An empty pesticide container still holds approximately what percentage of the original amount of pesticide?

An empty pesticide container typically retains about 1% of the original amount of pesticide. This residual amount can occur due to the viscosity of the liquid and the design of the container, which may not allow all of the pesticide to be completely poured out. Even after it appears empty, the container can have enough pesticide left that it should be handled and disposed of properly to prevent environmental contamination or unintended exposure.

Understanding this concept is crucial for safe pesticide handling and disposal, as it emphasizes the importance of thoroughly cleaning and managing pesticide containers, even when they seem empty. Proper disposal methods typically require rinsing and recycling or disposing of the containers according to local regulations, highlighting the potential risks associated with residues that can remain in containers.
