  - 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.

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.
