Pb isotope record over one century in snow from Victoria Land, Antarctica.
Earth and Planetary Science Letters, Vol. 232, Issues 1-2, 30 March 2005,
pp. 95-108 doi: 10.1016/j.epsl.2005.01.007
Pb and Ba concentrations and Pb isotopic compositions are reported
for firn core and snow pit samples from Victoria Land, Antarctica,
dating from 1872 AD to 1994 AD. From variations in Pb/Ba ratios
and Pb isotopic compositions, two periods of major Pb enhancements
were identified, from 1891 to 1908 AD and from 1948 to 1994 AD.
The earlier pollution event is attributed to Pb emissions from
non-ferrous metal production and coal combustion in the Southern
Hemisphere and is in excellent agreement with coincident pollution
inputs reported in firn/ice cores from two other regions of Antarctica,
at Coats Land and Law Dome. Using Pb isotopic systematics, it was
calculated that ~50% of Pb deposited in Victoria Land in 1897
originated from anthropogenic emission sources. The more recent
period of Pb enhancements, from 1948 to 1994 AD, corresponds to
the introduction and widespread use of gasoline alkyl Pb additives
in automobiles in the Southern Hemisphere, with anthropogenic Pb
inputs averaging 60% of total Pb but with large uncertainty.
Intra- and inter-annual variations in Pb concentrations and isotopic
compositions were evaluated in snow pits samples corresponding to the
period 1991-1994. Substantial variations in Pb/ Ba and 206Pb/207Pb
ratios were detected but the absence of a regular seasonal pattern
for these parameters suggests that the transport and deposition
of aerosols to the Antarctic ice sheet are complex and vary
from year to year.
STUDY NOTES: Victoria Land, Antarctica ice core and snow pit Pb and Ba
concentrations, and Pb isotope ratios, for the period 1872-1994.
Concentrations are accurate to ±15% (95% confidence interval).
Uncertainties in the isotope ratios are 95% confidence intervals.
