This work aimed to evaluate the potential of Fe2O3 nanoparticles (nano-Fe2O3) to alleviate potentially toxic elements (PTEs) - induced stress in barley plants (Hordeum vulgare L.), focusing on bioaccumulation patterns and on plant growth and redox homeostasis. To achieve this goal, plants grew in two agricultural soils, contaminated by different levels of PTEs, collected from an industrial area, p...
Areas such as Douro Demarcated Region (Portugal), where vineyards are frequently located on steep slopes of narrow valleys, can be particularly sensitive to runoff and erosion processes. These particular conditions are expected to enhance the transport of pollutants, acting as a potential source of contamination to freshwater systems. The intense vine cultivation in this region includes decades o...
Los suelos lateriticos se han utilizado ampliamente en la construccion de revestimientos de basureros para residuos municipales e industriales. Por otro lado, hay poca practica en el uso de suelos residuales fuertemente meteorizados para esta finalidad. El uso de suelo local para la construccion de revestimientos para impermeabilizar y retener contaminantes representa una alternativa para controla...
Mining has a very economic importance worldwide and remains an essential part of the economy in different countries (Nansai et al. in Environ Sci Technol 49(4):2022–2031, 2015; Galas and Galas in Resour Policy 49:204–212, 2016).
The industrial chemical complex of Estarreja (ICCE), lat 40°45′N, long 8°35′ W, operates since the 1950’s. Several plants have disposed locally residues and effluents, discharging them into natural water lines, opening channels, surface and buried deposits, in an area that houses an important aquifer system. These residues range from heavy metals to organic compounds. The area around the ICCE has...
The Bracal –Malhada mining region, 30km NE of Aveiro included several silver-lead mines that operated until mid 20th century. Mineralization consists on sulphides (galena, sphalerite, pyrite) in quartz veins occurring in the complex Porto-Tomar shear zone, Fig. 1 . Veins develop in a 10km wide area, show different orientations, are found in granites, schists and even quartzite, and can pass throu...
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 (Ruditape...
Soil is a major reservoir for Potential Toxic Elements (PTEs). These PTEs can occur in various forms in soil and different bonding forces keep them bound to soil particles. The high concentrations, form and availability of PTEs in environment, can compromise the soil ecosystem and the growth of plants. At the end of the chain PTEs may entering in human body by direct (inhalation or ingestion of s...
