Which of the following is the use of lichens in case of pollution?
Correct answer: D. They act as bioindicators of pollutions
- A. They promote pollution
- B. Lichens are not related to pollution
- C. They treat the polluted water
- D. They act as bioindicators of pollutions
Explanation
Lichen biomonitoring has been widely used in environmental research and air quality assessment. It provides valuable insights into the impact of pollutants on ecosystems and human health. Lichens are particularly useful in areas where air quality monitoring equipment may be limited, and they offer a cost-effective and non-invasive way to assess pollution levels over time. Lichens are very sensitive to SO2 pollution. They are completely destroyed at places where there is SO2 pollution in the atmosphere. Therefore, they act as very good indicators of SO2 pollution.
