“…Several natural archives may provide unaltered records of environmental and climatic information at different time scales dating back up to several hundred thousand years: marine sediments (Bostick et al 2005;Moy et al 2011), stalagmite conformations (Polyak and Asmerom 2001), tree rings (Bernini et al 2016) and deep ice cores (Petit et al 1999;Community Members EPICA 2004;Maggi 1997) to name a few. For instance, the analysis of tree rings is a powerful historical ecology tool due to the inter-and intra-annual responses of the radial growth to local climatic variations.…”

“…In particular, the study of correlation and response functions among tree rings with monthly/weekly climatic factors have been successfully assessed during the past years. Moreover, dendrochemical analyses have shown the possibility of detecting the accumulation of contaminants and pollutants in wood samples during the time (Bernini et al 2016;Filippo et al 2007).…”

XLab Frascati is a facility open to external users for different X-ray analyses, ranging from structural studies through X-ray diffraction to elemental mapping by means of µX-ray Fluorescence, colour tomography and X-ray imaging studies. This is possible thanks to our experimental layouts XENA (X-ray Experimental station for Non-destructive Analysis) and RXR (Rainbow X-Ray) along with our facility for the production of polycapillary optics. The know-how on these optics enable us improving the performances of our setups by adopting the best fitting X-ray optics according to the experimental requirements. To make an example, the main advantage of RXR is that the detection system includes two spectrometers working in high (arranged in the polycapillary confocal geometry) and low X-ray energies,, respectively, permitting both the 2D µXRF scan and 3D µXRF elemental mapping (colour tomography) due to the confocal geometry with a 3-axis fine motion system. The article showcases the results obtained in key case studies where we performed: (i) 2D/3D µXRF to analyse chemical composition of tree rings with respect the influence of the environmental context, to study a "fresco" fragment and assess the presence of damages, to make a 3D reconstruction of a screw encapsulated in glue through the its elemental composition as well as (ii) X-ray imaging and (iii) µCT/dynamic CT to characterize LiF detectors, to study the structure of a flower bud and to evaluate the profile distribution of a diesel spray from the nozzle.

Thirty-two trace elements were examined in the tree rings of downy oak to evaluate the pollution levels close to a cement plant isolated in a rural context and an industrial area where multiple sources of air pollution are or were present. Tree cores were collected from trees growing 1 km from both the cement plant and the industrial area that are located 8 km from each other. The analysis of the trace elements was performed on annual tree rings from 1990 to 2016 using laser ablation inductively coupled plasma mass spectrometry. Trace elements Cs, Mg, Mn, S and Zn reflected the emission history of the cement plant. Their values have increased since early 2000s, when the cement plant started its activity. However, the lack of significant trends of pollutants in the tree rings from the industrial area and the possible effect of translocation and volatility of some elements left open questions. The very weak changes of the other trace elements in the period 1990–2016 suggest those elements do not mark any additional effect of the industrial activity on the background pollution. The results confirm that downy oak trees growing close to isolated industrial plants must be considered a pollution forest archive accessible through dendrochemistry.

“…In this research, we have examined tolerance to both organic and inorganic pollutants by a soil saprotrophic fungus, Penicillium griseofulvum Dierckx isolated from a historically polluted soil. The study area was the Italian National Site of Interest "Valle del Sacco" (Lazio, Italy) which is affected by high concentrations of multiple pollutants such as hexachlorocyclohexane, vanadium and lead (Ceci et al 2012;Bernardini et al 2016;Bernini et al 2016). The aims of this research were to evaluate the tolerance/resistance of P. griseofulvum FBL 500 to different combinations of vanadium, lead, and isomers of HCH; to study the inorganic biotransformation in the presence of metals, and possible biomineralization phenomena; and to analyse biodegradation of an isomeric mixture of HCH, in the absence and in the presence of vanadium, and the impact of any synergistic effects on fungal metabolism.…”

The saprotrophic fungus Penicillium griseofulvum was chosen as model organism to study responses to a mixture of hexachlorocyclohexane (HCH) isomers (α-HCH, β-HCH, γ-HCH, δ-HCH) and potentially toxic metals (vanadium, lead) in solid and liquid media. The P. griseofulvum FBL 500 strain was isolated from polluted soil containing high concentrations of HCH isomers and potentially toxic elements (Pb, V). Experiments were performed in order to analyse the tolerance/resistance of this fungus to xenobiotics and to shed further light on fungal potential in inorganic and organic biotransformations. The aim was to examine the ecological and bioremedial potential of this fungus verifying the presence of mechanisms that allow it to transform HCH isomers and metals under different extreme test conditions. To our knowledge, this work is the first to provide evidence on the biotransformation of HCH mixtures, in combination with toxic metals, by a saprotrophic non-white-rot fungus and on the metabolic synergies involved.
