Magnitude of lead flux to the atmosphere from volcanoes
Pb/S, Tl/S and Bi/S ratios were measured in eruptive and fumarolic volcanic gases and indexed to the global flux of volcanic S to characterize approximate global volcanic emissions of these three metals to the atmosphere, which are about 1200 tons Pb/yr, 600 tons Tl/yr, and 4000 tons Bi/yr.
