摘要：

The 1977-1978 French New-Zealand summer campaign at Mount Erebus took place during a period of rather low activity. In such conditions, we could measure an output of 3 Ci of 210Pb, 100 Ci of 210Po and 1010 tons of sulfate per year. The 210Po seems to be the only element emitted by Mount Erebus whose contribution to the Antarctic atmosphere is significant: sulfur compounds as well as radon emitted by Mount Erebus during a period of quiescent activity, have a negligible contribution to the overall Antarctic budgets. The presence of long-lived radon daughters in volcanic gases, highly enriched in volatile elements, seems to be a characteristic of gases emitted directly from the magma at high temperature. © 1979.
