Industrial air pollutants, such as organochlorines and heavy metals, are carried to the arctic on air currents from populated areas. Lichens are a dominant life form on the tundra, and they are particularly vulnerable to air pollution because they lack roots and get the majority of their resources from the air. Because of this, lichens have historically been used as air pollution indicators.
