Fluorine levels in 1961 crops of the Dalles area
The fluorine contents of seven crops grown in The Dalles area during 1961 are reported. These data are compared to similar data obtained previously. Leaf samples collected from crops in The Dalles area in July 1961, ranged from 12 to 217 ppM fluorine and averaged 65 ppM, while those taken in September ranged from 16 to 204 ppM and averaged 68 ppM fluorine. Similar samples from the Corvallis area all contained 13 ppM fluorine or less. Leaf scorch of apricot trees and soft suture on peach fruits were observed in 1961 in The Dalles area orchards. These conditions were observed in 1959 and 1960, but not prior to the operation of an aluminum factory located in this area. 6 references, 1 figure, 14 tables.
