Lay rationalities of climate change

In this special issue we were also interested in revealing the level of concepts and the level of social action, trying to contribute to the answer of questions like: How local populations explain, interpret and deal with climate change? What are the individual and collective actions in response to climate change? How do populations deal with Climate Change mitigation (risk perception and risk-mitigating)? What...

Sea warming affects bream (Sparus aurata) tissues and stress proteins (HSP70)

The aim of the present study is to assess the stress response of a marine fish, sea bream (Sparus aurata) exposed to increasing water temperature and different water acidity (alone or in combination). Here we present preliminary data on temperature effects on S. aurata at a cellular and molecular level. In addition, tissue samples from muscle, livers, gills and intestine are examined to evaluate any alterations...

Assessment of sediment contamination in an impacted estuary: differential effec...

Conferência realizada em Lisboa, de 6-9 November de 2013 ; Estuarine pollution is reflected in the concentration of toxicants in sediments, depending on their geochemical properties, since sediments trap substances from the water column, either dissolved or bound to suspended matter. However, determining risk of sediment contaminants to biota has many constraints. For such reason, integrative approaches are ke...

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...
