“…The knowledge of the partitioning behavior of trace elements between amphiboles and/or serpentines and melt is important for understanding lithospheric processes. The finding of relatively high concentrations of trace metals in the samples of chrysotile and amphiboles is in agreement with the literature data, which shows that in soils derived from serpentinite, the detected metals (Mn, Cr, Co, Ni) are present in high amounts (Bloise et al, 2016b;Lyon et al, 1968Lyon et al, , 1970Schreier, 1987;Smith et al, 2007).…”

Both occupational and environmental exposure to asbestos-mineral fibres can be associated with lung diseases. The pathogenic effects are related to the dimension, biopersistence and chemical composition of the fibres. In addition to the major mineral elements, mineral fibres contain trace elements and their content may play a role in fibre toxicity. To shed light on the role of trace elements in asbestos carcinogenesis, knowledge on their concentration in asbestos-mineral fibres is mandatory. It is possible that trace elements play a synergetic factor in the pathogenesis of diseases caused by the inhalation of mineral fibres. In this paper, the concentration levels of trace elements from three chrysotile samples, four amphibole asbestos samples (UICC amosite, UICC anthophyllite, UICC crocidolite and tremolite) and fibrous erionite from Jersey, Nevada (USA) were determined using inductively coupled plasma mass spectrometry (ICP-MS). For all samples, the following trace elements were measured: Li, Be, Sc, V, Cr, Mn, Co, Ni, Cu, Zn, As, Rb, Sr, Y, Sb, Cs, Ba, La, Pb, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Th, U. Their distribution in the various mineral species is thoroughly discussed. The obtained results indicate that the amount of trace metals such as Mn, Cr, Co, Ni, Cu and Zn is higher in anthophyllite and chrysotile samples, whereas the amount of rare earth elements (REE) is higher in erionite and tremolite samples. The results of this work can be useful to the pathologists and biochemists who use asbestos minerals and fibrous erionite in-vitro studies as positive cyto- and geno-toxic standard references.

“…The units belonging to the External Ligurides also crop out in Emilia and Tuscany and are commonly included in marls and sandstones. Asbestos minerals are also found in the southern segment of the Apennines in the ophiolitic sequence along the Calabrian-Lucania border and in northern Calabria, in the Sila Piccola area [25,26]. Asbestiform amphiboles occur in the benmoreitic lavas of Monte Calvario and belong to the Etna volcanic complex [27].…”

The Concentration of Asbestos Fibers in Bulk Samples and Its Variation with Grain Size

The aim of this work was to establish whether asbestos fibers homogeneously occur in the different fractions ground from naturally occurring asbestos lithotypes, and to calculate the contribution of fibers from each fraction to the overall concentration in the sample. Serpentinite, metabasalt, calc-schist, clay, debris material, and soil, were addressed. Grain size fractions below 20 mm were sieved at 2 mm and 0.106 mm; they were then were mechanically milled to obtain powders below 0.106 mm. The three powdered fractions were characterized using a scanning electron microscope coupled with energy dispersive spectroscopy following M.D. 06/09/94. The still in use (in some cases), Italian normative M.D. 161/2012 specifies that analyses must be performed on the <2 mm fraction and the concentration (mg/kg) correlated with the weight of the whole sample <20 mm. However, the fiber counts yielded asbestos concentrations 50–60% lower compared with total asbestos analyses according to the new R.P.D. 120/2017. Consequently, there is a need to standardize the normative worldwide regulations for the management of asbestos-containing materials, by re-evaluation of sample preparation and quantification of asbestos.

“…The problem of toxicity and carcinogenicity of asbestos minerals has long been discussed since the 20 century, because it represents a clear consequence for human health. The term asbestos represents a series of six natural asbestiform silicate minerals, which include serpentine (chrysotile), as well as amphibole minerals (tremolite, actinolite, anthophyllite, amosite, and crocidolite that represent a variety of commercial term of fibrous riebeckite) that are defined by law in Europe and in several countries worldwide [1][2][3][4] and also by Italian law (D.Lgs. 2008).…”

In this paper, new mineralogical and petrographical data of asbestiform Magnesio-riebeckite from ophiolite cropping out in the Pollino Unesco Global Geopark (southern Italy) are presented. Magnesio-riebeckite schists with HP-LT index mineral assemblage recorded metamorphic events in blueschist facies in the Frido Unit. Previous toxicological studies showed that asbestiform Magnesio-riebeckite species exhibited high carcinogenicity in previous intraperitoneal injection experiments with rats. The results have been obtained using different analytical techniques such as X-ray fluorescence (XRF), scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS), and electron probe micro analysis (EPMA). Results show that all the samples contain fibrous Magnesio-riebeckite and/or prismatic, acicular crystals in aggregates. The concentration of elements in Magnesio-riebeckite crystals is: Na 2 O (4.12-6.26 wt%), MgO (8.22-10.87 wt%), FeO (19.07-23.81 wt%), SiO 2 (52.05-56.06 wt%), CaO (1.12-4.53 wt%), Al 2 O 3 (1.34-1.93 wt%), and MnO (0.10-0.34 wt%). Magnesio-riebeckite crystals are documented in the Pollino Unesco Global Geopark for the first time. For this reason, the aim of this paper is the characterization of Magnesio-riebeckite to improve the knowledge of this mineral in the studied area, because the release of fibers into the environment is dangerous for human health.
