In studying the effects of sulfur dioxide upon vegetation it was found that methods of determination of the low concentrations of gas causing minimal injury to plants were unsatisfactory. Any method for this purpose may be subject to errors because the gas is invisible, extreme dilution must be used, changes in temperature cause changes in volume, the gas is adsorbed on surfaces, and oxidation from sulfur dioxide to sulfur trioxide is relatively rapid. The investigations indicate a point of general interest with reference to effects of the gas upon vegetation near industrial plants which emit sulfur dioxide from smokestacks. The relatively rapid oxidation of sulfur dioxide to sulfur trioxide confines the former to a rather small radius, limiting liability to injury to a more reduced area than is sometimes supposed; consequently the damage done to vegetation is likely to be very slight.
