Mitchell, J P

In recent years the effects of smelter smoke on vegetation has become a serious problem as a result of the development of very large smelting establishments. Smelter smoke is peculiarly obnoxious because its common constituents, lead and arsenic, are poisonous substances. In addition, sulfur trioxide and sulfur dioxide are present in large amounts where sulfides ores are smelted. The constituent of smelter smoke most injurious is sulfur dioxide. The effect of sulfur dioxide on vegetation is that of a poison and is quite distant. It is absorbed by plant tissue, combines chemically with some constituent of the plant, remains fixed in the tissue, and, when present in sufficient amounts, results in a complete disturbance of the physiological processes normally taking place in the plant cells.
