What does the term 'residues' refer to in the context of pesticide use?

The term 'residues' in the context of pesticide use specifically refers to the leftover pesticide that remains on plants, soil, or other surfaces after the application process. This leftover residue can be a concern for both food safety and environmental health, as it may affect what consumers are exposed to when they eat treated crops or engage with treated environments. Recognizing and managing pesticide residues is vital for ensuring compliance with safety regulations and for minimizing potential adverse effects on human health and non-target organisms.

Other options do not accurately describe residues. Unrelated chemical components do not pertain to pesticide use specifically and do not reflect the context of residues. Animal byproducts in agricultural settings refer to substances derived from animals rather than pesticides. Lastly, packaging materials left after application are not related to residues as they pertain to waste rather than leftover substances from the pesticide itself.
