Scientists study levels of toxic mercury in Antarctic seals, whales

February 20, 2024

Mojica, a Colombian marine biologist, descends from his boat alongside Livingston Island, in the South Shetland archipelago, to retrieve his sample. Mojica is studying the impact of mercury, used in activities such as mining thousands of kilometers away, on Antarctica's large mammals. Humpback whales consume large quantities of krill, small crustaceans susceptible to mercury contamination. Mojica will study the samples to determine if "mercury has been transmitted from one link to the next in the food chain." Artisanal mining is the main source of mercury emissions, where the element is used to collect gold by binding to it.
