Plants, both native and cultivated, have been recognized as sensitive indicators of industrially polluted air for over 100 years. Foremost among the early recognized sources of injurious gases were coal and oil burning industries such as smelters and large heating plants. Studies by German workers around the turn of the century established that it was the gases rather than the solids in the smoke which were responsible for the observed injury, and that three of the most damaging of these gases were hydrogen fluoride (HF), chlorine (Cl/sub 2/), and sulfur dioxide (SO/sub 2/). Other industrially produced gases of lesser importance, either because higher concentrations were required to produce injury or because injurious concentrations seldom were encountered, included hydrogen chloride (HCl), ammonia (NH/sub 3/), hydrogen sulfide (H/sub 2/S), bromine (Br/sub 2/), iodine (I/sub 2/) and mercury vapor (Hg). 19 references.
