The chemical composition of fir needles is altered by the accumulation of fluoride. Our data indicate that fluoride pollution tends to reduce the concentration of Mg and Mn and to increase the concentration of Ca and of F. They also indicate that the fluoride level has no consistent effect on levels of other major nutrient elements, such as N, P and K. Nevertheless, when the content of fluoride in needles reaches 400 ppm no further depletion of Mg and Mn occur. Above 400 ppm fluoride has no significant effect on the levels of the remaining elements. Moreover, a similar depletion of Mg and Mn in relation to fluoride accumulation is observed and a distinct correlation may be found between these two elements. 27 references, 6 figures, 1 table.
