Looking into the analysis of calculations and taking into account the indicators
according to the landscape environment pollution risk assessment scale, we define the
soil contamination intensity category.
We can conclude that the content of zinc and chromium is in excessive amounts,
since they have four categories of pollution intensity.
Consequently, if evaluate the zinc contents, taking into account its minimum and
maximum values (Zn (min) = 8.86, Zn (max) = 52.32), we can note that categories
correspond to four zones of the intensity of pollution, that is: 8.86-15 acceptable; 16-
30 moderately dangerous; 31-50 dangerous; 50-52,32 and very dangerous. Figure 2
shows the migration of Zn in the near areas of the airport.

Similarly, with chromium: Cr (min) = 5.6, Cr (max) = 44:5,
6-15 acceptable;
16-30 moderately dangerous;
31-44 is dangerous.
