  - 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.

Manuela Inácio	2015	Ecotoxicological and human health risk assessment of organic contaminants in Estarreja area – preliminary studies	Human health Ecotoxicology Risk assessment Environmental pollution Environment quality Environmental matrices Organic pollutants	Environmental matrices such as soils, plants, superficial waters and aquatic organisms can be an indicator of the environmental pollution since they could contain high levels of organic pollutants (OPs) influencing the environment quality and consequently human health. OPs are resistant to degradation and can persist for long times in the environment. These compounds can be transported by wind for long distances and can also easily enter the food chain. People are exposed to OPs by ingestion, inhalation and dermal uptake, causing adverse effects in human health due to their carcinogenic and mutagenic nature. The exposure risks to ecosystems and human health will be assessed and monitored on some environmental matrices presents in Estarreja, a very important industrial zone. OPs bioavailability will be assessed and quantified through chemical extractions. Bioacessibility tests will be performed in order to infer about the OPs concentrations that can beincorporated by plants and organisms and eventually reach humans. This study aims to contribute to a better insight on the behaviour of OPs in the ecosystems dynamics and infer about the real human exposure risks. This research work will improve current scientific knowledge about the possible existent contamination by the several OPs, risk assessment and environmental quality of Estarreja area. Assessment of the bioavailability of pollutants and human health risks will be performed through: chemical extractions and also bioaccumulation, bioaccessibility and ecotoxicological studies. It will give us new data about toxicity and bioavailability of present OPs. The main focuses are: 1. Analysis of the contamination levels presents in some environmental matrices (soil, plants, superficial waters and aquatic organisms) in Estarreja area; 2. Evaluation of contaminants bioavailability and bioaccumulation levels by using chemical extraction procedures and by evaluating the accumulation of OPs in plants and aquatic organisms; 3. Quantification of OPs bioaccessibility, namely through physiologically based extraction tests on soil, plants, superficial waters and aquatic organisms; 4. Integration of the obtained results in order toassess risks for human health by describing the contamination levels with OPs and their availability to be up taken by humans; at the end, soil and water quality will be linked to the global ecosystem health. 5. Contribute to define criteria for OPs contamination accepted levels based on potential health risks to humans and define protection strategies for this type of contamination.	OHM Estarreja		Afficher
