What term describes the degree to which a substance is biologically harmful?

• A. Toxicity
• B. Acute Toxicity
• C. Chronic Toxicity
• D. Lethal

Answer: (A)

The degree to which a substance is biologically harmful is described by toxicity. This term captures the overall potential of a chemical to cause harm to living organisms, considering factors like dose, exposure duration, and the way exposure occurs. Acute toxicity refers to harmful effects that happen soon after a short-term exposure, while chronic toxicity concerns damage that results from long-term exposure. Lethal describes causing death, which is a severe outcome, but it doesn’t define the general level of harm a substance can cause—the broader concept of toxicity does.
