Section 2: The Risks and Challenges of Pesticide Residues
2.1 Understanding Pesticide Residues
Pesticide residues are trace amounts of these chemicals that can linger on agricultural products after application. These residues can be found on the surface of crops, within the plant tissues, and in the surrounding environment.
Pesticide residues, in their brief presence, can manifest in multiple forms and locations. They can be found on the surface of crops, often clinging to the outer layers of leaves, fruits, or grains. These surface residues are the most visible and accessible, and their management is crucial in minimizing human exposure by consuming untreated produce.
They can infiltrate the very tissues of the plants themselves, permeating roots, stems, leaves, and even fruits or seeds. Furthermore, pesticide residues can extend their reach into the surrounding environment. They can contaminate soil, persist in water bodies, and even enter the atmosphere, creating a complex web of potential exposure pathways.
