It is reported that mercury levels have been increasing in fish. I was curious if anyone knew where I could find data showing mercury levels in various types of dietary fish and seafood, particularly tuna, over various years.
"Seafood data" is a Norwegian database where you can search for the presence of undesirable components and nutrient data in seafood. There are no data on tuna, but you can find values over years for other species. Take a look at: http://www.nifes.no/sjomatdata/index.php?page_id=&lang_id=2
Thank you, I am more looking for fish species that are more common in East Asian diets, however, and how those levels have changed over the decades
perhaps you will find some answers in those 2 papers and references therein:
