The vulnerability assessment of these soils, taking into
account the values of the soil buffering capacity index,
within the considered area, shows that soils with high
vulnerability to the polluting impact represent 68%, while
soils with moderate vulnerability represent 22% and soils
with low vulnerability represent only 10% (Fig. 1). The
ranking of soils according to the natural vulnerability to the
impact of acid rains accompanied by heavy metals is
presented in Table 2. The conclusion is that the nature of
soils is largely prone to some increased effects of soil
chemical and physical degradation.
