Hugo Vieira 2022 Can I eat this fish? - Dietary recommendations to reduce the mercury risk exposure Risk-benefits analysis Society engagement Environmental and human health Food safety Dietary guidelines Estarreja region, located nearby Ria de Aveiro, is widely known for its mercury (Hg) historical contamination (e.g. Largo do Laranjo) due to previous activities of a chlor-alkali industry. At the same time, a variety of fishing activities are usual in this lagoon.
Due to its high nutritional value, fish and seafood consumption have been linked to the prevention of some human diseases, especially regarding cardiac and circulatory disorders. Unfortunately, fish and seafood are also considered as the major pathway of Hg exposure in humans. More than 90% of the Hg present in fish tissue is found mainly as methylmercury (MeHg), the most toxic form. Due to the potential adverse human health effects, international agencies have established Reference Doses (RfD) as recommendations concerning Hg intake.
Despite the recognized importance of fish/seafood to the human Hg intake, studies that assess this exposure risk in Portugal have been focusing on only some species and mostly restricted to Academia. In addition, scientific language is often not clear for the general public. So, in order to contribute to a knowledge transfer from Academia to Society, this proposal aims to evaluate fish consumption habits and potential Hg exposure of Estarreja population and to develop and share tools with simple and precise language that will contribute to an informed decisions on the consumption of fish/seafood involving not only decision makers and but also the target population.

Patrícia Santos 2015 ChemREs – Chemical Composition of Rainwater in Estarreja: identification of major contaminants (organics and inorganics), source assessment and evaluation of implications for the environment and humans Rainwater Dissolved organic contaminants Dissolved inorganic contaminants Source assessment Environmental risk Human health risk The present project intends to contribute to the knowledge of chemical composition (organic and inorganic) of rainwater in the city of Estarreja, identifying the major pollutants in the area, including tracers of anthropogenic activities. Thus, two distinct sampling locals will be used to evaluate the sources of pollution: one in the industrial area (industrial); and another out of industrial area, and near an agricultural area (industrial background/agricultural).
The influence of seasonality (with sampling in two distinct periods: warm and cold seasons) and of air masses trajectories on the chemical composition of rainwater will be also assessed. Moreover, will be evaluated the implications of the presence of contaminants in rainwater to the environment and to the human beings, since rainwater is a way of availability of freshwater.
The project involves a multidisciplinary team, with researchers from the Departments of Chemistry and Geosciences at University of Aveiro, with wide experience in assessment of organic and inorganic contamination in environmental matrices, including in rainwater.
This project is in the scope of "the OHM International Estarreja, which aims at studying the multiple effects of the industrial activity on the man-environment relationship, taking into account the temporal dimension, marked by changes in industrial practices". Furthermore, the proposed project is within the scope of the priority areas,
"Area 2: Public Health", more specifically "Organic Contaminants: agricultural origin/ industrial origin". In addition to organic contaminants the present project will also study the inorganic contaminants from agricultural and industrial origins.

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.
