Is it true that an empty pesticide container still holds approximately one percent of the original amount of pesticide?

It is true that an empty pesticide container can still hold approximately one percent of the original amount of the pesticide. This residual amount can occur due to the nature of the pesticide adhering to the sides of the container even after it has been emptied. Proper cleaning and rinsing are vital to ensure that any leftover pesticide is removed completely, as this helps to mitigate the risks associated with pesticide exposure and contamination.

In addition, regulations often emphasize the importance of rinsing containers before disposal or recycling to minimize environmental impact and ensure safety. Understanding that even an "empty" container can pose a risk underscores the importance of proper handling and disposal methods for pesticide containers.

Other options may suggest that the amount varies or that it’s only true for certain situations, but the generalized stance on residuals applies broadly across most pesticide containers unless specifically designed otherwise.
