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.
