PLANT STUDY; EFFECT OF TEMPERATURE, MOISTURE AND LIGHT ON THE COMPOSITION OF PLANTS GROWN BY USE OF ION EXCHANGE RESINS AS MEDIA,
Abstract
A technique suitable for measurement of atmos pheric contamination of plants was worked out and tested. The growth media used consisted of a mixture of cation and anion resins, the composition of which was adjusted by use of the Donnan Theory so as to provide a solution com position satisfactory for plant growth. Water was supplied by use of a glass wick. The test experiment involved three levels each of light, temperature and water use. The grwoth period was 21 days. Plant foliage was analyzed for F, Cl, S, Cs, Li, Rb, Al and B. The levels of con tamination required for detection by this tech nique vary as follows: Li < Rb < F < Al < B < Cl < S. If adequate analytical techniques were available, Cs could be added to this list perhaps between Li and Rb. If the technique were applied without publicity, some curiosity likely would be aroused among the people as to what was being done. (Author)
