Assessment of surface water in two Amazonian rivers impacted by industrial wastewater, Barcarena City, Pará State (Brazil)

No ano de 2007, águas superficiais foram coletadas a partir de 21 pontos de amostragem na cidade de Barcarena, Região Norte, Brasil: um ponto de amostragem localizado em um pequeno córrego que recebe descarga de resíduos a partir da indústria de beneficiamento do caulim e deságua no Rio Curuperê, três pontos de amostragens localizados próximos de fontes que emergem na margem esquerda e deságuam no Rio Curuperê, nove pontos de amostragem no Rio Curuperê, que deságua no Rio Dendê, e oito no Rio Dendê, afluente da margem esquerda do Rio Pará. Para todas as amostras de água foram quantificadas 14 variáveis físico-químicas e níveis de 12 metais. Os resultados nos pontos próximos das fontes do Rio Curuperê apresentaram perfil físico-químico e níveis de metais típicos para águas superficiais e esses valores foram utilizados como referência para comparar e identificar possíveis alterações nas características químicas para os demais pontos de amostragem. Quando os resultados das fontes do rio Curuperê foram comparados com os resultados do ponto próximo a descarga de resíduos industriais foram observadas fortes alterações nos valores de 6 variáveis físico-químicas (pH, condutividade elétrica (EC), total de sólidos suspensos (TDS), nitrogênio amoniacal (N-NH4), sulfato (SO4) e salinidade) e aumento em magnitude dos níveis de quatro metais (Al, Fe, Mn e Zn), caracterizando que esses resíduos eram descarregados no ambiente sem tratamentos adequados. Os resultados nos demais pontos de amostragem demonstraram que estas condições anômalas também foram encontradas ao longo dos Rios Curuperê e Dendê, principalmente durante a maré baixa. A partir desta caracterização química das águas foram identificadas condições prejudiciais aos ecossistemas aquáticos e potencial risco à saúde da população local que usa os rios para consumo, recreação e transporte.

Influence of sample matrix on the alkaline extraction of Cr(VI) in soils and industrial materials

An accurate and efficient determination of the highly toxic Cr(VI) in solid materials is important to determine the total Cr(VI) inventory of contaminated sites and the Cr(VI) release potential from such sites into the environment. Most commonly, total Cr(VI) is extracted from solid materials following a hot alkaline extraction procedure (US EPA method 3060A) where a complete release of water-extractable and sparingly soluble Cr(VI) phase is achieved. This work presents an evaluation of matrix effects that may occur during the hot alkaline extraction and in the determination of the total Cr(VI) inventory of variably composed contaminated soils and industrial materials (cement, fly ash) and is compared to water-extractable Cr(VI) results. Method validation including multiple extractions and matrix spiking along with chemical and mineralogical characterization showed satisfying results for total Cr(VI) contents for most of the tested materials. However, unreliable results were obtained by applying method 3060A to anoxic soils due to the degradation of organic material and/or reactions with Fe2+-bearing mineral phases. In addition, in certain samples discrepant spike recoveries have to be also attributed to sample heterogeneity. Separation of possible extracted Cr(III) by applying cation-exchange cartridges prior to solution analysis further shows that under the hot alkaline extraction conditions only Cr(VI) is present in solution in measurable amounts, whereas Cr(III) gets precipitated as amorphous Cr(OH)3(am). It is concluded that prior to routine application of method 3060A to a new material type, spiking tests are recommended for the identification of matrix effects. In addition, the mass of extracted solid material should to be well adjusted to the heterogeneity of the Cr(VI) distribution in the material in question.

Monitoring of industrial exposure for chloracne

This study (1) established comedogenicity dose response curves for the pure compounds of 3,3$\sp\prime$,4,4$\sp\prime$-tetrachloroazobenzene (TCAB) and 3,3$\sp\prime$,4,4$\sp\prime$-tetrachloroazoxybenzene (TCAOB) individually and as a couple-compound using a rabbit ear model; (2) used a rabbit ear model to establish comedogenicity potential for TCAB and TCAOB as they existed in a given industrial herbicide manufacture process; (3) evaluated actual environmental contamination in a herbicide industrial setting by air monitoring and wipe sampling; (4) biologically monitored potentially exposed workers for alterations in follicular orifice size as an index of actual exposure to chloracnegenic compounds; and (5) biologically monitored potentially exposed workers for changes in weight, cholesterol, triglycerides and blood sugar.^ A silastic monomer mold (an objective measure) was used to measure change in follicular orifice size over time. This required taking impressions of (1) skin of the forehead and right and left malar crescents of workers and (2) the skin of the external ear of the rabbit. Molds were stained using a solution of hematoxylin and digitized using a Nikon UFX microscope (magnification 300 X), a drawing tube and a digitizing tablet attached to an IBM Personal Computer. Comedogenicity assays were used to establish dose-response curves for TCAB, TCAOB and the couple-compound TCAB + TCAOB.^ No evidence of chloracne or toxicity was observed in any of the workers. Nor, was there a statistically significant increase in size of follicular orifice means measured over time. This was attributed to extensive personal and environmental hygiene programs along with teaching the workers about chloracne, its cause and its prevention. These programs may have been the greatest factor in preventing the development of chloracne in this group of workers. Monitoring of the plant environment showed relatively high concentrations of the couple-compound (TCAB + TCAOB). Comedogenicity assays showed a linear dose-response relationship over time for TCAB, TCAOB and the couple-compound. An antagonistic action was found for the TCAB/TCAOB of the couple-compound; such action may provide some protection to workers in this type of setting. It is speculated that the observed antagonistic action may be due to the difference in binding affinities of TCAB/TCAOB for receptor sites. ^

Vanguardias figurativas y arquitectura industrial en el período entreguerras (1918-1939)

Una de las características más interesantes que define a las Vanguardias Figurativas de comienzos del siglo XX es su fascinación por el mundo industrial como punto de ruptura con el pasado y fe en el progreso: la velocidad, la industrialización, las posibilidades de la electricidad, el maquinismo?, son elementos comunes a movimientos como el Futurismo o el Constructivismo, donde Arte, Arquitectura e Ingeniería se dan la mano en obras integradoras a medio camino entre lo utópico y lo visionario. De especial interés resulta el estudio de las obras industriales diseñadas y construidas en el período denominado de "entreguerras" (entre la Primera y la Segunda Guerra Mundial, 1918-1939), entre las que podríamos destacar los dibujos de Sant¿Elia, la presa de Klingenberg, de Poelzig y, sobre todo, los proyectos de Casto Fernández-Shaw. Este singular arquitecto ideó, entre 1918 y 1919, lo que él llamaría un "Monumento al Triunfo de la Civilización, a las Grandes Conquistas de la Idea, a las Victorias del Hombre sobre la Naturaleza, a la Paz Universal". Se trata en realidad de una gran presa (construcción que Casto asocia con el avance de la tecnología y el conocimiento humano), de aires egipcios con dos potentísimos pilonos que arrojan sendos haces de luz hacia el cielo. Aunque el proyecto nunca se llevó a cabo, estas ideas futuristas y utópicas nunca abandonarían a Casto y supondrían una notable influencia en el resto de su obra. En esta comunicación analizaremos estos interesantes ejemplos de arquitectura industrial, relacionándolos no sólo entre sí y con el resto de obras de sus autores, sino también con otros edificios construidos posteriormente pero profundamente influidos por estas corrientes vanguardistas (como la presa de Grandas de Salime, 1948-1954, de Joaquín Vaquero Palacios).

O AGENDAMENTO DE TELEJORNAIS BRASILEIROS EM SITES NOTICIOSOS DE CONTEÚDO COLABORATIVO

The thesis investigates if with the free news production, people who post information on collaborative content sites, known as interacting, tend to reproduce information that was scheduled for Tv news. This study is a comparison of the collaborative content vehicles Vc reporter, Vc no G1 and Eu reporter with TV news SBT Brasil, Jornal Nacional, Jornal da Record and Jornal da Band. We sought to determine whether those newscasts guide the collaborative platforms. The hypothesis assumes that Brazilian TV news have been building over time a credible relationship with the viewer, so it is possible to think that the interacting use the same criteria for selecting the broadcasts and reproduce similar information in collaborative content sites. The method used was content analysis, based on the study of Laurence Bardin and the type of research used was quantitative. This research concluded that, within a small portion of the universe surveyed, there are schedules of television news across the collaborative content.

Practice report: the role of environmental factors in industrial site selection activities: a case of limestone quarry expansion in Barbados, West Indies

Site selection is a key activity for quarry expansion to support cement production, and is governed by factors such as resource availability, logistics, costs, and socio-environmental factors. Adequate consideration of all factors facilitates both industrial productivity and sustainable economic growth. This study illustrates the site selection process that was undertaken for the expansion of limestone quarry operations to support cement production in Barbados. First, alternate sites with adequate resources to support a 25-year development horizon were identified. Second, socio-environmental conditions were described and potential impacts identified. Third, a comparative matrix was constructed to evaluate relative site characteristics with respect to physical, ecological, socio-cultural and economic factors. The study shows that environmental factors were essential to the final site recommendation.
