Hazard in pesticide use is defined as the product of which factors?

• A. Toxicity and Exposure
• B. Formulation and Application Rate
• C. Duration of exposure and susceptibility
• D. Environmental persistence and solubility

Answer: (A)

Hazard reflects the potential for harm when a pesticide is used, and it depends on two main factors: how toxic the chemical is and how much exposure people or the environment have to it. Inherent toxicity means the chemical’s capacity to cause harm if contact occurs. Exposure covers the amount, duration, and route of contact—how much of the pesticide people or ecosystems actually encounter. If toxicity is high or exposure is high, the hazard increases, and if both are low, hazard is lower. Other factors like formulation or application rate influence exposure levels, while duration of exposure, susceptibility, and environmental fate affect effects and risk, but hazard itself is defined by the combination of toxicity and exposure.
