Which term is the study of the adverse effects of chemicals on living organisms?

• A. Acid
• B. Isotopes
• C. Base
• D. Toxicology

Answer: (D)

Toxicology is the study of the adverse effects of chemicals on living organisms. It looks at how a substance interacts with biological systems, how the dose and duration of exposure influence harm, and how different organisms or individuals respond. This knowledge underpins safety standards, risk assessment, and poison-control guidance by linking exposure levels to potential health effects. The other terms describe chemistry or physics concepts—acids and bases relate to pH, while isotopes are variants of elements—not a field focused on toxic effects.
