Under What Conditions Would a Pesticide Be Most Polluting

Question

Under what conditions would a pesticide be most polluting?
A) If it is unselective and persistent
B) If it is selective and has a short half life
C) If it does not biomagnify in the food chain
D) If it biomagnifies in the food chain

Accepted Answer

A pesticide would be most polluting if it is unselective and persistent (A), meaning it kills a wide range of organisms and remains in the environment for a long time, and if it biomagnifies in the food chain (D), meaning its concentration increases as it moves up the food chain, potentially harming predators at the top.
