Speak to Me, Lichen
In this Catalyst article, students at La Sainte Union Catholic School in North London investigate the link between lichen species and air pollution around their school.
Lichens are indicators of changes in air quality; tolerant species replace those which are sensitive to a given pollutant. This effect is observed across urban and rural Britain, especially in regions where oxidised and reduced forms of nitrogen are present. Nitrogen dioxide is the dominant air pollutant in urban areas, due to pollution from road traffic. Therefore, measuring levels of nitrogen dioxide can indicate the quality of our town air.
