HERA - Environmental Risk Assessment of a contaminated estuarine environment: a...
Martinho, Ana Paula; Rodrigo, Ana; Vicente, Ana; Machado, Ausenda; Dias, Carlos Matias; Guiomar, Carla Sofia; Gonçalves, Cátia; Paixão, EleonoraSado 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...
Pinto, Miguel; Sacadura, Joana; Louro, Henriqueta; Costa, Pedro Manuel; Costa, Maria Helena; Caeiro, Sandra; Lavinha, João; Silva, Maria JoãoThe 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...
DNA and Chromosome Damaging Effects in Mice Exposed to an Estuary Sediment Extract
Pinto, Miguel; Sacadura, Joana; Louro, Henriqueta; Costa, Pedro Manuel; Lavinha, João; Silva, Maria JoãoPrevious 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...
Vicente, Ana Margarida; Sacadura, Joana; Pinto, Miguel; Louro, Henriqueta; Costa, Pedro Manuel; Lavinha, João; Caeiro, Sandra; Silva, Maria JoãoLocated 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...
