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...

Estudos de especiação de arsénio em arroz

The EuroFIR Food Platform: Further integration, refinement and exploitation for...

Background and objectives Previous investigations have identified that analytical methodology is a key factor in data quality and specific criteria at the component level are needed for comparison of analytical data from different sources, especially by food composition data compilers that are often not experienced analysts. The aim of this work is to describe how the EuroFIR guidelines for assessment of method...

Arsenic speciation in rice and fish using HPLC-ICP-MS

Chemical speciation in foodstuffs is of uttermost importance since it is nowadays recognized that both toxicity and bioavailability of an element depend on the chemical form in which the element is present. Regarding arsenic, inorganic species are classified as carcinogenic while organic arsenic, such as arsenobetaine (AsB) or arsenocholine (AsC), is considered less toxic or even non-toxic. Coupling a High Perf...

Arsénio e crómio: técnicas analíticas para avaliar o seu impacto na saúde das p...

A ingestão de alimentos representa a principal fonte de exposição humana ao arsénio, sendo que a sua acumulação no organismo causa doenças a médio e longo prazo. No entanto a toxicidade dos elementos não depende apenas do seu teor total mas principalmente da espécie química em que estes se encontram presentes nos alimentos. No caso particular do arsénio, as espécies inorgânicas são mais tóxicas que as orgânicas...

Proximate and Mineral profile of Quinoa (Chenopodium quinoa), and kiwicha (Amar...

Quinoa (Chenopodium quinoa), and kiwicha (Amaranthus caudatus) are pseudo-cereals largely consumed in North of Argentina. They gained special attention by scientific community in part due to high nutritional value. Therefore the nutrient analysis with the purpose to be included in Argentinean Food Composition Databank is urgent. In this work proximal and mineral profile of Quinoa consumed in the North of Argent...
