“…Reviewing asbestos and mesothelioma publications from LA countries, we found several descriptive case series studies [707172737475767778]. Few studies presented mesothelioma mortality estimates for the region, presumably because data to all LA countries were unavailable, unreported, or limited in quality and coverage.…”

“…After decades of heavy asbestos use, Argentina instituted a national ban in 2001 [72]. Using WHO data, Park et al [83], reported that from 1994 to 2008, a total of 1,065 mesothelioma deaths were registered in Argentina – 97 per year in average.…”

“…Pasetto et al [19], used the Cancer Exposure (CAREX) database to calculate the proportion of exposed workers to asbestos by trade in Argentina, Brazil, Colombia, and Mexico. In LA countries, the scarcity of data led researchers to use asbestos consumption calculated from the volume of asbestos extraction, trade, imports, and exports as aggregated proxy information on exposure to be used in descriptive [72] or ecological analysis [82].…”

Background: Asbestos consumption in Latin America (LA) amounts to 10% of yearly global production. Little is known about the impact of asbestos exposure in the region. Objective: To discuss scientific and socio-economic issues and conflicts of interest and to summarize epidemiological data of asbestos health effects in LA. Discussion: Recent data on chrysotile strengthened the evidence of its carcinogenicity and showed an excessive risk of lung cancer at cumulative exposure levels as low as 1.5 fibre-years/ml. Technology for substitution is available for all asbestos-containing products and ceasing asbestos production and manufacturing will not result in unemployment and loss of income, except for the mining industry. The flawed arguments used by the industry to maintain its market, both to the public and in courtrooms, strongly relies on the lack of local evidence of the ill effects and on the invisibility of asbestos-related diseases in LA, due to the limited number of studies and the exposed workers’ difficulty accessing health services. The few epidemiological studies available show clear evidence of clusters of mesothelioma in municipalities with a history of asbestos consumption and a forecasted rise in its incidence in Argentina and Brazil for the next decade. In Brazil, non-governmental organizations of asbestos workers were pivotal to counterbalance misinformation and inequities, ending recently in a Supreme Court decision backing an asbestos ban. In parallel, continuous efforts should be made to stimulate the growth of competent and ethical researchers to convey adequate information to the scientific community and to the general public.

“…In Argentina most asbestiform minerals are associated with metamorphosed and/or metasomatized mafic and ultramafic igneous rocks, mainly serpentinites and amphi bolic rocks, talc and vermiculite deposits as well as with dolomitic rocks (Angelelli et al 1980;Locati et al 2014;Lescano et al 2016a). Their production started in 1920, stimulated by the industrial use of asbestos in postwar years, but they have been banned since 2003 (Rodriguez 2004). However, asbestos research is still important in Argentina because many active mines and future projects can poten tially incorporate asbestiform fibers during the exploitation works (e.g., serpentinite, talc, vermiculite and carbonate deposits).…”

In Argentina, asbestos is associated with meta-mafic or meta-ultramafic igneous rocks, mainly serpentinites (or steatized varieties) and amphibolites, and less commonly with dolomitic rocks (in metamorphic and metasomatic domains). Chrysotile, anthophyllite and tremoliteactinolite were identified as the main asbestiform minerals (in the range of respirable particles). Chrysotile occurs mainly in serpentinites or steatized rocks as well as in amphibolites and other host rocks nearby. It appears filling veins, as slip and cross-fiber, generally associated with fissures or shear zones. Amphibole asbestos, mainly from the tremolite-actinolite series and anthophyllite, commonly occurs together with a non-asbestiform coun terpart within the same area and deposits. These minerals have been found in talc ores as well as in vermiculite-rich sectors, or filling fissures in meta-mafic and meta-ultramafic rocks. In this compilation, the results of case studies on mines from the provinces of Cordoba, Mendoza and San Juan (Argentina) are summarized, and

“…Sepiolite is a naturally occurring phyllosilicate, of fibrous habit, whose structure consists of channels running parallel to the fibres, called zeolitic channels, which are responsible for most of its properties, among them its absorbing capacity (Jones and Galán 1988). The morphology of sepiolite has sparked scientific debate due to its toxicity and it may be included in the asbestos group in future regulatory legislation (Rodríguez 2004).…”

Asbestiform minerals, namely serpentine (chrysotile) and amphiboles (tremolite-actinolite) as well as others of fibrous habit (sepiolite) from Argentine deposits were characterised to assess their biological hazard. Materials currently used as asbestos substitutes were also assessed (glass fibre and ceramic fibre). Studies with laboratory animals were conducted. Sixty mice (30 females and 30 males), 8 weeks old, were used following the good practices in the care and handling of laboratory animals. They were split into six groups of ten mice each (5 females and 5 males), designated as control, tremolite, glass fibre, chrysotile, sepiolite and ceramic fibre, and were exposed by inhalation to these previously ground materials. The animals were examined throughout the experiments to see how they responded to the inhaled substances to establish the effects of inhalation at the time of exposure and once they had been killed. The respiratory tract (trachea, bronchi and lungs) of the animals exposed to the different materials was examined in tissue sections. Differences in the amount of connective tissue in the lungs and the presence of alveolar macrophages were observed in the animals exposed to tremolite, chrysotile and sepiolite, as compared to the control group. It was concluded that, of all the materials used, amphiboles caused greater damage and an incipient development of carcinogenesis. The other ones, especially chrysotile, produced connective tissue thickening.
