TracEnviSoil - Tracing metal(loid) and rare earth elements contents in alluvial soils of Baixo Vouga Lagunar: Origin, availability and environmental issues
The Baixo Vouga Laugar (BVL) is a very particular example of the harmonious coexistence between man and nature. This region, characterised by highly productive soils, enticed humankind to take advantage of its land and surface water reservoirs for the development of various agricultural practices (e.g., rice paddies, cornfields, pasture, among others). The high fertility of BVL's soils is owed to their development under the influence of alluvial deposits, materials with loamy texture, high porosity and marked organic matter enrichment. However, as demonstrated by the results obtained in other OHM projects, some of these soils are enriched in several potential toxic elements (PTEs). For this reason, the TracEnviSoil project intends to obtain a screening of the distribution of metal(loid)s of greater concern, as well as of rare earth elements (REEs), in order to ascertain the most probable sources (geogenic versus anthropogenic) of these trace elements, but also their (bio)availability and eco-toxicity in agriculture soils. This would allow to infer the potential risks for soil productivity, by creating harmful conditions for the soil microbiome and plant growth. Finally, the bioaccumulation of PTEs in the edible parts of plants will be evaluated in order to estimate the risk of their entry into the food chain, namely of animals and humans that feed on the vegetable products grown on these soils.

Nuno Durães finished his degree in Geology at the Faculty of Sciences of the University of Porto 2004. In 2006, he completed the Specialization Course of the Master in Prospecting and Evaluation of Geological Resources - Branch of Mineral Resources at the same institution. He concluded his PhD in Geosciences in 2011 at the Faculty of Sciences of the University of Porto and University of Aveiro. Between 2012 and 2019 he was a Postdoctoral fellow of Foundation for Science and Technology. He is currently a researcher at the GEOBIOTEC research unit (Department of Geosciences of the University of Aveiro). His research has been focused mainly on the areas of environmental geochemistry and biogeochemistry. To date, he has 33 publications, 71 communications in national and international conferences and a h-index of 11. He is also a reviewer of 21 journals indexed to the Journal Citation Report. He was principal investigator for 2 scientific research projects and a research team member for 11 projects. He was/is supervisor of PhD and master students. He also participated in more than 30 specialized courses and seminars, collaborated in the organization of several scientific activities or events (organization of scientific meetings; coordinator and guide of scientific dissemination activities) and in consultancy provision services.


Luís Portela completed his licentiate degree in Biology and Geology at the University of Aveiro (UA) in 2016. In 2018, he concluded his master’s degree in Geomaterials and Geological Resources at the UA and Faculty of Sciences of the University of Porto. He is currently attending the third year of the PhD Programme in Geosciences at the same institutions. During his academic career, he has deepened his skills in fieldwork, namely in the description and macroscopic characterisation of outcropping lithologies and geological mapping, as well as in the elaboration of geological and spatial-variation maps using ArcGIS software. His research has been mainly focused in the areas of geochemistry, petrology and Sr-Nd isotope geology of igneous and metamorphic rocks, but recently he has also been investigating water-rock interaction processes. To date, he has two papers published and indexed in SCOPUS; has five extended abstracts in national and international conferences, presented in...
