“…However, Zn values (mean = 39.5 ppm) and Pb (mean = 6.59 ppm) in F. pennsylvanica are below the range found by these authors (Zn range: 59-780 ppm; Pb range: 100-1000 ppm). Nevertheless, they are similar to the values observed by Perelman et al (2006) in bark of F. pennsylvanica in downtown Buenos Aires (mean Zn = 29.17 ppm; mean Pb = 6.38 ppm), suggesting that the emission level for these elements in these two cities in Argentina could be similar.…”

In order to evaluate the use of Fraxinus pennsylvanica as a biomonitor of trace elements and to investigate their relationship with the incidence of some respiratory diseases in children, bark samples of F. pennsylvanica were collected at ten sampling sites near healthcare centres in Córdoba city, Argentina, and analysed by Total Reflection X-ray Fluorescence with synchrotron radiation. Factor analysis was used to identify element emission sources. The first factor was associated with industrial activities, the second might represent soil sources and the third factor was related to vehicular traffic emissions. Pearson's correlation analysis between these factors and the incidence of respiratory diseases showed that factor 1 correlated with allergic rush, factor 2 with allergic rhinitis and factor 3 with respiratory infections. The results suggest that bark samples of F. pennsylvanica can be use as an efficient biomonitor to assess the human exposure to trace elements.

“…Os elementos Ba, Co, Cr, Cu, Fe, S e Zn provavelmente são provenientes de atividades antrópicas, pois apresentaram concentrações bem mais elevadas nos parques do que na região rural (controle), bem como mostraram altas concentrações na periferia dos parques, indicando uma possível contribuição veicular. Estes elementos são amplamente citados na literatura como "elementos relacionados ao tráfego" (Bohm et al, 1998;El-Hazan et al, 2002;Monaci et al, 2000;Fuga et al, 2008;Schelle et al, 2002;Perelman et al, 2006;Silva, 2007) . et al, 1998;El-Hazan et al, 2002;Kuang et al, 2007).…”

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.
