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.\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n NOAA National Centers for Environmental Information\r\n \r\n \r\n \r\n \r\n \r\n \r\n ncei.info@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov/contact\r\n \r\n \r\n NCEI Contact Information\r\n \r\n \r\n Information for contacts at NCEI.\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n \r\n \r\n distributor\r\n \r\n \r\n \r\n \r\n \r\n \r\n In most cases, electronic downloads of the data are free.
