    The Effects Of Low Level Sulfur Dioxide Emissions On The Mineral Content Of Pinus Ponderosa dougl.
    Type
    thesis
    Abstract
    A study was made to determine if there was a cause and effect relationship between the S02 emissions from the ASARCO smelter at East Helena, Montana and the mineral nutrient content of the native species ponderosa pine. While the study failed to prove conclusively that such a relationship exists it established the fact that the Prickley Pear Valley serves as a corridor for smelter stack emissions. Also discussed is the meaning of the unusual pattern of high Potassium and Zinc concentrations.
