Portuguese Researcher Advocates for Universal Method for Measuring Mercury in Fish



Portuguese Researcher Advocates for Universal Method for Measuring Mercury in Fish

A study by a researcher at the University of Coimbra concluded that there is no universal methodology for assessing the levels of mercury in fish and shellfish that the body can digest.

Study published in the journal Marine Pollution BulletinPoint at “the need to create a universal methodology for assessing the bioavailability of mercury (Hg), a toxic heavy metal”in fish and shellfish species, the Faculty of Science and Technology of the University of Coimbra (FCTUC) said today in a press release sent to Lusa.

Bioavailability “translated as what the human body can absorb from the food” it consumes.being a relevant tool for determining the maximum values ​​of pollutants that can be consumed throughout life without risk to health.

“In very low concentrations, mercury does not pose a risk to human health, but its long-term accumulation can have harmful effects,” he emphasizes.

In this sense, a study led by a researcher from the Center for Functional Ecology Filipe Costa sought to evaluate “the fraction of bioavailable mercury in fish and shellfish found in the Mediterranean diet”namely species caught in the ocean (black swordfish, tuna, swordfish, blue shark), aquaculture species (salmon and mussels) and estuarine species (mullet and clams).

The results of the study show that the bioavailable mercury found in these fish and shellfish species “especially after cooking, this is far below the levels set by current safety risk assessment legislation.”

However, the group, which also includes researchers from the University of Aveiro, noted “that the assessment of the bioavailability of mercury in fish and shellfish depends on the method used, since each extraction method gives different results.”

“Among the three extraction methods tested, the Unified Bioavailability Method (UBM) gave the highest rating for mercury bioavailability to consumers.”the press release says.

Cooking reduces mercury

Regarding the cooking methods used, “they all significantly reduced the proportion of bioavailable mercury”, that is, there was a “reduction in the content of this pollutant”, said Filipe Costa, quoted in the note.

FCTUC reports that “Current food safety legislation only considers the total concentration of contaminants in fish and shellfish, without taking into account the bioavailability of the contaminant during digestion and the effect of cooking regimes on the solubility of the contaminant in the digestive tract.”

Maestro de Braga is the first Portuguese in the National Symphony Orchestra of Cuba.



Maestro de Braga is the first Portuguese in the National Symphony Orchestra of Cuba.

Maestro Filipe Cunha, Artistic Director of the Philharmonic Orchestra of Braga, has been invited to conduct the Cuban National Symphony Orchestra, as announced today.

According to a statement sent by O MINHO, “he will be the first Portuguese conductor to conduct this orchestra in its entire history.”

In addition to this orchestra, the maestro will also work with the Lyceo Mozarteum de la Habana Symphony Orchestra.

The concerts will take place on 4 and 12 March 2023 at the National Theater of Cuba in Havana.

In the words of the maestro, quoted in the statement, “these will be very beautiful concerts with difficult but very complex pieces” and therefore he feels “very motivated”.

From the very beginning, Rachmaninoff’s Piano Concerto No. 2 will be performed by an Italian pianist (Luigi Borzillo), whom the maestro wants to bring to Portugal later this year. In the same concert, Mendelshon’s First Symphony will be performed.

Then, at the second concert, in the company of the Mexican clarinetist Angel Zedillo, he will perform the Louis Sfora Concerto No. 2. In this concert, the maestro also conducts Tchaikovsky’s Fifth Symphony.

“This is an international recognition of my work. An invitation that I accept with humility and great responsibility. I was surprised to learn that I would be the first Portuguese member of the Cuban National Symphony Orchestra. This is a very great honor,” the maestro said in a statement.

“I take with me the name of the city of Braga and Portugal with all the responsibility that goes with it, and I hope to do a good job there, leaving a good image and putting on great concerts. These will be very special concerts because, in addition to performing pieces that I love, especially Rachmaninov and Tchaikovsky, I will be directing two wonderful soloists who are also my friends. It will be very beautiful,” concludes Filipe Cunha.
