Pesticides are widely used to protect crops from pests, with more than a thousand different substances applied worldwide. Each pesticide has unique properties and toxicological effects, and its risk depends on factors such as function, dosage, and route of exposure. For instance, insecticides are generally more toxic to humans than herbicides, while the same chemical can produce very different outcomes depending on how and in what quantity exposure occurs. Reliable analysis is therefore essential to ensure food safety and compliance with international standards.
