The capacity of a pesticide to cause acute or chronic injury is referred to as its what?

• A. Toxicity
• B. Volatility
• C. Solubility
• D. Persistence

Answer: (A)

Toxicity describes the capacity of a pesticide to cause acute or chronic injury. It’s the inherent potential of the chemical to cause harm when an organism is exposed, covering both immediate effects (acute) and long-term effects (chronic). The actual harm seen depends on exposure, dose, and route, but toxicity is the property that defines how harmful the substance could be.

The other terms describe how the chemical behaves rather than its harm potential: volatility is how easily the pesticide becomes a gas and can be inhaled; solubility is how well it dissolves in water or fats, influencing absorption and spread; persistence is how long it remains active in the environment. While these factors affect risk, they don’t define the inherent capacity to cause injury, which is what toxicity measures.
