Summary

Recent investigations of lead concentrations in polar snows carried out in the Caltech ultraclean laboratory using mass spectrometric isotope dilution techniques confirm earlier work showing lead to be ∼1 pg/g in old (Holocene) Greenland ice.

These later studies also show that concentrations of lead in Antarctica are <4 pg/g in surface snows and ∼1 pg/g in ancient ice. It has not yet been possible for investigators to reduce lead contamination associated with collection procedures to allowable low levels in Antarctic surface snow. It will be necessary to inaugurate new and better collection procedures to solve this problem.
