Antropoceno, ciências humanas e historiografia / Anthropocene, human sciences and historiography

Resumo O artigo mostra, inicialmente, como as discussões sobre o Antropoceno têm se deslocado de maneira cada vez mais significativa para o campo das ciências humanas. Em seguida, tomando como ponto de partida a proposta de que as ciências humanas deveriam contribuir para a compreensão do "metanível consequencial" dos estudos sobre o Antropoceno, discute como alguns trabalhos produzidos nesse campo têm lidado com as relações entre causas, efeitos e consequências diante das condições do novo regime planetário, considerando de maneira especial as discussões sobre a "tecnosfera". Conclui indicando o potencial das novas perspectivas ontológicas das ciências humanas para a ampliação dos horizontes explicativos e comunicativos da historiografia.

Abstract The article initially presents an increasingly significant move of discussions about the Anthropocene towards humanities and social sciences. Then, taking as a starting point the proposal that these fields could contribute to the understanding of the "consequential meta-level" of studies on the Anthropocene, it discusses how some works produced in humanities and social sciences have dealt with the relationship between causes, effects and consequences regarding the new planetary regime, with a special focus on the debate about the "technosphere." It concludes by indicating the potential of the "ontological turn" to expand the explanatory and communicative horizons of historiography.

O novo regime climático do Antropoceno e de Gaia / The new climatic regime of Anthropocene and Gaia / El nuevo régimen climático del Antropoceno y de Gaia

Resumo O artigo discute os conceitos de Antropoceno e de Gaia, apontados por Bruno Latour como categorias para entender o regime climático que estamos vivendo e servir de base teórica para buscar respostas apropriadas para a crise do clima. Os conceitos buscam superar dois pressupostos da racionalidade moderna: a oposição entre natureza e cultura - questionando o princípio de que os humanos são os únicos atores da realidade e introduzindo todos os seres vivos como agentes conformadores do ambiente - e a visão globalizante do planeta Terra, que impede de ver a terra como solo localizado onde acontecem os ciclos biogeoquímicos de transformação da energia que possibilitam a vida. Conclui-se que a reflexão de Latour fornece bases ontológicas para a discussão sobre a mudança climática e pressupostos para a bioética ambiental.

Abstract This article discusses the concepts of Anthropocene and Gaia, raised by Bruno Latour, as categories to understand the climate regime we are experiencing and serve as a theoretical basis to seek appropriate responses to the climate crisis. These concepts seek to overcome two assumptions of modern rationality: the opposition between nature and culture - questioning the principle that humans are the only actors in reality and introducing all living beings as agents shaping the environment - and the globalizing vision of planet Earth that prevents us from seeing it as localized soil where biogeochemical cycles of energy transformation that make life possible take place. It is concluded that Latour's reflection provides ontological bases for the discussion on climate change and assumptions for environmental bioethics.

Resumen Este artículo discute los conceptos de Antropoceno y Gaia, señalados por Bruno Latour como categorías para entender el régimen climático que estamos viviendo y para servir de base teórica para buscar respuestas adecuadas a la crisis climática. Los conceptos buscan superar dos supuestos de la racionalidad moderna: la oposición entre naturaleza y cultura -cuestionando el principio de que los humanos son los únicos actores de la realidad e introduciendo a todos los seres vivos como agentes conformadores del medio ambiente- y la visión globalizante del planeta Tierra, que impide ver la tierra como un suelo localizado en el que tienen lugar los ciclos biogeoquímicos de transformación de la energía que hacen posible la vida. Se concluye que la reflexión de Latour proporciona bases ontológicas para la discusión sobre el cambio climático y supuestos para la bioética ambiental.

The importance of minerals in medical geology: impacts of the environment on health / La importancia de los minerales en la geología médica: impactos del medio ambiente en la salud

Objective: the purpose of this work is to review research on the role of minerals in Medical Geology, highlighting the importance and interrelationships between geological factors and human health. Materials and methods: qualitative study under the documentary approach from which a review of previous studies on the topic of interest was carried out, taking into account that there is an increasing interest between the health and geoscience communities by elucidating the geologic origins and flow of toxic elements in the environment that lead to human exposure through the consumption of food and water. Results: during the review process of the existing literature, it was evidenced that the advance of science and technology has allowed the opening of new lines of research that require multidisciplinary work with the participation of professionals in different areas of knowledge and the medical geology proposes collaboration between two broad fields of knowledge that apparently have no relationship, such as Earth sciences and biomedical sciences. Several aspects are considered, including the interaction between environment and health, which is very important for an extensive audience, including students, researchers, geological and biomedical professionals, policymakers and general public. Conclusion: medical geology should be considered as a component of the Colombia's National Health Action Plan and therefore, to be most effective the Colombian geoscience community should be included as one of the key players or agencies involved in environmental health studies..Au

Materiales y métodos: estudio de carácter cualitativo bajo el enfoque documental a partir del cual se llevó a cabo una revisión de estudios previos sobre el tópico de interés, teniendo en cuenta que existe un interés creciente entre las comunidades de salud y geociencia al dilucidar los orígenes geológicos y flujo de elementos tóxicos en el medio ambiente que conducen a la exposición humana a través del consumo de alimentos y agua. Resultados: durante el proceso de revisión de la literatura existente, se evidenció que el avance de la ciencia y la tecnología ha permitido la apertura de nuevas líneas de investigación que requieren un trabajo multidisciplinario con la participación de profesionales en diferentes áreas del conocimiento y la geología médica propone colaboración entre dos amplios campos de conocimiento que aparentemente no tienen relación, como las ciencias de la tierra y las ciencias biomédicas. Se consideran varios aspectos, incluida la interacción entre el medio ambiente y la salud, que es muy importante para una audiencia extensa, incluidos estudiantes, investigadores, profesionales geológicos y biomédicos, encargados de formular políticas y público en general. Conclusión: la geología médica debe considerarse como un componente del Plan de Acción Nacional de Salud de Colombia y, por lo tanto, para ser más eficaz, la comunidad de geociencia colombiana debe ser incluida como uno de los actores o agencias clave involucradas en los estudios de salud ambiental..Au

Geological distribution of exudation and storage area of Tibetan medicine Zha-xun in Sichuan province based on GIS / 中国中药杂志

Zha-xun is widely used in Tibetan medicine and is also an international traditional medicine. This study believes that the black organic matter constituting Zha-xun is mainly stored in the rocks. The exudation points of Zha-xun mostly distribute on the cliffs of high mountains, which makes it difficult to evaluate its resource distribution and storage area. This paper was aimed at the exudation environment of Tibetan medicine Zha-xun in Sichuan province and 6 ecological environmental factors of the Zha-xun were determined via the field investigation. Combining with these 6 factors as well as the GIS data of Sichuan province, ArcGIS software was used to extract ideal environmental factors which are suitable for exudation of Zha-xun, including geology types, geomorphological types, altitude, slope, vegetation types, and mean annual temperature. The spatial overlay analyses on the extracted environmental factors were carried out to predict the distribution area of Zha-xun in Sichuan province. Afterwards, field investigation was conducted to verify the prediction. The prediction showed that the exudation spots of Zha-xun in Sichuan province mainly located in 29 counties including 12 in Aba Prefecture, 15 in Ganzi Prefecture, and Muli County and Dechang County in Liangshan Prefecture. The deposit areas of Zha-xun were located in the Triassic, Devonian and Silurian strata and were basically distributed in 9 basins, including Dingqu River, Yalong River, Xianshui River, Dadu River, Suomo River, Minjiang River and Baishui River, characterized by a fragmented patch-like distribution along the mountain ranges, and the exudation spots of Zha-xun were mainly scattered among the rain-free cliffs' concavities of river valleys at a certain altitude. The prediction was consistent with the field investigation results, which suggested that it is possible and feasible to predict distribution of Zha-xun resources based on GIS-analysis. The study may provide a scientific basis for comprehensive investigations into Zha-xun's distribution and formation mechanism, thus promoting rational development and utilization of Zha-xun resources.

The changing course of the Amazon River in the Neogene: center stage for Neotropical diversification

We review geological evidence on the origin of the modern transcontinental Amazon River, and the paleogeographic history of riverine connections among the principal sedimentary basins of northern South America through the Neogene. Data are reviewed from new geochronological datasets using radiogenic and stable isotopes, and from traditional geochronological methods, including sedimentology, structural mapping, sonic and seismic logging, and biostratigraphy. The modern Amazon River and the continental-scale Amazon drainage basin were assembled during the late Miocene and Pliocene, via some of the largest purported river capture events in Earth history. Andean sediments are first recorded in the Amazon Fan at about 10.1-9.4 Ma, with a large increase in sedimentation at about 4.5 Ma. The transcontinental Amazon River therefore formed over a period of about 4.9-5.6 million years, by means of several river capture events. The origins of the modern Amazon River are hypothesized to be linked with that of mega-wetland landscapes of tropical South America (e.g. várzeas, pantanals, seasonally flooded savannahs). Mega-wetlands have persisted over about 10% northern South America under different configurations for >15 million years. Although the paleogeographic reconstructions presented are simplistic and coarse-grained, they are offered to inspire the collection and analysis of new sedimentological and geochronological datasets.(AU)

Este trabalho é uma revisão das evidências geológicas sobre a origem do moderno rio Amazonas transcontinental, e a história paleogeográfica das conexões ribeirinhas entre as principais bacias sedimentares do norte da América do Sul durante o Neógeno. São revisados novos conjuntos de dados geocronológicos usando isótopos radiogênicos e estáveis, e de métodos geocronológicos tradicionais, incluindo sedimentologia, mapeamento estrutural, exploração sísmica e bioestratigrafia. O atual rio Amazonas e sua bacia continental se formaram durante o final do Mioceno e do Plioceno, através de alguns dos maiores eventos de captura de rio na história da Terra. Os sedimentos andinos são registrados pela primeira vez no leque fluvial do Amazonas por volta de 10,1-9,4 Ma, com um grande aumento na sedimentação a cerca de 4,5 Ma. O rio Amazonas transcontinental, portanto, se formou durante um período de cerca de 4,9 a 5,6 milhões de anos, por meio de vários eventos de captura de rios. Acredita-se que as origens do moderno rio Amazonas estejam ligadas às paisagens de inundação da América do Sul tropical (por exemplo, várzeas, pantanais, savanas sazonalmente inundadas). As áreas pantanosas persistiram em cerca de 10% do norte da América do Sul sob diferentes configurações por mais de 15 milhões de anos. Embora as reconstruções paleogeográficas apresentadas sejam simplistas, elas são oferecidas para inspirar a coleta e análise de novos conjuntos de dados sedimentológicos e geocronológicos.(AU)

James Parkinson and his essay on "shaking palsy", two hundred years later / James Parkinson y su ensayo sobre la "parálisis agitante", doscientos años después

ABSTRACT In 1817, British physician James Parkinson published a 66-page document entitled "Essay on the Shaking Palsy". This brief text became a classical and fundamental piece in the history of medicine and, in particular, of neurology. The authors of this article wish to pay tribute to this great pioneer of neurology, 200 years after the publication of his findings, which would, in turn, immortalize his name and give rise to the renaming on the entity in 1860 by Professor Jean Martin Charcot, father of neurology. It would be known, henceforth as Parkinson's disease.

RESUMEN En 1817 el médico británico James Parkinson publicó un documento de 66 páginas titulado "Ensayo sobre la parálisis agitante". Este breve texto es de una gran importancia en la historia de la medicina y en particular de la neurología. Los autores desean rendir homenaje a este gran pionero de la neurología al cumplir doscientos años la publicación que inmortalizaría su nombre y que dio origen a la primera descripción de la entidad que desde 1860, a propuesta del profesor Jean Martin Charcot, el padre de la neurología, se denomina Enfermedad de Parkinson.

Anatomical Achievement and Thought of Leonardo da Vinci / 체질인류학회지

Leonardo da Vinci is remembered as the greatest genius of the Renaissance. He left outstanding achievements as an artist, scientist and inventor, and contributes up to today's science. He ranks the best in a variety of fields, such as botany, mathematics, geology, astronomy, geometry and optics. It has well known that Leonardo is an artist, scientist, inventor and philosopher. And he was a great anatomist that dissected dead bodies and animals directly and left many anatomical drawings. He took an interest in anatomy from the point of view of the artist, which is why the human body structure and function to know the sakes were "ignorant of the anatomy should not be upset." Over time, he became interested in the structure and function of the body, even get the human body in a difficult environment; he dissected many the human bodies directly. His scientific inquiry and infatuation made him as an advanced pioneer for more than 100 years, and got enough level to surpass the artistry. Leonardo left about 1,800 anatomical figures of the muscular, skeletal, vascular, nervous and urogenital system, and they are also very scientific and high artistic achievements. The aim of this article is to take a look at Leonardo da Vinci's anatomical achievements and thoughts. In addition, the goal is to knowledge today's anatomists about Leonardo da Vinci's astonishing achievements as a great pioneer in anatomy.

Geomorfología, zonas de erosión y sedimentación costera de la Península de Burica, Costa Rica / Geomorphology, erosion and sedimentation in coastal zones of the Burica peninsula

Resumen Se efectuó una evaluación geomorfológica y de zonas de erosión y sedimentación del sector oeste de la Península, desde punta Banco hasta punta El Mangle, con el fin de determinar aspectos relevantes desde el punto de vista geológico. El estudio se llevo a cabo durante 9 días en enero del 2008, tiempo en el cual, se realizó el estudio geológico, geomorfológico y de zonas de erosión-sedimentación costera, presentándose en este trabajo solamente los resultados relevantes de los últimos dos aspectos. Geomorfológicamente, se reconocen una predominancia de morfologías de origen estructural, y en menor grado de origen marino, fluvial y denudacional. Se definieron cuatro zonas de erosión-sedimentación, zonas de erosión intensa, de erosión moderada a leve, de erosión y sedimentación y zonas de depositación. Los procesos geológicos más importantes son los deslizamientos, la erosión costera y la alta sismicidad del área, factores que deben ser tomados en cuenta para una adecuada planificación rural de la península

Abstract The present work describes a geomorpholopic evaluation of the Burica peninsula, during 9 days in January 2008. Coastal geomorphology, erosion and depositional zones were evaluated between punta Banco and punta El Mangle. The most important morphologies found were structural origin morphologies, represented by active tectonic deformation, produced by the Panamá Fracture Zone, and the subduction of the Cocos ridge. The structural origin morphologies identified were, structural-denudational zones which dominate the study area, homocline in the south of the peninsula and structural terraces, that are observed easily between punta El Mangle and La Peña, and in punta Banco. Other morphologies were identified, such as marine, fluvial and denudational morphologies. The marine-origin morphologies include the beach, subdivided in subareas, separated due to the waves dynamic, the cliffs, that dominate the area between La Peña river and punta Banco, and the shore platforms in the area between punta El Mangle and La Peña. The denudational morphology is represented by landslides, which area present mainly in the cliffs. In the other hand, the fluvial origin morphologies, include La Peña, Peñita, Caña Blanca and Coco mouths and the floodplain of La Peña river. Intense erosional, slight to moderate erosional, sedimentational, and erosion and sedimentational zones were identified, having a great importance the coastal erosion, especially observed in the central and south of the peninsula. Considering the results and the interaction of them, the main hazards found are landslides, coastal erosion and the high seismicity of the area, which should be taken into account and studied in detail for a proper planning of the rural development.

Bomb-cratered coral reefs in Puerto Rico, the untold story about a novel habitat: from reef destruction to community-based ecological rehabilitation / Los arrecifes de coral con craters-bomba en Puerto Rico, la historia no contada sobre un hábitat inusual: desde la destrucción de arrecifes hasta la rehabilitación ecológica basada en la comunidad

Ecological impacts of military bombing activities in Puerto Rico have often been described as minimal, with recurrent allegations of confounding effects by hurricanes, coral diseases and local anthropogenic stressors. Reef craters, though isolated, are associated with major colony fragmentation and framework pulverization, with a net permanent loss of reef bio-construction. In contrast, adjacent non-bombarded reef sections have significantly higher benthic spatial relief and biodiversity. We compared benthic communities on 35-50 year-old bomb-cratered coral reefs at Culebra and Vieques Islands, with adjacent non-impacted sites; 2) coral recruit density and fish community structure within and outside craters; and 3) early effects of a rehabilitation effort using low-tech Staghorn coral Acropora cervicornis farming. Reef craters ranged in size from approximately 50 to 400m² and were largely dominated by heavily fragmented, flattened benthos, with coral cover usually below 2% and dominance by non-reef building taxa (i.e., filamentous algal turfs, macroalgae). Benthic spatial heterogeneity was lower within craters which also resulted in a lowered functional value as fish nursery ground. Fish species richness, abundance and biomass, and coral recruit density were lower within craters. Low-tech, community-based approaches to culture, harvest and transplant A. cervicornis into formerly bombarded grounds have proved successful in increasing percent coral cover, benthic spatial heterogeneity, and helping rehabilitate nursery ground functions.

Los impactos ecológicos de las actividades militares de bombardeos en Puerto Rico se han descrito a menudo como mínimos, con recurrentes denuncias al confundir efectos por huracanes, enfermedades de corales y estresores antropogénicos locales. Los cráteres de arrecife, aunque aislados, están relacionados con una alta fragmentación de la colonia y pulverización del contorno, con una pérdida neta permanente de arrecife en bio-construcción. En contraste, secciones adyacentes de arrecife no bombardeado tienen mayor biodiversidad y mayor relieve espacial bentónico. Comparamos las comunidades bentónicas en cráteres-bomba de arrecifes de coral con 35-50 años de antigüedad en las islas de Vieques, Puerto Rico, en comparación con los sitios adyacentes no impactados; 2) la densidad de reclutamiento de coral y estructura de la comunidad de peces dentro y fuera de los cráteres; y 3) impactos preliminares de un esfuerzo de rehabilitación basado en la comunidad arrecifal usando tecnología simple con el cultivo del coral Staghorn Acropora cervicornis. Los cráteres de arrecife se distancian en tamaño de aproximadamente 50 a 400m² y fueron dominados ampliamente por fragmentos de bentos aplanado, con una cubierta de coral generalmente por debajo de 2% y el predominio de taxones no constructores de arrecifes (es decir, tapetes de algas filamentosas, macroalgas). La heterogeneidad espacial bentónica fue significativamente menor dentro de cráteres que también resultaron en un reducido valor funcional como tierra de vivero de peces. La riqueza de especies de peces, abundancia y biomasa y densidad coral recluta fueron significativamente menores dentro de cráteres. Tecnología simple, basada en los enfoques de cultivo de comunidad, la cosecha y transplante de A. cervicornis en terrenos anteriormente bombardeados han demostrado un éxito al aumentar el porcentaje de cobertura de coral, la heterogeneidad espacial bentónica y ayudando a rehabilitar funcionalmente la tierra para vivero.

Minério de ferro, geologia econômica e redes de experts entre Wisconsin e Minas Gerais, 1881-1914 / Iron ore, economic geology and networks of experts between Wisconsin and the state of Minas Gerais, 1881-1914

O presente artigo trata da “descoberta” do minério de ferro brasileiro a partir de duas perspectivas. A primeira analisa a crescente ênfase das geociências em sua aplicação prática e em sua globalidade desde a segunda metade do século XIX. Enquanto no Brasil a geologia econômica foi integrada passo a passo às instituições do Estado, no nível global ela viveu momento de triunfo com o 11 o Congresso Geológico Internacional, em 1910. A segunda trata de uma rede social específica com papel decisivo na corrida pelo minério de ferro brasileiro: experts transnacionais movimentandose entre as lógicas do mercado e as da academia. O artigo mostra a importância das negociações locais na incorporação do subsolo mineiro ao espaço global de mineração.

This article deals with the “discovery” of Brazilian iron ore from two perspectives. The first examines the increasing emphasis of the geosciences and their practical application and global reach since the second half of the nineteenth century. While in Brazil economic geology was integrated step by step into state institutions, at the global level it experienced its moment of triumph with the 11th International Geological Congress in 1910. The second deals with a specific social network with a decisive role in the race for Brazilian iron ore: with transnational experts juggling between the logic of the market and that of the academy. The article reveals the importance of local negotiations in the incorporation of the subsoil of Minas Gerais into the global space of mining.

Paul Deshayes (1796-1875) e a Comissao Geologica do Reino: uma colaboracao com o Estado portugues / Paul Deshayes (1796-1875) and the Geological Commission of the Kingdom: a collaboration with the Portuguese state

Carlos Ribeiro, um dos diretores da Comissão Geológica de Portugal, empreendeu em 1858 viagem por vários países da Europa, para adquirir bibliografia, equipamentos e coleções de comparação. Em Paris, conheceu o reputado conquiliologista Paul Deshayes, que lhe franqueou suas coleções pessoais do Terciário francês e o ajudou na classificação de fósseis portugueses. O trabalho conjunto revela-se na listagem de Ribeiro conservada no arquivo histórico do Laboratório Nacional de Energia e Geologia (Alfragide, Portugal), tendo aquelas classificações servido de base a uma monografia publicada por Pereira da Costa, parceiro de Ribeiro na Comissão Geológica, e à definição da estratigrafia dos depósitos terciários portugueses.

Carlos Ribeiro, one of the directors of the Geological Commission of Portugal, voyaged in 1858 to many countries of Europe to acquire publications, equipment and comparator collections. In Paris he met Paul Deshayes, a well-known conchologist, who gave him access to his personal collections of Tertiary deposits from France and helped him to classify Portuguese fossils. The outcome of the joint work can be seen in the Ribeiro List, which is preserved in the historic archives of the National Energy and Geology Laboratory (Alfragide, Portugal). These classifications served as a basis for a monograph published by Pereira da Costa, Ribeiro's colleague on the Geological Commission, and the definition of the stratigraphy of Portugal's Tertiary deposits.

A trajetória profissional de João Martins da Silva Coutinho relaciona-se à história do Museu Nacional (Rio de Janeiro), para cujas coleções, principalmente geológicas, ele contribuiu com informações científicas e remessa de material. No cenário científico brasileiro, participou de grandes comissões de caráter exploratório na segunda metade do século XIX, especialmente na Amazônia e no Nordeste. Coletou e enviou amostras para análise no Museu Nacional, estabelecendo profunda relação com a instituição e seus funcionários. Apresentam-se essas contribuições por meio da análise de documentos e da recuperação das coleções geológicas por ele remetidas e ainda presentes no acervo da instituição.

The career of João Martins da Silva Coutinho is linked to the history of the Museu Nacional in Rio de Janeiro to whose collections (especially geological) he contributed scientific information and material. On the Brazilian scientific stage, Silva Coutinho took part in major exploratory commissions in the latter half of the nineteenth century, mainly in the Amazon and in the Northeast. He collected and sent samples to the Museu Nacional for analysis, establishing deep ties with the institution and its staff. The article presents his contributions through an analysis of these documents and an examination of the geological collections that he sent to the institution and that remain part of its holdings.

Investigation of hydrogeological characteristics of Ardabil plain aquifer, northwest of Iran

In this paper, the hydrogeology of Ardabil plain has been investigated. The hydrogeologic properties of the study area were investigated based on geophysical, geological, water level and pumping test data, Also 65 wells were sampled and analyzed for hydrochemical investigation. Physical and chemical characteristics of groundwater such as temperature, EC, pH, TDS, Na[+], K[+], Mg[2+]+, C[2+]+ HCO[-3]-, SO[4][-2], Cl[-] and CO[3][2-] were determined. Hydrochemical studies indicated that geological units have the greatest effect on the groundwater quality in this plain. According to the results obtained, the Ardabil plain has two aquifers, which one of them is located on top of the other. The upper aquifer is multi-layer with varying thickness [20 to 40 m] across the plain and is extracted for different kind of water supply. The number of penetrating wells to the lower aquifer is very low and may not be extracted because of its poor water quality. General direction of groundwater flow is from other directions to the north-west of the plain. The estimated hydraulic parameters of transmissivity and specific yield varies spatially from 50 to 2200 [nr/day] and 0/021 to 0.14, respectively

Trace element geochemistry of Manilkara zapota [L.] P. royen, fruit from winder, balochistan, Pakistan in perspective of medical geology

An integrated study of rocks, soils and fruits of Manilkara zapota [L.] [Sapotaceae] of Winder area have been carried out to elaborate trace elements relationship between them. The igneous rocks of the study area have elevated amount of certain trace elements, upon weathering these elements are concentrated in the soil of the area. The trace elements concentration in the soil were found in the range of 0.8-197 for Fe, 1.23-140 for Mn, 0.03-16.7 for Zn, 0.07-9.8 for Cr, 0.05-2.0 for Co, 0.52-13.3 for Ni, 0.03-8.8 for Cu, 0.08-10.55 for Pb and 0.13-1.8microg/g for Cd. The distribution pattern of elements in the rocks and soils reflected genetic affiliation. Promising elements of edible part of the fruit were Fe [14.17], Mn [1.49], Cr [2.96], Ni [1.13], Co [0.92], Cu [1.70] and Zn [1.02microg/g]. The concentration of these elements in the fruits is above the optimum level of recommended dietary intake, probably due to this, disorder in the human health is suspected in the inhabitants of the area
