Correct Answer: Soil & Water
Solution : The correct option is Soil & Water.
DDT spraying can cause soil and water contamination due to its long-lasting nature and ability to leak into groundwater. Rainwater and runoff can transport DDT residues from farms to surrounding aquatic bodies, contaminating them. Furthermore, the potential of DDT to bioaccumulate in species can lead to dangerous amounts in the food chain, affecting both aquatic and terrestrial ecosystems. This pollution endangers the environment, affects aquatic life, and can impact human health through the eating of tainted crops and water. As a result, several governments have limited DDT usage and promoted sustainable alternatives to reduce environmental and health risks.
