Which term represents the potential for injury from the use of pesticide, composed of toxicity and exposure likelihood?

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

Answer: (A)

Hazard is the potential for injury from a pesticide, arising from its toxicity and the likelihood of exposure. It reflects how harmful the chemical could be if someone comes into contact with it and how probable that contact is during use. Toxicity tells you how damaging the substance can be, but without considering whether people are exposed, you don’t yet know the potential for harm. Exposure likelihood adds that context—how likely it is that someone will actually be exposed. Put together, these two factors describe the inherent danger or hazard of the pesticide. Risk, by contrast, would involve translating that hazard into the probability of real harm under actual use conditions, which requires more specifics about exposure.
