Environmental pollution by fluorides in Flathead National Forest and Glacier National Park

;
The US Forest Service initiated a study in 1969 to determine the major cause of vegetational injury and damage on forested lands proximal to the Anaconda Aluminum Company, the source of the cause, the area affected, whether insects were accumulating fluorides, and if insect populations were being affected by fluorides in the Flathead National Forest and Glacier National Park. Fluorides emitted from the Anaconda Aluminum Company were determined to be the primary cause of the injury and damage to vegetation in the surrounding area. Data indicated that fluorides were carried by air movement to Glacier National Park. Varying degrees of visible fluoride injury were found on more than 69,120 acres. Elevated fluoride levels were found in vegetation on more than 214,000 acres. Histological reactions to elevated fluorides occur in conifer needle tissue. Fluorides were found to accumulate in insect tissue. Insect population samples indicated that elevated fluoride levels in pine needles leads to a buildup of the pine needle scale. 27 references, 16 figures, 2 tables.
