Why are lichens sensitive to atmospheric pollution by sulphur dioxide?
Lichens are sensitive to sulphur dioxide because their efficient absorption systems result in rapid accumulation of sulphur when exposed to high levels of sulphur dioxide pollution. The algal partner seems to be most affected by the sulphur dioxide; chlorophyll is destroyed and photosynthesis is inhibited.
What does the presence of lichens say about the air quality?
Without the health risks of air pollution, fresh air feels great for our lungs. Lichens love clean air too – in fact, their sensitivity to air pollution means they make great air quality indicators. Like small signposts, these curious organisms can tell us a lot about the air we are breathing.
