Investigator calls for limits on level of mercury present in fish that people should consume

A study led by investigator Filipe Costa at the University of Coimbra has concluded that there is a universal lack of methodology in evaluating the level of mercury (a toxic heavy metal) present in fish and shellfish that people can safely consume. Published in “Marine Pollution Bulletin”, the study recognises that “in very low concentrations, mercury does not represent danger for human health. But its accumulating long term can have prejudicial effects”.
