“…A factor which is underestimated in fibre toxicity is the content of trace elements, which has been shown to be capable of inducing lung cancer (Bargagli et al, 2008;Baumgardt et al, 1986;Doll, 1958;Edel et al, 1990;Fukuda et al, 2004;Masironi, 1969;Shen and Zhang, 1994;Wei et al, 2014). As a matter of fact, there are both epidemiological and experimental indications that trace elements such as trace metals may provoke lung cancer (IARC, 1993;Nemery, 1990), and some researchers have claimed that asbestos fibres may play a passive role in producing diseases as carriers of trace elements (Dixon et al, 1970;Harington et al, 1967).…”

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.

“…Because of the difference in the composition of various solid wastes, it is necessary to screen out suitable solid wastes to produce fibers. For environmental protection requirements and to avoid human health hazards, the content of heavy metals [ 14 , 15 , 16 ] in solid waste needs to be controlled. Currently in China, the national standards (NSs) for these fibers from solid wastes are still not formulated.…”

Compared to basalt and glass fibers, the production of inorganic fiber from industry solid wastes is an effective method to not only save natural resources but also recycle waste resources. Because the preparation of the fibers requires high temperature treatment, the production process is associated with high energy consumption and high carbon emissions. How to resolve these problems is a current research challenge in this field. Herein, we reviewed the study progress on these fibers and further discussed the key factors determining their characteristics, including chemical composition, melt structure, and viscosity of melt. In production, the matching of solid waste blends containing enough total content of SiO2 and Al2O3, and a suitable amount of MgO and CaO, is beneficial to the structure control of the melt. The study found that the melt consisted of Q2 and Q3; and that Q3 content more than Q2 was more suitable for fiber production and its performance improvement. Such a melt structure can be achieved by controlling the degree of depolymerization and the temperature. New ultrasonic technology can shorten the homogenization time; its application is hoped to save energy and reduce carbon emissions. These conclusions will offer important guidance for the development of inorganic fibers from industry solid wastes in the future.

“…Indeed, there is epidemiologic and experimental evidence that PTEs such as some heavy metals are carcinogens and pose a significant threat to human health (e.g., Nemery, 1990;Censi et al, 2006;4 4 Censi et al, 2011a, b). Moreover, some researchers theorize that asbestos elongate mineral particles may play only a passive role in producing diseases as carriers of trace elements (Dixon et al, 1970;Upreti et al, 1984;Nemery, 1990;Bowes and Farrow, 1997;Wei et al, 2014;Bloise et al, 2016a).…”

“…There has recently been much debate on the role of cancer-causing agents, but it was only in the early 70s that some studies invoked the PTEs as an indicator of asbestos pathogenicity (Cralley et al, 1968;Dixon et al, 1970;Bloise et al, 2016a). It has been proved that high concentrations of trace elements in asbestos are capable of inducing lung cancer (Schreier et al, 1987;Wei et al, 2014). These studies are in agreement with the study conducted by Gazzano et al (2005) who proposed using synthetic stoichiometric chrysotile elongate mineral particles (free of any toxic elements) as a negative control for toxicological studies since synthetic chrysotile elongate mineral particles do not have any in-vitro toxic effects.…”
