Responsabilidade ambiental no perímetro industrial da Monteiro, Ribas – Indústrias, S.A.

A presente dissertação tem como intuito aplicar o regime de Responsabilidade Ambiental no perímetro industrial da Monteiro, Ribas – Indústrias, S.A.. Para tal, averiguou-se que na ordem jurídica nacional, o regime de Responsabilidade Ambiental (RA) encontra-se consagrada na legislação nacional pelo Decreto-Lei nº 147/2008 de 29 de Julho (Diploma RA),e respetivas alterações, aplicando-se a danos ambientais ou ameaças iminentes de danos ambientais causados aos recursos naturais nomeadamente “espécies e habitats naturais protegidos”, “água” e “solo”. Também se verificou que este regime introduz obrigações específicas para os operadores abrangidos, designadamente é da responsabilidade do operador aplicar as medidas de prevenção e reparação dos danos, devendo ser reportados os acontecimentos à autoridade competente, Agência Portuguesa do Ambiente. Para cumprimento do requisito da garantia financeira e sendo a Monteiro, Ribas – Indústrias, S.A. enumerada no Anexo III do Decreto-Lei nº 147/2008 de 29 de Julho, optou-se pela constituição de um fundo próprio no valor de 50.000,00€. Com recurso à metodologia proposta pela Norma Espanhola UNE 150008:2008 - Análise e avaliação do Risco Ambiental, procedeu-se à formulação de vários cenários e quantificação de riscos para a Monteiro, Ribas – Indústrias, S.A. tendo-se apurado que os riscos estavam avaliados como baixo ou moderado. Por fim, conclui-se que em Portugal, embora exista um Decreto-Lei sobre Responsabilidade Ambiental, este tema ainda não está suficientemente desenvolvido pois não permite proceder a análise e avaliação do risco ambiental, tendo sido tomado assim como referência a metodologia aplicada na Norma Espanhola UNE 150008:2008.

Antineoplastic drugs contamination of workplace surfaces in two Portuguese hospitals

Despite the classification as known or suspected human carcinogens, by the International Agency for Research on Cancer, the antineoplastic drugs are extensively used in cancer treatment due to their specificity and efficacy. As human carcinogens, these drugs represent a serious threat to the healthcare workers involved in their preparation and administration. This work aims to contribute to better characterize the occupational exposure of healthcare professionals to antineoplastic drugs, by assessing workplace surfaces contamination of pharmacy and administration units of two Portuguese hospitals. Surface contamination was assessed by the determination of cyclophosphamide, 5-fluorouracil, and paclitaxel. These three drugs were used as surrogate markers for surfaces contamination by cytotoxic drugs. Wipe samples were taken and analyzed by HPLCDAD. From the total of 327 analyzed samples, in 121 (37%) was possible to detect and quantify at least one drug. Additionally, 28 samples (8.6 %) indicate contamination by more than one antineoplastic drug, mainly in the administration unit, in both hospitals. Considering the findings in both hospitals, specific measures should be taken, particularly those related with the promotion of good practices and safety procedures and also routine monitoring of surfaces contamination in order to guarantee the appliance of safety measures.

Ecotoxicological aspects related to the presence of pharmaceuticals in the aquatic environment

Pharmaceuticals are biologically active and persistent substances which have been recognized as a continuing threat to environmental stability. Chronic ecotoxicity data as well as information on the current distribution levels in different environmental compartments continue to be sparse and are focused on those therapeutic classes that are more frequently prescribed and consumed. Nevertheless, they indicate the negative impact that these chemical contaminants may have on living organisms, ecosystems and ultimately, public health. This article reviews the different contamination sources as well as fate and both acute and chronic effects on non-target organisms. An extensive review of existing data in the form of tables, encompassing many therapeutic classes is presented.

Environmental mycology in public health: fungi and mycotoxins risk assessment and management

Fungi are essential to the survival of our global ecology, but they might pose a significant threat to the health of occupants when they grow in our buildings. The exposure to fungi in homes is a significant risk factor for a number of respiratory symptoms. Well-known illnesses caused by fungi include allergy and hypersensitivity pneumonitis. Environmental monitoring for fungi and their disease agents are important aspects of exposure assessment, but few guidelines exist for interpreting their health impacts. This book answers the questions: How does one detect and measure the presence of indoor fungi? What is an acceptable level of indoor fungi? How do we relate this information to human health problems?

Caracterização dos consumos energéticos e estudo do potencial de melhoria da eficiência energética em edifícios de escritórios

A forte preocupação ambiental, nomeadamente a emissão de Gases com Efeito de Estufa (GEE), aliada à constante ameaça do esgotamento dos combustíveis de origem fóssil, leva à necessidade de consumir energia de forma mais eficiente. Neste sentido, surge a promoção da eficiência energética nos diversos sectores consumidores de energia em todo o Mundo. Sabendo que passamos mais de 80% do nosso tempo dentro de edifícios, e que cerca de 40% da energia mundial é consumida nos mesmos [ADENE], é importante operar no sentido de promover a utilização racional de energia e incentivar ao consumo eficiente da mesma nos edifícios. Apesar do esforço que tem sido realizado a nível nacional, no sentido de melhorar a eficiência energética em edifícios de serviços, através da implementação de legislação diversa e de vários programas de incentivo, existem ainda várias lacunas a serem colmatadas e muito trabalho a fazer nesse sentido. Por tudo isto, e principalmente por ter constantemente em mente premissas como “a energia mais barata é aquela que não se consome” ou “não podemos gerir aquilo que não medimos”, surgiu a ideia de realizar esta dissertação, onde inicialmente através de dados provenientes de telecontagem se desenvolve uma tentativa de padronização/tipificação do consumo eléctrico em seis edifícios de escritórios, identificando-se assim algumas situações anómalas em diversos diagramas de carga construídos. Relaciona-se também o consumo eléctrico dos seis edifícios com algumas variáveis exógenas, de modo a perceber a influência das mesmas no consumo eléctrico de cada edifício. Numa vertente mais prática, foram identificadas e quantificadas potenciais medidas de melhoria, comportamentais e técnicas, num dos edifícios em estudo, de modo a poder contribuir para a redução do consumo energético do mesmo. Espera-se que este trabalho, possa eventualmente constituir uma ajuda na caracterização de consumos e detecção de medidas de melhoria em edifícios de escritórios, alcançando a eficiência energética neste tipo de instalações e facilitando assim o trabalho de vários profissionais do sector. Pretende-se igualmente demonstrar a importância da eficiência energética na gestão do uso da energia eléctrica em edifícios, e efectuar um paralelo entre a energia economizada por meio da implementação de medidas/acções de uso racional e eficiente, com a redução da queima de combustíveis fosseis na geração de energia eléctrica e a sua consequente redução nas emissões de dióxido de carbono (CO2), com o objectivo final de melhorar a qualidade de vida no nosso planeta.

Plasmodium falciparum drug resistance in Angola

Facing chloroquine drug resistance, Angola promptly adopted artemisinin-based combination therapy as the first-line to treat malaria. Currently, the country aims to consolidate malaria control, while preparing for the elimination of the disease, along with others African countries in the region. However, the remarkable capacity of Plasmodium to develop drug resistance represents an alarming threat for those achievements. Herein, the available, but relatively scarce and dispersed, information on malaria drug resistance in Angola, is reviewed and discussed. The review aims to inform but also to encourage future research studies that monitor and update the information on anti-malarial drug efficacy and prevalence of molecular markers of drug resistance, key fields in the context and objectives of elimination.

Early physiological and biochemical responses of rice seedlings to low concentration of microcystin-LR

Microcystin-leucine and arginine (microcystin- LR) is a cyanotoxin produced by cyanobacteria like Microcystis aeruginosa, and it’s considered a threat to water quality, agriculture, and human health. Rice (Oryzasativa) is a plant of great importance in human food consumption and economy, with extensive use around the world. It is therefore important to assess the possible effects of using water contaminated with microcystin-LR to irrigate rice crops, in order to ensure a safe, high quality product to consumers. In this study, 12 and 20-day-old plants were exposed during 2 or 7 days to a M. aeruginosa extract containing environmentally relevant microcystin-LR concentrations, 0.26–78 lg/L. Fresh and dry weight of roots and leaves, chlorophyll fluorescence, glutathione S-transferase and glutathione peroxidase activities, and protein identification by mass spectrometry through two-dimensional gel electrophoresis from root and leaf tissues, were evaluated in order to gauge the plant’s physiological condition and biochemical response after toxin exposure. Results obtained from plant biomass, chlorophyll fluorescence, and enzyme activity assays showed no significant differences between control and treatment groups. How- ever, proteomics data indicates that plants respond to M. aeruginosa extract containing environmentally relevant microcystin-LR concentrations by changing their metabolism, responding differently to different toxin concentrations. Biological processes most affected were related to protein folding and stress response, protein biosynthesis, cell signalling and gene expression regulation, and energy and carbohydrate metabolism which may denote a toxic effect induced by M. aeruginosa extract and microcystin- LR. Theimplications of the metabolic alterations in plant physiology and growth require further elucidation.

First isolation of dengue 3 in Brazil from an imported case

The authors report the isolation of dengue 3 virus for the first time in Brazil. The patient, resident in Limeira-SP, traveled to Nicaragua on May 16th, 1998, where he stayed for two months. Starting on August 14th he had fever, headache, myalgia, arthralgia, retro-orbital pain and diarrhea. He returned to Brazil on August 16th and was hospitalized in the next day. The patient had full recovery and was discharged on August 20th. The virus was isolated in C6/36 cell culture inoculated with serum collected on the 6th day after the onset of the symptoms. The serotype 3 was identified by indirect immunofluorescence assays performed with type-specific monoclonal antibodies. This serotype was further confirmed by polymerase chain reaction analysis. The introduction of a new dengue serotype in a susceptible population is a real threat for the occurrence of severe forms of the disease. The isolation and identification of dengue virus are important in order to monitoring the serotypes circulating in Brazil and to take the measures necessary to prevent and control an epidemic.

Strategic Drivers for Implementing Sustainability Programs in Portuguese Organizations– Let’s Listen to Aristotle: From Triple to Quadruple Bottom Line

This article describes a study that investigated the main strategic drivers that influence the implementation of sustainability/social responsibility programs. An online survey was administered to managers of Portuguese organizations with certified management systems. The findings suggest that the implementation of such programs is mainly correlated to: 1.) the approach to understanding and working toward the satisfaction of the community’s needs (in the broad sense of social responsibility); 2.) how systematically sustainability within the organization is identified and managed (e.g., pollution prevention, improved environmental performance, and compliance with the applicable environmental laws); and 3.) the degree to which the organization tries to understand the needs of the employees and works toward satisfying them. In addition to the survey, five interviews with top managers of the surveyed organizations provided some useful insights. There was no consensus on the meaning of sustainability and social responsibility: some described it as an instrumental approach for obtaining better organizational results, while others regarded it as the right thing to do (i.e., it is values driven). In all cases, however, the managers supported a kind of umbrella construct under which different size corporations use different models (for example, the Dow Jones Sustainability Index (DJSI), Global Reporting Initiative (GRI), ISO 14001 environmental management systems), although some managers reported that they simply do not know what to do. All of those surveyed agreed that the lack of a systematic approach could represent a major threat to their organization, making them willing to pay more attention and take more action on the issue of sustainability. An additional suggestion made by managers was to change from a triple bottom line (economic dimension, environmental dimension, social equity dimension) to a quadruple bottom line by adding another dimension: personal and family happiness. This fourth dimension was recognized by the Greek philosopher/thinker Aristotle (384-322 BCE) who thought of happiness as the highest good (virtue) and ultimate goal and purpose of life, achieved through living well, in harmony. Such harmony suggests a balance and a lack of excess—in other words a sustainable existence.
