Which combination of properties makes a pesticide the greatest long-term hazard to a food chain?
ARapid photolysis and high solubility in fats
BLow persistence and low volatility
CRapid hydrolysis and high solubility in water
DHigh persistence in soil and high solubility in fats
Answer: D
A long-lived compound remains available for uptake, and fat solubility lets it be stored in tissue and passed up the food chain. Rapid breakdown or high water solubility prevents accumulation.
