  - L'OHMI - Estarreja a été créé pour étudier les multiples effets de l'activité industrielle dans la municipalité d'Estarreja, et pour contribuer à l'amélioration de la connaissance de ses effets et évaluer les progrès résultants des interventions d'atténuation déjà développées dans la région.

  - L'OHM Estarreja étudie les multiples effets de l’activité industrielle développée sur la commune d’Estarreja, dans le but d’améliorer les connaissances sur ces effets, mais aussi d'évaluer l’évolution découlant des interventions de réhabilitation déjà entreprises dans cette zone.

The threatens to agriculture soils from the Estarreja and Baixo Vouga Lagunar (BVL) regions include the combination of several anthropogenic and environmental factors, such as industrial pollution, intensive farming practices, overuse of fertilizers, the use of contaminated groundwater for irrigation, and salinization due to surface saltwater intrusion. For instance, these factors contributed to land degradation and therefore to crop productivity and safety decreasing. Maize (Zea mays L.) is one of the most important crops in these regions and boosting maize production in affected soils can have a significant socio-economic impact. Thus, the need of sustainable and eco-friendly solutions to improve productivity is one of the major challenges of agriculture activity in these regions. Estarreja and BVL may also be living labs, providing experience to other sites, where these approaches may be transferred. Several studies have demonstrated that inoculation with indigenous rhizobacteria can enhance plant performance and growth. Driven by described issues and based on knowledges acquired from our previous OHM projects (e.g: SoilGenomic, 2016; NotillAgri-Estarreja, 2017; Nameless, 2017; SoilSalt, 2017; SoilRice, 2018), this proposal aims to explore the potential of a consortium of indigenous plant growth-promoting rhizobacteria (PGPB) that are resistant to metal(loids) present in those soils, as well as PGPB well adapted to high levels of salinity and re-applied them to reduce problems associated with stressful environments via ex-situ bioinoculation of new seeds (before sowing) and in-situ bioinoculation of new plantlets. Accordingly, this may contribute to minimizing impacts on crops productivity and assure more sustainable agriculture practices. ( 1 )

Global sea-level rise and eutrophication constitute serious threats to freshwater bodies worldwide, posing severe risks to economy and to environmental and human health. Given its location and its higher industrialization and population density, coastal regions are particularly in danger. It is predicted that coastal areas will suffer from seawater intrusion, causing salinization of freshwater and terrestrial systems. Furthermore, the excessive nutrient loadings from industrial and domestic effluents and leaching from agricultural fields may increase the risk for eutrophication. Consequently, these phenomena may potentially cause the deterioration of water quality and loss of aquatic fauna and flora. Even though some technologies are available in the market to remediate waters, there is a need to find more environmentally safe alternatives to overcome this problem without harming aquatic life. Innovative remediation alternatives based on nanotechnology, such as the use of layered double hydroxides (LDHs), are emerging and have proven to be suitable alternatives for remediation. The overarching aim of this proposal is to evaluate the potential of LDHs to remediate waters of Estarreja region. Even though waters from any region could be used for this purpose, waters of the Estarreja municipality are ideal for this project due to their low-lying coastal lagoon location and to the historically pressure from the intense industrial and agricultural activities. This study will provide information on the water quality and the degree of eutrophication and salinization of waters of Estarreja, and will promote the use of more sustainable alternatives for water remediation and water quality improvement.
