Pesticide bioaccumulation potential describes which concept?

• A. The pesticide's ability to degrade quickly.
• B. The ability of an organism to store and accumulate a pesticide, enabling transfer up the food chain.
• C. The pesticide's volatility in air.
• D. The pesticide's solubility in water.

Answer: (B)

Bioaccumulation potential describes how a pesticide can build up inside an organism over time. When a chemical remains in the body or is stored in fatty tissues faster than it’s broken down or excreted, its concentration can rise. As predators eat contaminated prey, these concentrations can increase further up the food chain, a process known as biomagnification. That’s why pesticides with high bioaccumulation potential pose greater risks to wildlife and humans through long-term, dietary exposure.

Degradation rate is about how quickly a chemical breaks down, which affects persistence but not the buildup inside organisms. Volatility describes how easily a substance becomes a vapor and moves through air. Water solubility influences movement in water, but it doesn’t by itself describe accumulation in organisms.
