Abstract:

While they may not seem significant, lichen play a critical role in sustaining the health of the environment. Lichens may look like small plants, but they’re actually composites of a fungus and an algae. Lichens are sensitive bioindicators of air quality, as they absorb water, minerals, and pollutants like nitrogen and fluoride from the air through rain, dust, and gases. The algae within lichens perform photosynthesis, while the fungal partner absorbs essential nutrients and pollutants. When exposed to air pollution, sensitive lichen species can develop structural changes, such as reduced photosynthesis, bleaching, and even death of the algae or discoloration of the fungal component. Over time, these sensitive species are often replaced by more pollution-tolerant species, providing a clear signal of declining air quality. Lichens are particularly vulnerable to pollutants like sulfur, nitrogen, heavy metals, and ozone, with nitrogen and fluoride being two of the main contributors to t
