Monitoring fluoride pollution in Flathead National Forest and Glacier National Park
Carlson CE and USDA Forest Service Norhtern Region. 1974. Monitoring fluoride pollution in Flathead National Forest and Glacier National Park. Report 74-5. US Forest Service. Northern Region Insect and Disease Branch. Missoula, MT
During August 1972, 15 vegetation plots monitored for foliar fluoride concentrations in 1971 were resampled near the Anaconda aluminum plant at Columbia Falls, Montana. Statistical analysis of the data showed that essentially the same amount of fluoride was taken in by conifers, shrubs, and grasses in 1972 as in 1971. It is concluded that the area over which plants accumulated fluoride and resultant damage occurred remained unchanged from 1971 at 179,000 acres and 15,000 acres, respectively. Vegetation in Glacier National Park continued to show some fluoride injury and to accumulate abnormally high amounts of fluoride.
