Abstract
A method is presented for determining the intensity of air pollution by evaluating the frequency of lichen species growing on the trunks of trees. The lichens growing on the trunks of isolated trees in the surroundings of factories or other pollutants have been investigated. A ladder enclosing the panels is used to determine the frequency: the calculation is made electronically and permits statistical statements about the quantity of the lichens to be made. The numerical material evaluated consists of reproduceable data obtained by a standardized method that appears to be suitable for routine use. Pollution zones can be recognized by changes in frequency of the various sensitive species.
