Abstract

The increased mercury content in a Greenland ice sheet over the last several decades suggests the dissemination of this element about the earth's atmosphere through the activities of man. The mercury content in the atmosphere appears to result primarily from the degassing of the earth's crust. Increased flux may come about as a result of the enhancement of this degassing process through the actions of man.

摘要

过去几十年间，格陵兰冰盖中汞含量的增加表明，人类活动致使这种元素在地球大气中扩散。大气中的汞含量似乎主要源于地壳的脱气作用。人类活动增强了这种脱气过程，可能导致汞通量增加。
