One study shows "no significant differences in mercury levels in tuna, bluefish, and flounder as a function of type of store or economic neighborhood". However, some types of fish contain a lot higher mercury levels than others. [66], Controlling output of mercury pollution sources, The mercury levels in the table, unless otherwise indicated, are taken from the.
