Abstract
Thulium is a rare earth element and as such is known to "be a minor product of nuclear processes. As these processes become more and more commonplace, their products will contaminate the "biosphere to an increasing degree. The factors which effect the uptake of thulium "byplants are the focus. The factors which have "been chosen to study are soil pH and the presence of aluminum. Three different types of plants were studied, each of a different aluminum-toxicity: turnip (resistant), pea (moderately resistant), and red clover (sensitive). Each of these plants was grown at three pH values and with and without aluminum in the soil solution. It was found that the uptake of thulium was inversely proportional to the pH of the growth medium in a linear fashion. The presence of aluminum in the uptake medium did have an effect on the mass of thulium taken up and also on its translocation within the plant. No correlation was found "between aluminum-toxicity and thulium uptake.
