Waste electric and electronic equipment (WEEE) represents a potential secondary source of valuable materials, whose recovery is growing business activity worldwide. In low-income countries, recycling carried out under poorly controlled conditions resulting in severe environmental pollution. High concentrations both metallic organic pollutants have been confirmed air, soil, water, sediments countries with informal areas. The release these contaminants into the environment presents risk to...
Instrumental neutron activation analysis (INAA) has been applied to archaeological samples at the Portuguese Research Reactor (RPI) since 1973, and number of analysed increased steadily mid‐1990s. Archaeometric applications INAA RPI include ceramics stones used in monumental architecture (menhirs) other historical monuments. A programme also exists for measuring precision contributing certified values geochemical reference samples. In addition, study interference factors is performed obtain...
AMS radiocarbon and OSL dating, profiling were used to directly delimit periods of variscite production at Pico Centeno Mine 2. These results integrated with analysis other well-dated establish an Iberian-wide chronological framework. Variscite 2 began ~ 5200 BC, coincident alpine jade or Casa Montero Iberian flint production. was only occasionally, together greenstones, during the 5th 6th millennia BC. During 4th millennium use increase its apogee in first half 3rd BC when it appeared...
Ion-beam-induced luminescence (IBIL) measurements were performed in Cr-doped β-Ga2O3 using both protons and helium ions, showing a strong enhancement of the Cr3+ upon ion irradiation. Theoretical modelling IBIL intensity curves as function fluence allowed estimating effective cross-sections associated with defect-induced quenching processes. The results suggest that sensitizing is more efficient for H+ than He+ Thermoluminescence (TL) studies pristine sample, no TL signal being observed...
This paper focuses on plain, stylistically unvaried pottery from three Late Neolithic sites the Mondego Plateau, Portugal, and investigates ceramic production exchange among small‐scale prehistoric societies by means of thin‐section petrography chemical analysis (INAA). The results show that majority was made with widely available, granite‐derived sedimentary clays, but petrographic differences between fabrics indicate collection at multiple locations within these deposits. Variation in...
In developing countries, the recovery of valuable materials from Waste Electrical and Electronic Equipment (WEEE) is carried out via uncontrolled practices, posing potentially severe risks both to human health environment. The assessment risk, which depends on kind hazardous properties substances contained in WEEE, currently limited as exposure scenario for single informal practice cannot be fully characterized this purpose. context, work proposes evaluates a strategy identify relative...
This paper discusses the archaeological research and historical contextualisation of Alto da Raia enclosure located on border between northern Portugal Galicia, identified as a possible Roman camp, following an interdisciplinary multi-proxy approach. included excavation, remote sensing geophysical survey, well sample collection for archaeobotanical geochemical studies by means chemical mineralogical analyses absolute dating using radiocarbon luminescence protocols. The results seem to...
