Jean-Philippe Bedell	2017	Bioavailability and ecotoxicology assessment of organic contaminants presents in Estarreja soils	Ecotoxicology Bioavailability Mobility Risk assessment Organic pollutants Emerging contaminants Soils Earthworms Plants Environmental pollution 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).

Ecotoxicology Bioavailability Pollutants mobility Risk assessment Organic pollutants Emerging contaminants Soils Earthworms Plants Environmental pollution Environmental quality	Soil, an important environmental compartment, is largely affected daily by anthropogenic activities such as industries, traffic and waste disposal.

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.	OHM Estarreja OHM Vallée du Rhône	Afficher

Ruth Pereira	2017	NAMELESs - Nanomaterials for the Remediation of agriculture Metal contaminated soils surrounding the Estarreja chemical complex	AGRICULTURAL SOILS BIOAVAILABILITY FOOD SECURITY INDUSTRIAL ACTIVITY NANOPARTICLES POTENTIALLY TOXIC ELEMENTS SOIL 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.

Myriam Janin	2016	TRACE-DUST: Chemical and isotopic properties as tracers of airborne particles collected from the Estarreja and Provence OHMs: implications to exposure and human health risk assessment	Airborne particle matter Potentially harmful elements Chemical and isotopic tracers Bioavailability Inhalation route Health risks Air pollution	Toxic concentrations of potentially harmful elements in ambient air can lead to (1) hazardous impact of airborne PM in the health of the population and (2) contamination of water supplies, edible crops and human food supply. Estarreja and Provence regions are impacted by industrials activities, road traffic and growing urbanization and their air quality degradation is a major issue in terms of health risks and environmental impact. Exposure to PM has been associated with respiratory symptoms, decreased lung function, worsening of asthma and the development of chronic bronchitis. Considering that dust is the most important contributor for nonpoint source pollutants to aquatic and terrestrial systems, dust deposition data is relevant information to assess potential impacts on humans and ecosystems. This multi-proxy study aims at correlating dust origin (using isotopes “fingerprints”) and physicochemical dust properties, to potential risks (magnitude of exposure and bioavailability) in terms of human health and environmental effect.
