Background The use of vegetal organisms as indicators of contamination of the environment is partially replacing traditional monitoring
techniques. Amongst the vegetal organisms available, mosses appear to be good bioindicators and are used for monitoring anthropogenic
and natural fall-out on soils. This study has two objectives: the evaluation of the concentrations of heavy metals in soils
and mosses of the Sicily Region, in Italy and the identification of the origin of fall-out of heavy metals.
Methods Mosses and the surface soil were sampled at 28 sites, only the youngest segments of Hylocomium splendens and Hypnum cupressiforme,
corresponding to the plant tissues produced during the last 3 years, were taken. The elements Cd, Cu, Ni, Pb and Zn were analysed
by ICP-MS and Hg by AAS. Statistical analysis was by PCA and spatial representation by GIS.
Results and Discussion In the mosses sampled in Sicily, the highest concentrations of Cd were found around the cities of Palermo and Messina. The
highest concentrations of Hg were recorded in the northern part of the island between Trapani and Messina, similar to the
distribution of Cu. Different areas with the highest concentrations of Ni were found near the south coast, in the vicinity
of Palermo and around the Volcano Etna. The highest concentrations of Pb were found in the south-west coast near Agrigento,
where important chemical plants and petroleum refineries are located. Except for a few locations, Zn fall-out was found to
be evenly distributed throughout Sicily.
Conclusion The sites where the concentrations of heavy metals cause greatest concern have been revealed by the PCA analysis and portrayed
using GIS. Also of some concern is the diffuse and anthropogenic origin of Hg and Cd. The combined approach of using soil
and mosses, together with pedological interpretation and application of multivariate statistical techniques has provided valuable
insight into the environmental aspects of heavy metal deposition in a region of southern Europe.
Recommendations and Outlook Further insight into the deposition of heavy metals will require more detailed sampling of soils and mosses in both new and
previous study areas. This needs to be complemented by detailed pedological investigations in the study areas. Future research
programmes will address these issues. 相似文献

From February 15th to April 15th 2009, a period characterised by two episodes of Saharan dust outbreaks in Italy, particulate matter (PM) samples were collected at two stations (urban and suburban) in Rome. Some samples were selected and analysed using the SEM-EDS technique to characterise PM, focussing especially on the mineral contribution. Samples were representative both of days affected by Saharan dust episodes and days without this contribution. Cluster analysis allowed the attribution of each of about 67,000 analysed particles to one of the seven main statistical groups based on their composition. Characteristics of the particulate components identified using SEM-EDS analysis were verified by PIXE analysis carried out on filters collected in a suburban area. Ultimately, the contribution of crustal particles was revealed to be consistently high, highlighting the importance of local and regional mineral contributions, as well as those of Saharan origin. Therefore, quantifying all mineral contributions to resuspended particulate could lead to significant reductions of the PM level also on days not influenced by Saharan dust, thus limiting conditions when PM?? daily limit value (DLV) established by European legislation is exceeded. 相似文献
