Mercury sources, distribution and bioavailability in the North Pacific Ocean

Source: Global biogeochemical cycles, vol.23 (2009)
"Scientists have known for some time that mercury deposited from the atmosphere to freshwater ecosystems can be transformed into a highly toxic form of mercury called methylmercury. In contrast to the growing knowledge base on the processes leading to the production of methylmercury in freshwater ecosystems, very little is known about marine systems. This new paper provides a significant step toward understanding oceanic methylmercury sources."
