In the context of solving pollution problems, what is/are the advantage/advantages of bioremediation technique?
- It is a technique for cleaning up pollution by enhancing
- Any contaminant with heavy metals such as cadmium
- Genetic engineering can be used to create microorganisms
specifically designed for bioremediation. Select the correct answer using the code given below:
Explanation
The correct answer is 1 and 3 only. Bioremediation leverages natural processes, utilizing microorganisms to degrade pollutants, aligning with option 1, which emphasizes enhancing existing biodegradation mechanisms found in nature. Option 3 is also valid as genetic engineering allows for the development of specialized microorganisms that can more effectively address specific contaminants. However, option 2 is inaccurate since heavy metals like cadmium and lead are not typically biodegradable, and bioremediation is less effective for such contaminants compared to organic pollutants.
