Record #180916:

Seasonal Pb changes in snow from winter to early summer 1998 in Livingston Island, Antarctic Peninsula / Sungmin Hong.

Title: Seasonal Pb changes in snow from winter to early summer 1998 in Livingston Island, Antarctic Peninsula / Sungmin Hong.
Author(s): Hong, Sungmin.
Date: 2001.
Publisher: Ansan, Korea: Polar Sciences Laboratory, Korea Ocean Research & Development Institute
In: Proceedings of the joint international seminar Recent Interests on Antarctic Earth Sciences of Korea and Japan. (2001.),
Abstract: Presents data on short-term changes in concentrations of lead from shallow snow collected on Livingston Island, a location close to South America which is possible source region of anthropogenic Pb entering Antarctica. Pb concentrations in 26 snow samples ranged from 0.16 to 17.6 pg g⁻¹ with average of 4.97 pg g⁻¹, and pronounced spring maximum. Contributions from natural sources were estimated from Al and Na concentrations and average black carbon concentration reported in Antarctic Holocene ice, and were only ~25%. Excess Pb over Pb from natural sources is probably anthropogenic and due to long-range transport from South America. Results show that yearly Pb fallout flux is much greater in Antarctic coastal areas than at locations far from coast, indicating complex patterns of transport and deposition of pollutant aerosols. Recycling of anthropogenic Pb from seawater to atmosphere may significantly contribute to Pb fallout flux in Antarctic coastal regions.
