Toxicity multiplied by time equals which concept?

• A. Hazard
• B. Dose
• C. Risk
• D. Exposure

Answer: (C)

Risk is the idea being tested. It combines how harmful the substance could be (toxicity) with how long you’re exposed to it (time). If a chemical is highly toxic, or you’re exposed for a longer period, the overall risk increases. In risk assessment, hazard is the inherent potential to cause harm, exposure is the contact with the substance over time, and dose is the amount absorbed. Risk brings hazard and exposure together, so multiplying toxicity by exposure duration gives a straightforward way to think about overall risk. For example, a very toxic substance with a brief exposure can have similar risk to a less toxic substance with a longer exposure.
