NEWS4CSP Project: New Coatings Approaches to Protect Metallic Materials From He...

ABSTRACT: The efficiency of Concentrated Solar Power technologies increases with the opera-tion temperature of the power block, which can be achieved using advanced power cycles operating at temperatures ≥650°C. Molten Salt (MS) based HTF have been facing critical chal-lenging issues of severe corrosion and lower specific heat capacity. This paper aims to present the NEWS4CSP project to the CSP scientific commu...

OHMi Estarreja: an ecosystem highly anthropized where contamination is the unif...

The Estarreja area (North of Portugal) has been subject to intense industrial pollution and host the second largest chemical industry complex in the country, which produced mainly ammonium sulphate, nitric acid and ammonium nitrate, but also synthetic resins. The CNRS’ Human–Environment International Observatory of Estarreja (OHMi Estarreja) aims to study the multiple effects of this industrial activity on the ...

Cost-efficiency improvement of bivalves shells preparation when tracing their g...

Developing methodologies employed to trace the geographic origin of seafood as accurate and fast as possible can help to speed-up the delivery of results to legal authorities, reduce associated costs and minimize environmental impacts (associated with the residues generated). The present study evaluated if trace element fingerprints (TEF) of a small homogenized subsample of Manila clams (Ruditapes philippinarum...

Spatial distribution of organic and inorganic contaminants in Ria de Aveiro Lag...

This paper presents baseline data of sediments characterization from Ria de Aveiro lagoon (Portugal). Twenty-two intertidal surface sediments were collected and analysed for their pseudo-total content of 25 major and trace elements and for their total content of PAHs (Sum16) and PCBs (Sum13). The fine fraction percentage and total organic carbon content were also determined. Ria de Aveiro Lagoon has been the ta...

Links between Cognitive Status and Trace Element Levels in Hair for an Environm...

In the present study, trace elements (TE) levels were evaluated in scalp hair along the continuum from healthy subjects (HS) to patients suffering from subjective memory concerns (SMC), and/or mild cognitive impairment (MCI), and those with already installed dementia (DEM) in order to: (i) assess the effects of environmental and lifestyle factors on TE concentrations and (ii) evaluate the analyzed elements as p...

Multivariate analysis for assessing sources, and potential risks of polycyclic ...

Urban soils quality may be severely affected by polycyclic aromatic hydrocarbons (PAHs) contamination, as is the case of Lisbon (Portugal). However, to conduct a risk assessment analysis in an urban area can be a very difficult task due to the patchy nature and heterogeneity of these soils. Thus, the present study aims to provide an example on how to perform the first tier of a risk assessment plan in the case ...

THE ENVIRONMENTAL IMPACT OF USING COPPER SULPHATE TO AVOID GRAPEVINE POWDERY MI...

Copper-based fungicides have been used in vineyards throughout the world, for many decades to protect against downy mildew. However, their use results in an accumulation of Cu in surface soils which can potentially impact on the biological health of the soil and could be transported and stored in the sediments deposited close to valley bottoms. In Douro region, northern of Portugal, vineyards are located on ste...

GRAPEVINE CULTIVATION AND THE GEOCHEMISTRY OF ZINC: IMPACT ON THE ENVIRONMENTAL...

This study presents preliminary results of a research project that aims assessing the environmental impact of intensive grapevine cultivation in the Alto Douro wine region, a World Heritage Site. A total of 50 soil samples were collected from three nearby vineyards of different ages. Surface drainage of these vineyards discharges into an important water reservoir, the Varosa Dam. The dam collects water from two...
