Environmental quality
Soil, an important environmental compartment, is largely affected daily by anthropogenic activities such as industries, traffic and waste disposal. These activities can bring to the soils large quantities of several contaminants and consequently they can easily enter the food chain and the trophic scale of ecosystems via plants and animals.
This type of organic pollutants can persist for long times in the environment, being susceptible to transport for long distances, then they can easily reach a large geographic area and be widely dispersed.
It is of an extreme importance to assess the environmental and human health risk pose by this problem. In this work, an evaluation and a comparison study will be done through bioavailability tests and ecotoxicological bioassays with plants and invertebrates in order to assess the real risk inherent to the presence of such pollutants in soils of an important industrial area: Estarreja (Portugal) as well as in the“casiers Girardon” of Rhône river (France). These constructions were responsible for significant changes in the sedimentation processes in the river banks especially during overflow episodes. Sediment deposition can lead also to several ecosystem and health risks once some inorganic and organic pollutants can be associated to these sediments.

A transformação de ecossistemas nativos em áreas agrícolas, industriais ou urbanas é uma das maiores causas de perda de biodiversidade, a nível global. A gestão sustentável pode auxiliar na conservação do património natural, de forma integrada com outros usos do solo. Para tal, é crucial a integração do conhecimento sobre os ecossistemas com a matriz cultural e socioeconómica de uma região. A paisagem do Baixo Vouga Lagunar caracteriza-se por um mosaico de habitats naturais e antropogénicos. Este projeto tem como objetivo promover a gestão e conservação mais eficiente dos valores naturais da região, de forma integrada com a sua matriz cultural e socioeconómica, e contribuir para o aumento da resiliência do mosaico de habitats num contexto de alterações globais. O projeto resultará na identificação de áreas prioritárias para conservação e de boas práticas, que conciliem a preservação dos valores naturais e a viabilidade económica e o património cultural da região.

Estarreja is a highly industrialized area with high prevalence of respiratory diseases, however there is limited information on the determinants of respiratory health of Estarreja inhabitants’. The present project aims to describe the status of respiratory health in a representative sample of Estarreja adult population and understand the key environmental factors that affect the respiratory health of Estarreja inhabitants’. In this sense, the indoor environment will be characterized in terms of microbiome, and in terms of chemical contaminants. Additionally, the burden of chemical contaminants will be evaluated in human samples and the oxidative stress characterized. Our goal is to unravel possible associations between the indoor contaminants and the exacerbations symptoms in patients with respiratory diseases so that guidelines regarding the minimization of exposure can proposed in order to reduce exacerbations and prevent new cases, which ultimately may be translated into a better respiratory health status of the Estarreja population.

RISK ASSESSMENT.
Estarreja Chemical Complex (ECC) is the second largest chemical complex in Portugal and has been classified by the Portuguese Environmental Agency as a "site of priority actions in terms of rehabilitation". Previous studies found that potentially toxic elements (PTEs) in Estarreja agricultural soils are associated with labile fractions, which results in their bioaccumulation and translocation in plant tissues of commercial interest, and a potential risk of transfer to the food web.
Since nanotechnology has been presented as a promising technique for immobilising PTEs in soils, and particularly for reducing available contents, this project aims at evaluating the ability of nanoparticles to reduce PTEs mobility and their uptake by plants. The ability of nanoparticles to reduce the mobility of PTEs will be assessed though selective chemical extractions and by ecotoxicological assays.
Thus, this project proposes to study the effectiveness of the use of nanoparticles usually employed into remediation strategies of contaminated soils to determine the changes in the mobility of potentially toxic elements assess the ecotoxicity of nanoparticles in laboratory conditions and evaluate the reduction of bioaccumulation and translocation of PTEs by plant species.

Agriculture is an important sector in Estarreja region, in terms of landscape occupation and socio-economic input. However, due to the environmental impacts of the industrial sector and natural environmental change, local resources such as groundwater are known to be degraded and contaminated. Particularly, a certain level of soil and water salinization has been observed. Therefore, there is an arising demand for developing new farming practices for maintaining healthy and productive terrestrial ecosystems, together with efficient use of local resources. The main objective of this project is to suggest a farming practice (No-tillage) which contribute to environmental and ecological conservation and preservation of soil quality. Thus, the efficiency of No-tillage will be discussed through an experimental design for testing effects on farm soil parameters, soil retention function and crops production. In addition, a comparative study between the present farming practice and the proposed one will be attained.

Narrativas mediáticas sobre o CQE
Risco ambiental e seu tratamento mediático.
Desde a sua criação, o Complexo Químico de Estarreja (CQE) introduziu transformações reais na vida quotidiana das populações do concelho de Estarreja, no seu poder económico, nos seus hábitos e práticas de consumo, na sua paisagem e meio ambiente. O aparecimento e desenvolvimento das empresas que formam o CQE não se fez sem custos ambientais e sem colocar, às populações envolventes e aos ecossistemas naturais, riscos relevantes que se materializaram em alguns casos em problemas concretos de poluição atmosférica, dos solos e da água, com impactos ambientais evidentes e igualmente na saúde humana e nas atividades económicas, particularmente na agricultura.
O CQE integra estabelecimentos industriais que possuem grandes quantidades de substâncias perigosas cujo o transporte, armazenamento, manuseamento e transformação configuram situações de risco de acidentes industriais graves, quer para os próprios trabalhadores, quer para a população envolvente. Esta circunstância contribui para ‘marcar’ o território local, conferindo-lhe uma identidade bastante específica no contexto regional e nacional, bastante assente na indústria química e, sobretudo, nos riscos que a mesma foi representando, ao longo dos últimos 60 anos.
Estas características, especialmente os aspetos associados ao risco, concorrem para a constituição do CQE como objeto potencialmente mediático, ou seja, potencialmente alvo da atenção dos meios de comunicação social, essencialmente de âmbito regional, mas igualmente à escala nacional.
O objetivo principal deste trabalho é a análise do tratamento mediático dado ao CQE pela imprensa escrita nacional, no sentido de contribuir para a reconstituição da história do Complexo e da sua relação com a envolvente.

SOILSALT - Benchmark of soil salinization on "Baixo Vouga Lagunar" before the floodbank construction
Benchmark
Saline soil
Baixo Vouga Lagunar
floodbank construction
The Ria de Aveiro has been subdue to Human action to enable the lagoon harbour navigability. The most visible impact has been at Baixo Vouga Lagunar (BVL), were the land has been affected by surface saltwater intrusion. Salinization reduces soil productivity, causing the abandonment of agriculture. The completion of the floodbank construction will carry out environmental/ecological changes in the BVL. It is expected to avoid surface saltwater intrusion, however this cannot ensure the absence of saline groundwater intrusion. Hither way it is crucial to acquire benchmark conditions before the intervention in order to monitor the future evolution of the salinization process in BVL. SoilSalt will provide the benchmark for the actual status, extension and degree of soil degradation that will support the identification of potential future hazards or salinization attenuation processes. SoilSalt aims establishing the link between farmers and academics supporting the development of the Estarreja Strategic Development Plan 2015-2025.

sciences de l'éducation
Le projet s'inscrit dans une vision d'éducation au développement durable, porté en partie par les sciences de l'éducation et plus généralement les sciences sociales s'intéressant à la coordination d'action collective et aux moyens de l'améliorer. L'aspect éducatif est abordé par l'intermédiaire d'un jeu, déjà construit pour représenter des éléments structurels liés à la problématique des boues rouges traitées dans le cadre de l'OHM bassin minier. Ce jeu se veut facilement utilisable par des enseignants ou des animateurs souhaitant se l'approprier pour des publics divers - il n'a pour autant pas encore été testé suffisamment pour garantir que l'aspect éducatif soit atteint - que ce soit pour apprendre des modèles de processus, ou des comportements d'arbitrage liés à des interactions sociales et économique liées à la co-action autour de biens communs. Le but du projet est donc d'établir un réseau de chercheurs, d'école et éventuellement d'associations et de tester le même jeu dans diverses circonstances autour d'une grille d'analyse commune. Le jeu dans une version stabilisée et approuvée, ses modifications éventuelles (généralisation), le protocole construit, ainsi que le réseau d'école en contact et impliquée, seront les résultats du projet.

Arsenic levels in the placental-fetal unit: a case study in parturient from Aveiro district
Arsenic
Biomarkers of exposure
Epidemiology
Maternal transfer
Placenta
Umbilical cord
The Estarreja Chemical Complex (ECC) located in the Aveiro district is one of the major industrial areas of Portugal and contamination by the metalloid arsenic (As) has been documented for this area. Therefore, human exposure to As needs to be evaluated in this region, particularly in sensitive windows of exposure such as the prenatal period. In this context, the main goal of this project is to assess the maternal-fetal transfer of As in women living in the Aveiro district. In this work we will assess maternal and fetal exposure to As using potential non-invasive biomarkers of exposure (As levels in placenta, amniotic membrane and umbilical cord) in order to improve the knowledge about the As retention over the maternal-fetal-placental unit. The potential influence variables (sociodemographic factors, drinking water, food habits and lifestyle) that contribute to maternal and fetal exposure to As during pregnancy will be investigated. Furthermore, the effects of As accumulation patterns on oxidative stress, neurotoxicity and genotoxicity biomarkers will be evaluated in placental tissues. The distribution of As levels along the different counties of the Aveiro district will be one of the main focus of this research project. This will improve the knowledge on the exposure to As in the Aveiro district, and will provide relevant information for the potential action of local authorities if results show concern to human health.

Climate change is enhancing the effects of anthropogenic pollution, leading to severe impacts on inland water systems and posing risks to human health. Therefore, adaptation and mitigation actions for these major challenges related to water quality are crucial but must start involving local populations in the decision-making processes. Citizen science approaches can be a powerful tool for engaging citizens and scientists for a same purpose through a responsible and conscious action, taking advantage of recent technology.
The CITAQUA project is a Citizen Science approach for Estarreja population through the monitoring of the downstream section of Antuã River and wells/boreholes from the surrounding areas, concerning nitrates and faecal contamination, two important water quality problems at this region. CITAQUA is expected to increase awareness about water quality and impacts from climate change and anthropogenic activities, by connecting academic scientists with local authorities and citizens (with a special focus on Youth).
