Which statement correctly distinguishes toxicity from hazard?

• A. Toxicity describes inherent harmful properties
• B. Toxicity is the potential to cause adverse effects
• C. Hazard and toxicity are identical
• D. Hazards evaluate toxicity

Answer: (A)

Toxicity is about the substance’s inherent ability to cause harm—the intrinsic harmful property of the chemical or agent. Hazard, by contrast, is about the potential for that harm to occur under real-world conditions when exposure happens. So the statement that toxicity describes inherent harmful properties correctly captures the distinction. Exposure context matters: a chemical can be highly toxic yet pose little hazard if there is no meaningful exposure, while a less toxic substance can still pose a hazard if exposure is unavoidable. The other options mix up intrinsic properties with exposure potential or imply that hazard and toxicity are the same, or that hazards merely evaluate toxicity, which isn’t how risk is considered.
