Asbestos argentinos y sustitutos : degradación, movilidad y potencial riesgo para la salud

Lescano, Leticia 08 March 2013 (has links)
El amplio espectro de aplicaciones industriales de los asbestos, las restricciones cada vez más rigurosas que llevaron a la prohibición total de su uso y comercialización, condujeron a desarrollar un plan de investigación que culminó con la ejecución de este trabajo de Tesis.Se trabajó en yacimientos argentinos, en los que la bibliografía citaba la presencia de minerales asbestiformes. Estos constituyen la mena objeto de explotación o bien aparecen como impurezas o son complementarios. Es por ello que se realizó un estudio detallado de asbestos desde el punto de vista mineralógico y morfológico. Se trabajó con minerales del grupo de la serpentina, anfíboles, sepiolita y actuales sustitutos tales como fibra de vidrio y cerámica.Se identificaron minerales asbestiformes como crisotilo, en yacimientos en explotación, abandonados y en escombreras en cercanías a zonas habitadas. Se evaluó el comportamiento de estos minerales en diferentes condiciones ambientales tales como degradación en medio ácueo o en la atmósfera y se comprobó que pueden modificar su tamaño hasta alcanzar los nocivos para la salud humana.En la provincia de Mendoza se han explotado yacimientos de talco donde se menciona la presencia de anfíboles aunque no han sido estudiados desde el punto de vista de su contaminación. A partir de los estudios realizados tanto en los frentes activos de las canteras como en las escombreras, se determinó que los anfíboles presentan diferentes morfologías y se reconocieron hábitos asbestiformes nocivos para la salud. También se evaluó la presencia de anfíboles como impurezas, en minas de vermiculita en explotación. Estos minerales, además de ser movilizados en la etapa extractiva, son sometidos a tratamientos térmicos para provocar su expansión, liberándose de la masa micácea y quedando en el residuo del horno o liberado al aire desde las chimeneas de las plantas que se encuentran en zonas pobladas. Por diferentes métodos analíticos (DRX, microscopía de polarización, SEM y EDS), se confirmó que los anfíboles presentes en las minas de vermiculita estudiadas, corresponden a la serie tremolitaactinolita. Estos se observaron en todas las muestras analizadas, tanto en las obtenidas de las vetas en producción, como en los diferentes estadios de procesamiento en las plantas de tratamiento. A su vez, se observó una disminución en el contenido de anfíboles a medida que avanza el proceso ya que se recuperan los productos livianos. Se realizaron experiencias con animales de laboratorio expuestos a asbestos (anfíboles y crisotilo de yacimientos argentinos), sus actuales sustitutos (fibras cerámica y de vidrio) y sepiolita. Se estudiaron los pulmones con la colaboración de especialistas en el tema. Teniendo en cuenta que la exposición no fue prolongada y que la inhalación no fue continua, los resultados obtenidos fueron positivos mostrando alteraciones internas especialmente en ratones expuestos a actinolita-tremolita y crisotilo. Las controversias mencionadas en la bibliografía respecto a la toxicidad de la sepiolita, llevaron a estudiar sus similitudes morfológicas con los minerales asbestiformes, especialmente con el crisotilo. Los resultados obtenidos en los estudios toxicológicos permitieron concluir que el mineral no es nocivo para la salud. Por ello se estudiaron posibles aplicaciones industriales con sepiolitas argentinas. Con diferentes técnicas como, liofilización, ultrasonido y tratamientos ácidos, se comprobó que el mineral puede procesarse de modo sencillo y ser usado con alto valor agregado en distintas industrias de nuestro país.Por último, se evaluó la presencia de asbestos en materiales de construcción en un edificio antiguo en Ing. White. Se determinaron dos tipos de asbesto: crisotilo y amosita. El primero fue identificado en placas de fibrocemento y el segundo como aislante en tuberías. / The wide range of industrial applications for asbestos minerals and increasingly rigorous constraints leading to the ban on their use and commercialization concluded in a research plan for the present Thesis. Studies were conducted in Argentinean deposits which, according to literature, present asbestiform minerals. These minerals constitute the ore object of exploitation or occur as impurities or accessories. The studied deposits are generally abandoned and their degradation can generate health problems or constitute an environmental passive. Therefore, a detailed mineralogical and morphological study of the asbestos was conducted using minerals from the group of the serpentine amphiboles, sepiolite and current substitutes such as ceramic and vitreous fibers. Asbestiform minerals such as chryisotile were identified in active and abandoned mines and in tailings near inhabited areas. The behavior of these minerals in different environmental conditions, such as degradation in water or atmosphere, was evaluated and it was checked that they can modify their size, reaching the harmful to human health. In the province of Mendoza talc mines have been exploited where the presence of amphiboles is mentioned, although they are not been studied related with their contamination. From the studies realized in this work both in quarry active fronts as in tailings it was determined that amphiboles have different morphologies and asbestiform habits harmful to health have been recognized The presence of amphiboles as impurities in active vermiculite mines was also evaluated. These minerals are subjected to thermal treatments to generate their expansion, and are mobilized in the extraction stage, releasing themselves from the mica and remaining in the residue of the oven or released to the air from the smokestacks of the plants located in the urban zones. Using different analytical methods (XRD, light microscopy, SEM and EDS) it was confirmed the amphiboles present in the vermiculite mines studied are tremolite – actinolite. They were observed in all the samples studied, both from the veins in production as in the different processing stages in treatment plants. Also a decrease in the amphibole content with the progress of the process was observed because the light products are recovered. Experiments with laboratory animals exposed to asbestos (amphiboles and chrysotile from argentine mines), its current substitutes (ceramic and vitreous fibers) and sepiolite were conducted. Their lungs were studied with the cooperation of experts. Considering the exposition wasn´t prolonged and the inhalation wasn´t continuous, the results were positive showing inner alterations mainly in mice exposed to tremolite – actinolite and chrysotile. The controversies related with the toxicity of sepiolite mentioned in the bibliography, carried to study their morphological similarities with asbestiform minerals, mainly with chrysotile. The results obtained in the toxicological study allowed concluding that the mineral is not harmful to health. Therefore possible industrial applications with argentine sepiolite were studied. Using different methods such as lyophilization, ultrasound and acid treatment, is was tested that the mineral can be processed in a simple way and to be used with high added value in different industries in our country. The presence of asbestos in construction materials in an old building in Ing. White was evaluated. Two types of asbestos were determined: chrysotile and amosite. The first was identified in fibercement sheets and the second as insulating in pipes.

Bioecología y relaciones interespecíficas en poblaciones de dos algas pardas del Atlántico Occidental Sur y Norte: Dictyota dichotoma y Ascophyllum nodosum

Gauna, María Cecilia 18 March 2006 (has links)
Esta tesis representa el primer estudio integral sobre epifitis-mo en una población de Phaeophyceae en la Argentina. A nivel mundial es el primero sobre epifitismo del género Dictyo-ta y de la especie D. dichotoma. En ella se estudiaron aspec-tos de la bioecología y las relaciones interespecíficas de dos poblaciones de macroalgas bentónicas de la clase Phaeophy-ceae del Atlántico Occidental Sur y Norte respectivamente: Dictyota dichotoma y Ascophyllum nodosum. En la población de D. dichotoma el objetivo general fue analizar la bioecología y la fenológía en las costas de Argentina y evaluar sus in-teracciones epifíticas. En población de A. nodosum, el objeti-vo general fue evaluar el impacto de Vertebrata lanosa (su principal epífito) sobre sus parámetros vegetativos y reproduc-tivos. Los objetivos específicos en la población de D. dichoto-ma fueron: confirmar la identidad de los especímenes, descri-bir la morfología vegetativa y reproductiva, determinar su diná-mica poblacional, evaluar la carga epifítica, en cuanto a su di-versidad biológica, su variación espacio-temporal y la posible existencia de distribuciones longitudinales sobre el talo hospe-dador. Los objetivos específicos enunciados para la población de A. nodosum fueron: evaluar el efecto de la presencia de V. lanosa sobre parámetros vegetativos y reproductivos en la población infectada, comparándolos con los de población libre de simbiontes, diseñar un experimento a campo que nos permi-ta evaluar parámetros comparables en talos con y sin filamen-tos de V. lanosa. Por último, comparar algunos de los paráme-tros analizados en común en ambas poblaciones de hospeda-dores. Las muestras de D. dichotoma fueron recolectadas de las regiones submareales de las Grutas, Provincia de Río Ne-gro, Argentina y las de A. nodosum desde Tor Bay Park, Nova Scotia, Canadá. En esta tesis, fue posible confirmar la identi-dad de D. dichotoma y su distribución geográfica fue exten-dida hacia el norte hasta los 4043′S. En general, las variables morfológicas y reproductivas analizadas sobre sus talos, varia-ron estacionalmente, presentando valores máximos durante las estaciones primavera y verano. La población de talos no fértiles y de talos esporofíticos fueron los que presentaron mayor variabilidad estacional, posiblemente por su escasa re-presentación en la muestra. La población de D. dichotoma es-tuvo constituida principalmente por talos gametofíticos feme-ninos y masculinos, en menor proporción estuvieron represen-tados los talos esporofíticos y no fértiles. Su fenología repro-ductiva se caracterizó por un mayor número de gametófitos femeninos durante el verano y con proporciones relativamente cercanas de talos gametofíticos femeninos y masculinos du-rante el otoño - invierno. La generación esporofítica fue muy escasa gran parte del año, e incluso ausente en meses deter-minados. D. dichotoma se caracterizó por un ciclo constituido por un patrón básicamente sexual, constituido por gametófi-tos masculinos y femeninos. Las diferentes estructuras repro-ductivas se formaron en mayor cantidad en las regiones apica-les de la macroalga. Los talos gametofíticos masculinos y femeninos estuvieron más reproductivos-formación máxima de órganos reproductivos durante la primavera -verano. D. dicho-toma, estuvo colonizada por 37 organismos epifitos, siendo las diatomeas las de mayor representación. Las especies epífitas más abundantes fueron: Microchaete auriginea, Calothrix fus-ca, Grammatophora marina, Cocconeis sp., Stylonema alsidii, Audouinella secundata, Polysiphonia sp. y Acrochaete mar-chantiae. Durante enero se observó mayor cantidad de Phylla representados sobre el hospedador y en agosto la mayor a-bundancia de epífitos, dado por altas presencias de G. marina, M. auriginea y Cocconeis sp. Durante mayo se presentaron las abundancias mas bajas, estando principalmente representada por S. alsidii. Durante la primavera se evidenció la mayor car-ga epifítica, determinada por M. auriginea. Las secciones me-dias de los talos hospedadores, se diferenciaron de las apica-les y basales por su mayor número de Phyllum representados, un mayor número de organismos epifitos y mayor carga epi-fítica, la cual estuvo principalmente dada por la presencia de G. marina, Cocconeis sp. y M. auriginea. El mayor grado de epifitismo fue en invierno, mientras que en las otras dos regio-nes fue observado durante la primavera. Además, fue observa-do un gradual aumento desde la sub - sección 1 a la 5 en las 3 regiones de los talos del hospedador. Sobre la población de A. nodosum la mayoría de variables morfológicas y reproduc-tivas de fueron mayores sobre la población epifitada por V. lanosa. Se evidenció, una alta correlación positiva entre el número de matas de V. lanosa y el peso seco de A. nodosum y entre el peso seco del epífito rojo y el número de ramas ro-tas del hospedador. / This thesis represents the first integral study about epiphy-tism in a Phaeophyceae population in Argentina. In global level, it is the first study about epiphytism o Dictyota Genus and D. dichotoma species. In this study were determi-nate topic about bio-ecology and inter-specific relationship, in two Phaeophycean populations from North and South Occiden-tal Atlantic. Two benthic seaweeds were selected: Dictyota dichotoma and Ascophyllum nodosum. On the D. dichotoma population, was enunciated as general aim, to analyze the bio-ecology and phenology from Argentinian population and to evaluate the epiphytic interactions. On the A. nodosum popu-lation, the general aim was evaluate the impact of Vertebrata lanosa (its epiphyte main) on both vegetative and reproduc-tive parameters of the host population. The specific aims on D. dichotoma population were: to confirm the identity of specimens, to describe the both vegetative and reproductive morphology, to determinate its population dynamic, to evalua-te the epiphytic load, in its biological diversity, its space temporal variation and a possible existence of longitudinal distributions on the host frond. The specific aims enunciated on A. nodosum population were: to evaluate the effect of V. lanosa on both vegetative and reproductive parameters in infected A. nodosum population, comparing them with the parameters of free symbionts population, to design a experi-ment in field, which led us to evaluate comparable parameters in thalli wich V. lanosa removed and infected. Finally, to compare some analyzed aspects in both hosts populations. D. dichotoma samples were collected from subtidal regions in Las Grutas, Río Negro Province, Argentina and y A. nodosum samples from Tor Bay Park, Nova Scotia, Canada. In this the-sis, was possible confirm the identify of D. dichotoma and its geographic distribution was extend to the north to 4043′S. In general, the both morphologic and reproductive variables analyzed on its thalli, seasonal varied presenting maximum values during spring and summer. The thalli population non-fertile and sporophytic thalli presented higher variation in the sample. D. dichotoma population was constituted mainly by female and male gametophytic thalli, in lower proportion were represented sporophytic and non - fertile thalli. The reproduc-tive phenology was characterized by a higher number of fema-le gametophytic during summer and with proportions relatively near of female and male gametophytic thalli during autumn and winter. The esporophytic generation was not very abun-dant in majority of the year and even was absent en some months. D. dichotoma was characterized by a life cycle cons-tituted by a basically sexual pattern, formed by both female and male gametophytic. The different reproductive structures were formed mainly in seaweeds apical regions. The male and female gametophytic thalli were more reproductive maximum formation of reproductive organs-during spring - summer. D. dichotoma, was colonized by 37 epiphytic organims, being the diatoms which had higher representation. The epiphytes spe-cies more abundant were: Microchaete auriginea, Calothrix fusca, Grammatophora marina, Cocconeis sp., Stylonema alsidii, Audouinella secundata, Polysiphonia sp. and Acrochaete marchantiae. During January was observed a higher number of Phylum on the host and in august the higher abundance of epiphytes, by higher presences of G. marina, M. auriginea and Cocconeis sp. During May were observed the lower abundan-ces, its being representated mainly by S. alsidii. During spring was observed the higher epiphytic load, determinate by M. auriginea. The medial sections oh host thalli, were differen-tiated of the both apical and basal by its higher number of Phylum, a higher number of epiphytic organisms and a higher epiphytic load, which was mainly represented by G. marina, Cocconeis sp. and M. auriginea. The higher degree of epiphy-tism was in winter, while in other two regions was observed during spring. Also, was observed a gradual increase from the subsection 1 to 5 in the three regions of host thalli. On the A. nodosum population, the majority of morphological and re-productive variables were higher on the epiphyted population by V. lanosa. It was observed, a positive correlation high between the number of V. lanosa and A. nodosum dry mass and between the V. lanosa dry mass and the number hosts broken branches.

Envejecimiento poblacional y políticas de vejez : el caso argentino

Giménez, Mabel N. 15 April 2013 (has links)
El envejecimiento será el rasgo característico del paisaje demográfico mundial del s. XXI, y afectará profundamente los distintos aspectos de la vida humana, tanto individual, comunitaria, nacional e internacional. Constituye un fenómeno inédito en la historia de la humanidad y como consecuencia de transformaciones culturales, sociales, políticas y económicas que inciden en la disminución de las tasas de fecundidad y mortalidad. La relevancia del tema a nivel global llevó a Naciones Unidas a convocar a dos Asambleas, la primera en Viena en el año 1982 y la segunda en Madrid en el año 2002. Durante ésta se redactaron dos documentos oficiales: la Declaración Política, donde se estableció el compromisos de los Gobiernos para responder a los desafíos que plantea el fenómeno a las formas de organización social, económica y cultural, y el Plan de Acción Internacional para el Envejecimiento (PAIME), instrumento programático que propone recomendaciones en tres áreas prioritarias: las personas de edad y el desarrollo, el fomento de la salud y el bienestar en la vejez, y la creación de un entorno propicio y favorable a las personas de edad. Durante la Conferencia Intergubernamental sobre Envejecimiento que se celebró en Santiago de Chile en 2003 los países de América Latina y el Caribe acordaron la Estrategia Regional para la implementación del PAIME. En la Argentina el envejecimiento demográfico es una tendencia que se observa desde la década del setenta. Según el Censo Nacional de Población de 2010 el porcentaje de población de 60 años o más era de 13,4%; de acuerdo a la Comisión Económica para América Latina y el Caribe (CEPAL) integra junto a Cuba y Uruguay el grupo de países de envejecimiento avanzado de la región. La investigación tiene como objetivos: i) estudiar el envejecimiento poblacional argentino en el marco del proceso de transición demográfica mundial; ii) analizar el perfil socio-demográfico y la situación de salud de la población adulta mayor de la Argentina; iii) caracterizar el andamiaje institucional nacional desplegado para el tratamiento del tema; iv) describir las formas en que las políticas públicas nacionales se encaminan para dar cumplimiento de las directrices y lineamientos internacionales en materia de envejecimiento poblacional y vejez. De la investigación se concluye que la Argentina está registrando avances en relación a la atención de las demandas por protección y seguridad de la población adulta mayor; sin embargo, dado que el envejecimiento demográfico es un fenómeno dinámico que está en continuo desarrollo, el Estado deberá llevar a cabo múltiples acciones para disponer de nuevas estructuras, incrementar capacidades y reasignar recursos que posibiliten enfrentar exitosamente los desafíos que el mismo impone. / ABSTRACT Population ageing will be the main characteristic of the world’s demographic interest in the twenty-first century, affecting radically different aspects of life, from an individual point of view as well as from a communitarian, national and international one. This is an entirely new phenomenon in the history of humanity and is the direct consequence of cultural, social, political and economical transformations that have reduced the fecundity and mortality rates. The United Nations summoned two Assemblies to discuss this relevant global matter, the first one in Viena (1982) and the second in Madrid (2002).Second World Assembly on Ageing adopted two key documents: a Political Declaration and the Madrid International Plan of Action on Ageing, a document that proposes recommendations in order of priority in three directions: elder population and development, advancing health and well-being into old age and ensuring enabling and supportive environments. The Latin American and Caribbean countries agreed to a Regional Strategy for the Madrid Plan of Action implementation during the Intergovernmental Conference on Ageing that took place in Santiago de Chile (2003). In Argentina, population ageing is a tendency observed since 1970. The 2010 National Census showed that the proportion of people aged 60 or over was of 13,4%; Argentina being one of the countries with the greatest rate of elderly people in the region according to the Economic Commission for Latin America and the Caribbean (ECLAC). This paper has the following objectives: 1) study the Argentina population ageing in the process of the worldwide demographic transition; 2) analyze the social and demographic profile and the health situation of the ageing population in Argentina; 3) characterize the national institutional structure developed to face the problem; 4) describe the steps followed by the national public policies to fulfil international aims about population aging and elder people. The analysis shows that Argentina is improving its attention to the demands for protection and security of the ageing population; but considering that demographic ageing is a dynamic phenomenon in a continuous development, the State will have to dispose of new structures, increase capacities and redistribute resources to face the new challenges successfully.

From craft to flexibility: linkages and industrial governance systems in the development of a capital-goods industry in Mendoza, Argentina, 1895-1990

Borello, José Antonio 22 May 2007 (has links)
This thesis examines the development of a capital goods industry in Mendoza Argentina through an analysis of linkages and industrial governance systems. Linkages are material, informational, and financial flows among firms. Industrial governance systems are the social practices that cement linkages. Hence, linkages are understood as socially embedded and not as market transactions governed solely by price considerations. The study has two major arguments. First, it claims that contrary to conventional industrial location theory firms do not locate in view of the previous existence of certain favorable factors, but rather construct these factors as they grow. This argument is operationalized by asking how firms generate in time their own linkages. Examples taken from the 1895-1990 period include labor and subcontractors, clientele, services, and the emergence of economic groups. Second, this study argues that the capital-goods industry in Mendoza is undergoing a Substantial (and unprecedented) transition in the way production is organized. The transition is part of the larger shift taking place at both the national and global scales. The analysis focuses on the historical pattern of linkages and governance systems in the industry, and contrasts that pattern with that of the recent decade. Implicit in the previous two arguments are two territorial dimensions. First, the development of “industry produces regions" (Storper and Walker 1989). Second, at the intra-city level this means that the evolution of the industry (and specifically its linkage structure and governance systems) has a direct bearing on the direction and nature of the city’s growth. These two arguments are illustrated through empirical work in Mendoza, a city of close to a million people in western Argentina. Over 100 interviews gathered over ten months reveal the origins, evolution, and current form of linkages in the capital-goods industry. These interviews are complemented by data from a variety of sources. The main conclusions of the study are three. First, the study illustrates the richness and depth that emerges from a project based on substantial fieldwork. Second, it shows the advantages of conceiving industrialization not as the location of plants in response to favorable conditions, but as a process initiated by the firms themselves. Third, the dissertation shows that the capital-goods industry of Mendoza iS in a transitional phase towards new ways of organizing production. The transition is expressed in new linkage structures, new governance systems, and the emergence of new types of firms and institutional arrangements. / Ph. D.

Local environmentalism in a globalized world : a case study of the international environmental discourse and Nahuel Huapi, Argentina

Gruber, Vanessa Simone January 2008 (has links)
Thesis (B.A.)--Boston University. University Professors Program Senior theses. / PLEASE NOTE: Boston University Libraries did not receive an Authorization To Manage form for this thesis. It is therefore not openly accessible, though it may be available by request. If you are the author or principal advisor of this work and would like to request open access for it, please contact us at open-help@bu.edu. Thank you. / This paper analyzes the relationship between the global discourse on the environment and the discourse occurring in Nahuel Huapi, Argentina over the 20th century through the year 2007. This paper applies discourse analysis theory as used by Antonio Gramsci and Michel Foucault to the history of environmental discourse on a global, national, and local level. It assesses the institution of language and dialog through personal narrative , metaphor, rhetorical devices, and formal documentation in order to interpret the ways in which global environmental discourse has reached Nahuel Huapi. The primary examples of global discourse used are historical accounts by environmental sociologists , histories of the United Nations' incorporation of environmental discourse , and anthropological accounts of the global indigenous discourse. National linkages are made through studies of international treaties ratified by the Argentine government and laws implemented throughout the state. Local linkages are further made through anthropological assessments of local discourse as well as personal interviews . I analyze the global, national and local discourses in that order with a chronological focus throughout. Existing analyses of environmental institutions and their effectiveness tend to focus on the formal proceedings of international organizations, private citizens , or community actors but most fail to assess the informal mechanisms by which these global institutions can affect action at the local level. By arguing that language and dialog are indeed socialand political institutions, I conclude that through discourse, the international environmental regime has strongly affected local environmental discourse in Nahuel Huapi Argentina through two channels: 1) the National Parks System, which the international regime has impacted mainly through United Nations forums such as conferences and summits on the environment and development. 2) The Mapuche community , which the international regime has impacted mainly through the inclusion of indigenous communities in the international forum and the legitimization that the United Nations provides these communities with regard to environmental stewardship and selfdetermination. The study shows that early in the 20th century, when the Mapuche community and the government of Argentina were isolated from any global discourse , the dialog between them was virtually non-existent.
