... Laurence Boyce Thompson Institute Ithaca, NY 14853 ABSTRACT In most geographical regions, indigenous or cultivated species of plants are present for use as indicators of pollution from ozone, sulfur dioxide, hydrogen fluoride, hydrochloric acid, chlorine, and other phytotoxicants. Where they do not occur, portable "gardens" or lichen "boards" can be distributed in appropriate areas, or gardens can be planted in situ Careful selection of indicator species can not only identify the pollutant or pollutant mixture, but can provide approximate estimates of geographic distribution, source strength, pollutant dose, and can aid in locating particular sources.

... capable of absorbing a pollutant in a predictable manner if it is to be used as a measure of accumulation (14, 15, 17~. Selection of Plant Materials Lists of plant species exhibiting varying degrees of sensitivity to air pollution have been catalogued (3, 4, 5, 7, 14, 15, 24, 25, 26, 29, 34, 49, 50, 51, 54, 55~.
