Accurate fluoride determinations throughout polluted fir needles

Journal Article · · Fluoride; (United States)
OSTI ID:6443619

By means of a new analytical method in plant biology, microanalysis by proton nuclear reaction, fluoride assays were made of the surface tissue of polluted needles of fir trees. Two distinct peaks of fluoride accumulation were established: the first in the extreme tip of the needle's necrotic area, the second in the narrow strip which separates the healthy from the injured tissue. The magnitude of these two accumulations and the distribution of fluoride throughout the needle is related to the age of the needle. The amounts of fluoride differ depending upon which side of the needle is measured; the upper surface takes up more fluoride than the lower one.
