Studies have found that over the last several decades, the increase has been by as much as a third in the waters of the Pacific, and now, new studies are proving that the mercury level is rising in Yellowfin Tuna, as well. The study found that the rate at which mercury levels have been increasing in these fish since 1998 is roughly 3.8% annually. Ultimately, the study notes that this is due to the human-factor that’s associated with climate change. As we continue to pump more, and more pollutants into the atmosphere, those toxic elements – like heavy metal mercury are becoming increasingly prevalent in the ocean food chain.
