The correct Answer is:
To determine which pesticide is more persistent in the soil, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: We need to identify which pesticide is the most persistent in the soil among the given options: DDT, BHC, Deldrin, and Vagon. 2. **Define Persistence**: Persistence in this context refers to how long a pesticide remains active and unchanged in the environment, particularly in the soil. More persistent pesticides can have prolonged effects on the ecosystem. 3. **Evaluate the Options**: - **DDT (Dichloro-Diphenyl-Trichloroethane)**: Known for its effectiveness in killing pests but has been banned in many countries due to its environmental impact. - **BHC (Benzene Hexachloride)**: Also used as a pesticide, but less persistent than some others. - **Deldrin**: An organochlorine pesticide known for its high toxicity and persistence in the environment. - **Vagon**: Less commonly referenced, and its persistence is not as well-known compared to the others. 4. **Identify the Most Persistent Pesticide**: Among the options, Deldrin is recognized as being significantly more persistent in the soil compared to DDT and BHC. It is an organochlorine compound and is known to remain in the environment for extended periods. 5. **Conclusion**: Based on the information gathered, the pesticide that is more persistent in the soil is **Deldrin**. ### Final Answer: The pesticide more persistent in the soil is **Deldrin**. ---
