Cumplicidades com o território expectante : projetar o Vale de Massarelos

Dissertação de mestrado em Arquitectura (área de especialização em Cidade e Território) ; A presente tese reflecte e constrói um modo de actuar sobre os espaços inativos em contexto urbano, propondo sistemas de espaço público que corrijam problemas e explorem oportunidades. Desenvolve-se a temática com o Vale de Massarelos como objecto de estudo, fundando uma interpretação e crítica de onde resultam estratégia...

HERA - Environmental Risk Assessment of a contaminated estuarine environment: a...

Sado River estuary is located in the west coast of Portugal. Previous environmental studies identified industrial contamination, non-point anthropogenic sources and contamination coming from the river, all promoting accumulation of polluted sediments with known impacts on the ecological system. Surrounding human populations have intense economic fishery activities. Together with agriculture, estuary fishing pro...

Genotoxicity and oxidative stress induced by sediments from the Sado Estuary an...

The Sado Estuary is affected by various sources of pollution, such heavy-industry, urbanism, mining, agriculture and maritime traffic and sizable amounts of organic and inorganic contaminants were identified in the sediments. These compounds can be accumulated in the edible parts of estuarine species and agricultural products, thus entering the human food chain and posing a public health problem. This study had...

Cytotoxic and genotoxic potential of sediments from the Portuguese Mira-River E...

The Mira-River Estuary (SW Portugal) although being a protected natural area has been affected by urban pollution from the village of Vila Nova de Milfontes (VNMF) and by contaminants from farming and aquaculture activities. The present study is part of a broader project comprising the evaluation of environmental and human health risks from potentially contaminated estuaries and aims to assess the cytotoxic and...

Avaliação do risco ambiental e para a saúde pública de um ambiente estuarino co...

O estuário do rio Sado é um ecossistema de elevado valor ecológico e económico. Apesar de ter vindo a ser afetado ao longo dos anos por várias fontes de poluição de origem urbana, industrial e agrícola, continua ainda a ser, para a população local, um local privilegiado para atividades piscícolas e agrícolas. Contudo, existe uma preocupação relacionada com a potencial bioacumulação de contaminantes nas partes e...

DNA and Chromosome Damaging Effects in Mice Exposed to an Estuary Sediment Extract

Previous studies have shown that an extract of a sediment sample collected in a fishing area of Sado Estuary, impacted by the urban and industrial pollution from the city of Setúbal, was able to induce cytotoxicity and genotoxicity in a human cell line (HepG2) and in local aquatic species, probably due to the presence of PAHs and metals. However, the assessment of the potential hazard of those contaminants to h...

Evaluation of Genotoxicity of Sediments from the Sado-River Estuary Using Solve...

Located in the western coast of Portugal, our case study, the river Sado Estuary, is affected by various sources of pollution, such as heavy-industry, urbanism, mining, agriculture and maritime traffic. Recent studies showed that sediment samples were contaminated with a mixture of different groups of contaminants related to the different anthropogenic pressures along the estuary. The present study aims to asse...

Can Estuary Sediment Contaminants Interfere with the DNA Repair Capacity of HEP...

Estuarine sediments tend to act as reservoirs of pollutants, many of which are acknowledged genotoxicants and potential carcinogens for humans. In addition, many of these environmental contaminants, particularly metals, have the potential to interfere with DNA repair mechanisms. Taking an impacted estuary as a case study (the Sado, SW Portugal), previous studies showed that human hepatoma cells (HepG2) exposed ...

Efeito da época e intensidade de monda nas castas Aragonês e Alicante Bouschet

Mestrado em Engenharia Agronómica - Instituto Superior de Agronomia ; The quality of the grapes is changeable and through this study we pretend to analyze the effect of intensity and season of cluster’s thinning (M0 – control, M1 – thinning, leaving one cluster/ talon in buckshot berry season, M2 - thinning, leaving one cluster/talon in verasion season, M3 - thinning, leaving one cluster/stalk in buckshot berr...
