Influence of different land uses on groundwater quality in southern Portugal

In Alentejo region, southern Portugal, differences in groundwater samples from six groundwater bodies covered with different land uses were analysed based on the monitoring plan of the Alqueva multi-purpose project, created in the sequence of the construction of the Alqueva Dam on the Guadiana River, in South Portugal. For most of the groundwater bodies there is a statistical significant difference between magnesium, sulphate, chloride, and phosphate. All of these ions are strongly correlated with land use management. Groundwater, where land is covered by olive groves, has high levels of electric conductivity, calcium, potassium, sulphate, and phosphate. Dry land crops are correlated with calcium, magnesium, chloride and consequently, electric conductivity, phosphates and sulphate. Vineyards are strongly correlated with high sulphate and phosphate levels. This study clearly shows that different land uses within a certain groundwater body influence the water quality in a different way. Therefore, an appropriate soil management should be adjusted to each situation, taking into account the aquifer matrix and the overlying soil.

Planos nacionais de controlo dos géneros alimentícios

Este relatório descreve as atividades desenvolvidas durante o estágio curricular do curso de Mestrado Integrado em Medicina Veterinária no âmbito da inspeção sanitária e saúde pública, realizado tanto nos PIF de Lisboa, como na Divisão de Riscos Alimentares (DRA) da Autoridade de Segurança Alimentar e Económica (ASAE). Existe uma grande variedade de produtos e animais que chegam diariamente à União Europeia provenientes de diferentes países terceiros, como por exemplo a China, África do Sul, Brasil, Índia, Canadá e Senegal. Durante o período de estágio a categoria dos produtos mais inspecionada nos PIF foi o pescado representando 57,5% da totalidade das remessas inspecionadas nos portos de Lisboa e 98% no aeroporto. No âmbito do plano de fiscalização da ASAE em 2015, a aluna analisou 365 amostras de géneros alimentícios e constatou-se que o número de amostras não conformes foi 254. O grupo das bebidas alcoólicas destacou-se com 159 amostras não conformes; Abstract: National Control Plans of Food This essay describes the activities developed throughout the curricular internship of the Integrated Master of Veterinary Medicine within sanitary inspection and public health, both at border control of Lisbon as well as in the Divisão de Riscos Alimentares (DRA) of the Autoridade de Segurança Alimentar e Económica (ASAE). There is a wide variety of products and animals that arrive daily to the European Union from third countries, such as China, South Africa, Brazil, India, Canada and Senegal. During the internship the largest category of inspected food was fish representing 57.5% of the inspected remittances in the port of Lisbon and 98% in the airport. As part of the fiscalization plan of ASAE in 2015 the student analysed 365 food samples and it was found that the number of samples non-conforming was 254. The ardent spirits was the category that stood out with 159 non-conforming samples (63%).
