“…In particular, Raman spectrum shows (Figure 5b) the characteristic bands at 683, 377 and 230 cm −1 [62,63]. Other serpentine minerals such as lizardite and polygonal serpentine were not found, which is consistent with previous findings [15,42,43]. Figure 5c shows the points analyzed on metabasite using p-µR which revealed the presence of amphiboles.…”

“…The crystallinity, chemistry, thermal behavior, and other characteristics of minerals found in inactive serpentinite and metabasite quarries have already been reported [15,42,43]. Collected p-µR spectra as p-XRF spectra, were conducted exclusively on fibrous morphologies found inside the serpentinite and metabasite veins, observed using p-DM and Raman microscope.…”

“…In Europe and several other countries, the asbestos prohibition laws [9] banning the use of asbestos fibers have reduced the number of workers currently exposed to asbestos. However, asbestos fibers can be hosted in serpentinite or metabasite rocks whose outcrops are known as naturally occurring asbestos (NOA) [10][11][12][13][14][15]. Until the enactment of laws [9,16], which regulates the extraction, processing and use of rocks containing asbestos fibers, these rocks were quarried and used indiscriminately for various purposes.…”

“…To achieve this ambitious goal, we cross-checked the data obtained from the p-DM, p-XRF and p-µR on the serpentinites and metabasites outcropping in the Gimigliano-Mount Reventino Unit (GMRU) [14,41]. Previous studies [15,42,43] [28]. The toxicology of chrysotile, such as tremolite asbestos, is associated with size, durability, and chemical composition [27,44,45].…”

An innovative and, as yet, untested approach is to analyze serpentinite and metabasite rocks containing asbestos using a portable multi-analytical device, which combines portable digital microscopy (p-DM), portable X-ray Fluorescence (p-XRF) and portable micro-Raman Spectroscopy (p-µR). The analyses were carried out in two inactive quarries of serpentinitic and metabasitic rocks from the Gimigliano-Mount Reventino Unit (Southern Italy) already characterized in previous studies, with the aim of testing the efficiency of these portable tools. In this study, a portable X-ray fluorescence analyzer was used to obtain the in situ rapid chemical discrimination of serpentinite and metabasite rocks. The characterization of outcropping rocks using portable devices enabled us to detect the presence of chrysotile and asbestos tremolite. The results obtained were consistent with the findings from previous research studies and therefore combining p-DM, p-XRF and p-µR could be a useful approach for discriminating asbestos contained in outcropping rocks, especially when sampling is prohibited or for field-based sampling.

The Nevado-Filábride Complex (NFC) area (southern Spain) is well known for the widespread mining and quarrying activities. Serpentinite and metabasite rock types are extracted, processed and traded as building and ornamental stones. Due to possible presence of Naturally Occurring Asbestos (NOA) minerals in these lithotypes, the aim of the investigation of this paper is to discern about the presence of these fibrous minerals and to characterize them in detail. In order to do this, seven serpentinite rock samples were collected in four quarries located in Sierra Nevada and Sierra de los Filabres (South-eastern Spain) and studied by X-ray powder diffractometry (XRPD), Scanning Electron Microscopy combined with Energy-Dispersive Spectrometry (SEM/EDS), Differential scanning calorimetry (DSC), Derivative Thermogravimetry (DTG) and by X-ray Synchrotron microtomography (SR-µCT). The investigation of asbestos minerals is very important not only from a scientific point of view, but also from a legislative one, especially for the administrative agencies that have to take decisions with regards to the implementation of health protection to workers (e. g., quarry excavations, road yards, civil constructions, building stones).
