Resumen:
Multi-elemental profiles in bark of
green ash trees collected in three representative
areas of Buenos Aires, Argentina and Montevideo,
Uruguay, were assessed as potential air
pollution indicators. Ten elements: Al, Ba, Cr,
Cu, Fe, Mg, Mn, Ni, Pb, and Zn, were measured
using inductively coupled plasma optical emissions
spectrometry from 70 samples collected in
different environments: central, residential and
rural (reference site), in order to compare spatial
patterns of metal concentration. The samples used
as a control were collected from a nature reserve
situated far away from any significant influences,
not even a nearby road. The reference site (RF)
exhibited the lowest concentrations of Al, Cr, Fe,
Ni, Pb, and Zn. However, Ba and Mn showed
similar concentrations in all measured sites. Magnesium
is the only element that had a greater
concentration in RF than at the other sites. Copper
did not show any clear pattern. The Centre
of Montevideo (MVD) showed higher concentrations
of Al, Ba, Cr, Fe, Pb and Zn than the Centre
of Buenos Aires (BA). In the A sectors, Montevideo
(SAMVD) showed higher concentrations of
Al, Cu, Mg, Ni, and Zn and lower concentrations
of Ba, Cr, Fe, Mn, and Pb than Buenos Aires
(SABA). In the B sectors, Montevideo (SBMVD)
showed higher concentrations of Al, Ba, Cu, Fe,
Pb, and Zn and lower concentrations of Cr and
Mg than Buenos Aires (SBBA), but similar concentrations
of Mn and Ni. The use of bark for
biomonitoring metals allowed us to detect concentration
differences related to the urban fabric and
the different kinds of vehicles and their fuels. In
the cities, the differences in metal concentrations
detected in bark were more striking between the
sectors than between centers, despite CBA being
much larger than CMVD in population, extension
and vehicular traffic.
