Abstract
In September, 1953, two sections of the British Association (Botany and Forestry) jointly discussed the effects of various components of air pollution. Conclusions reached included the position that the symptoms of ill health in plants that have been subjected to a polluted fog are due not so much to reduction in availability of light as to the presence of toxic substances in the atmosphere. Examples of these symptoms include shedding of flowers and leaves, blackening and death of buds and flowers, scorching of foliage, and complete destruction of more sensitive plants. Sulfur dioxide was identified as one of the more important toxic substances. Practical remedies for the problem were discussed, and the currently-known dose-response relationships (concentrations in excess of 0.5 ppm were known to cause lesions on some plants) were defined. Instances of reduced growth of crop plants and the inhibition of development of lichens and mosses were recounted. The complex relationships between soil condition and air pollution of the growth of plants were discussed.
