method for destroying hazardous materials through combustion, while freezing pertains to the storage of substances at low temperatures, neither of which provides a solution for sealing containers during disposal. Understanding the role of encapsulation in safe pesticide handling and disposal is crucial for pest control applicators in minimizing environmental risks.
