AgrInfluenceEstarreja has always been a region with extensive farming areas, developing parallel and competing for land with an important industrial pole - the Estarreja Chemical Complex (ECC). For decades, the different ECC industries disposed solid wastes directly on the permeable sands without any kind of containment or impermeabilization, and discharged liquid effluents directly on streams connected to the coastal lagoon, without any previous treatment. Nowadays, the increasing of environmental consciousness led to an improvement of waste management practices. Although there are still signs of long term soil and groundwater contamination and the extension and persistence of contaminants are not fully understood, in part due to geological features (unconsolidated detritic sedimentary rocks) that allows the contaminant’s dispersion and cause high aquifer vulnerability.

Pore waters are very specific solutions, generally with high concentrations due to the greater residence time than percolation waters, which promote a high water-soil interaction. For this reason these solutions are the transference medium for excellence of inorganic and organic compounds between soils and plants. In this sense, the study of pore waters can give valuable information about the mobility and bioavailabitity of contaminants for plants.

In this project we propose to study the influence of the agriculture practices in the contaminants mobilization, focusing in pilot contaminated areas of Estarreja, and using pore waters as a medium to study these processes, hoping to contribute with valuable information to improve de quality of agriculture practices in the reduction of contaminant’s exposure.

Nuno Durães finished his degree in Geology at the Faculty of Sciences of the University of Porto in 2004 and in 2006 he completed a Post-Graduation in Prospecting and Evaluation of Geological Resources - Mineral Resources in the same institution. He completed his PhD in Geosciences in 2011 by Faculty of Sciences of the University of Porto/University of Aveiro. Currently he is a postdoctoral fellow at GEOBIOTEC research center (University of Aveiro). His research has focused mainly on the geochemistry and mineralogy of the supergenic environment, environmental geochemistry and biogeochemistry. To date, he has 23 publications and 46 communications in national and international conferences. He was principal investigator of a scientific research project and a member of other 7 scientific projects.



Anabela Cachada is a PhD student in the area of Environmental Chemistry and she has a degree in Environmental Engineering and of the Natural Resources (University of Trás-os-Montes e Alto Douro, Portugal) and a Master in Geochemistry (University of Aveiro, Portugal).

Her field of expertise in on the behaviour of organic contaminants in different environmental compartments, and she is particularly interested in the risk assessment of organic contaminated soils and in the evaluation of organic contaminants bioavailability and bioacessibility in soils. She has developed several works on the development of methodologies for the determination of organic contaminants in different environmental matrixes. She was a member in 9 multidisciplinary research projects (including two European funded projects) and she published 21 papers in international scientific periodicals with referees. She has presented 8 oral communications in international conferences and 5 in national conferences, and...


Carla Alexandra de Figueiredo Patinha have a Degree in Geological Engineering by the University of Aveiro, M.Sc. degree in Geochemistry and a PhD in Earth Sciences by the same institution. In June of 2005 began her activities at Geosciences Department of the University of Aveiro as Superior technician, assuming the management of geochemistry and hydrochemistry laboratories at the University of Aveiro.
