A treatment for lead exposure that involves administering a drug that binds to lead and facilitates its excretion from the body is called:

The correct term for the treatment of lead exposure that involves administering a drug capable of binding to lead and facilitating its excretion from the body is known as chelation. This treatment is crucial in mitigating the harmful effects of lead toxicity, which can affect various bodily systems, particularly the nervous system.

In the process of chelation, a chelating agent—typically a specific type of medication—binds to lead ions in the bloodstream. This binding forms a stable complex that the body can recognize and eliminate through the kidneys. By enhancing the excretion of lead, chelation therapy effectively reduces the overall burden of lead in the body, which is essential for preventing both acute and chronic health complications associated with lead exposure.

Other options offered do not accurately define this medical intervention. Plumbism refers to the condition of lead poisoning itself rather than a treatment method. Plumbum extraction and frumentum deletion are not recognized terms in this context and do not convey any established medical practice related to lead exposure or toxicity. Understanding the designation of chelation is vital for professionals in environmental health, particularly when addressing cases of lead contamination and poisoning.
