  - 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.

Anabela Pereira	2016	Impact of phytoremediation processes on bacterial communities from Pb and Cd contaminated soils: a greenhouse experiment	heavy metals phytoremediation bacterial communities	Human activities such as industry and agriculture have resulted in the high contamination of soil and water with heavy metals. This type of contamination induces harmful effects on environmental and human health. In the last years, research on phytoremediation has highlighted the scientific and economic benefits of plants and their associated microorganisms used for the reclamation of polluted soil and water. Also, the potential of microorganisms to enhance phytoremediation processes and the exact mechanism by which bacteria could enhance heavy metal accumulation in plants has been received some attention. Despite the great interest in improving the efficiency of metal hyperaccumulating plants, their influence on microbial community’s remains poorly elucidated, constituting a less explored aspect in phytoremediation processes. The aim of this study is to investigate the impact of the plant hyperaccumulator (Thlaspi spp.) on the diversity and structure of soil bacterial communities during phytoextraction processes. The present study aimed to assess the impact of the Thlaspy spp. on the bacterial communities along phytoremediation process in Cd and Pb-contaminated soil from Estarreja region. Results will contribute to establish efficient strategies of risk assessment and phytorremediation in Estarreja.	OHM Estarreja		Afficher
Olga Ameixa	2016	PHYTOREMEDIATION OF SALINE SOILS USING SALICORNIA RAMOSSISIMA (Acronym: RESTORE)	Phytoremediation Halopytes Salt contamination Soils Salicornia ramosissima	Baixo Vouga Lagunar (BVL) is an area with a strong and balanced relationship between man, land and water, recognized by its high biological diversity. However, the impact of human activity (e.g. changes in the system hydrology) combined with climate change (e.g. sea level rise), have already affected BVL, wherein areas are currently flooded by tides, and soils affected by surface saline intrusion. The conclusion of the dike, foreseen in a short term, is fundamental to save still existing agricultural areas and to reclaim flooded areas. However, it is necessary to remediate these soils from salt contamination in order to return them back to agriculture. In this context, we propose to conduct an innovative and multidisciplinary project, linking the team scientific knowledge on agriculture and soils, environmental chemistry and salt marsh ecology, in combination with local farmer’s knowledge. This proposal will integrate two of the topics proposed by OHM-Estarreja: Evolution of the Relations Between Society and Environment and Evolution of Biodiversity. We propose, to evaluate the potential of the autochthonous halophyte Salicornia ramosissima to remediate the BVL salt contaminated soils. Apart from having a phytoremediation capacity, S. ramosissima is currently considered a gourmet plant with high market demand as a green fashionable vegetable, dished up in fine restaurants all over the world. Hence, it can be grown as a cash crop and be an alternative in salinized soils for farmers in the region. RESTORE project can also serve as showcase for other coastal areas under treat due to salt contamination.	OHM Estarreja		Afficher
