This study was concerned with the differentiation and measurement of small, intermediate, and large ion densities in a sealed room. It was found that the background density of large negative ions exceeded that of any other class. Under conditions of tobacco smoke pollution, large ions of both positive and negative charge were the major components of the air ion population. This was accompanied by a persistent attrition of high mobility ions both during and after smoking.
