Which term describes an extreme reaction to a substance in pesticides?

Anaphylactic shock is a medical emergency characterized by a severe and rapid allergic reaction to a substance, which can include certain pesticides. This term specifically relates to an extreme and life-threatening response that occurs within minutes of exposure. The body's immune system reacts aggressively, leading to symptoms such as difficulty breathing, swelling, and a drop in blood pressure, which can be fatal without prompt treatment.

Understanding this term is crucial for those in fields related to pesticide application and safety, as it highlights the importance of recognizing severe allergic reactions to pesticide exposure. Awareness of anaphylactic shock informs the need for precautionary measures, such as reading labels carefully, using protective equipment, and being prepared to respond to emergencies.

Chronic toxicity refers to the long-term effects of exposure to a toxic substance, rather than an immediate extreme reaction. Local effects describe symptoms that occur at the site of contact but do not indicate systemic or whole-body responses. Systemic effects involve the entire body or specific organ systems but do not denote the specific extreme reaction that anaphylactic shock does.
