The disease burden associated with this exposure is difficult to quantify and is not properly investigated. A characterization of the crystal-chemical-physical properties and toxicity/carcinogenicity of naturally occurring fibres with attention to asbestos and erionite is therefore highly recommended. The present study deals with the in vitro biological effects in MeT5A and A549 human cell lines of two non-commercial asbestos fibres: Valmalenco chrysotile from Central Alps Italy and fibrous erionite from Jersey Nevada, USA, including the standards UICC Chrysotile and UICC crocidolite. Light and scanning electron microscopy (SEM) observations showed morphological cell perturbation of treated cells. SEM-EDAX investigations revealed that the release of chemical components in the culture media affect cell viability. ROS levels increased in accordance with glutathione depletion, witnessing a remarkable cellular stress. Free radical release on pristine fibres was investigated by means of electron paramagnetic resonance (EPR) spin trapping technique and FTIR spectroscopy to characterize the molecular structures of fibres. Results reflect the cytotoxic effects and evidence the different toxicity pathways prompted by these fibre species due to their different crystal assemblages and physical properties.

This region has six metallogenetic zones where mining has been documented since ancient times. We study the contents, spatial pattern and natural background of potentially toxic elements (PTEs) of this mining province, to establish the geochemical background variation in the residual soil. The natural (geogenic) contents of PTEs were investigated in the top and bottom residual soil samples. Based on 108 geochemical data, the limits of natural background values (mg & BULL;kg-1) were determined by the integral method: As (38.5), Cd (0.5), Co (36.3), Cu (51.9), Cr (170.1), Hg (0.21), Mn (1974), Mo (0.9), Ni (215.2), Pb (61.7), Sb (2.4), V (84.4) and Zn (116.6). In the horizontal concentration patterns, four groups of PTEs with similar spatial distributions were identified: (As, Pb, Zn); (Cd, Hg, Mo, Sb); (Co, Cr, Ni) and (Cu, Mn, V). Correlation analysis (CA) distinguishes correlations between As-Sb, Co-Cr-Ni, and Cr-Ni. Principle component analysis indicates five different element groups: (Ni, Co, Cr, Mn); (As, Sb, Mo); (Pb, Zn); (Cu, Cd) and (Hg). Our data show that anomalous concentrations of As, Cr, Hg, Ni, Pb, Sb and Mn are geogenic, whereas higher contents of As, Hg, Pb, Sb and Zn in several locations are of a mixed geogenic and anthropogenic origin. Finally, anomalous concentrations of Pb and Zn, when detected outside the area where the ore deposits occur, are purely anthropogenic. LA - English DB - MTMT ER - TY - JOUR AU - Marey, Mahmoud H.H.

AB - We report a petrographic and whole-rock geochemical characterization of the Cenozoic igneous rocks cropping out in the Tafresh area, central Urumieh-Dokhtar Magmatic Arc, NW Iran. The investigated rocks range mainly from basaltic andesite to dacite, and are considered to be genetically linked to a three-step, (mostly) closed-system evolutionary process. It involves first the fractionation of ferromagnesian minerals (mainly clinopyroxene and olivine) and plagioclase, followed by a second removal of plagioclase and lesser amphibole (plus minor clinopyroxene) and eventually, in the most evolved phases, the crystallization of plagioclase with lesser alkali feldspar and minor amphibole. Tafresh rocks define a typical calcalkaline series generated from a subduction-modified mantle wedge, characterized by the classical LILE-enriched and HFSE-depleted compositions. The basaltic andesite magmas do not represent primitive compositions, but are likely derived from an unsampled hydrous primitive melt equilibrated in a spinel-bearing metasomatized peridotite source, evolving at shallow to moderate crustal depths. Additional lithotypes cropping out in the Tafresh area include much rarer strongly evolved leucocratic rocks and evolved rocks with adakitic signature. The first are thought to derive from crustal anatexis of a meta-sedimentary source, whereas the latter are interpreted as the product of the melting of a meta-mafic source rock with residual garnet and amphibole. The association of magmatic rocks pointing to all such different petrogenetic processes in a relatively limited area is strongly suggestive of emplacement in a post-collisional stage.
