Volatility is a measure of volatility's effect on a pesticide's behavior:

• A. Time a pesticide remains active in the environment
• B. Tendency for a pesticide to turn into a vapor or gas
• C. Ability to bioaccumulate in the food chain
• D. Persistence in soil

Answer: (B)

Volatility is about how readily a pesticide becomes a gas and moves through the air. It relates to vapor pressure and temperature—higher volatility means the chemical can evaporate more easily, leading to vapor drift and potential inhalation exposure, as well as loss from the treated site. This is distinct from how long a pesticide remains active (persistence), how it bioaccumulates in the food chain, or how long it stays and persists in the soil. Those factors describe duration of activity, accumulation potential, and soil residence, not the tendency to volatilize. So the correct idea is the tendency of a pesticide to turn into a vapor or gas.
