“…Po On a global-scale, it is generally accepted that the midlatitude regions have higher atmospheric deposition fluxes of 210 Pb compared to the Equatorial and Polar Regions (Schell, 1977) due to the coverage of water and snow in low and high latitudes, which results in less land exposure to surface air and successive less 222 Rn exhalation. 210 Po, a granddaughter of 210 Pb, is also speculated to have a similar spatial pattern (Yang, 2005).…”

Po deposition on seasonal timescales. There were significant positive linear correlations between the daily depositional fluxes and precipitation, supporting the predominant removal passage of 210 Pb and 210 Po through rainfall. The inverse relations between specific activities and precipitation indicated that the removal efficiencies were much higher at the beginning of rainfall. In contrast, the dry deposition only accounted for 22% and 29% of the bulk depositional fluxes of

“…[198lJ, TANAKA et al [1983J). SCHELL (1977) found that 2loPb residence times were lower in coastal and estuarine locations than in the open ocean. For example, in the Strait of Juan de Fuca the residence time was measured to be 58 days, compared to 2.6 y for an open ocean location in the same study.…”

“…Krishnaswami et al 197 1;Robbins and Edgington 1975;Benninger et al 1975;Dillon and Evans 1982). The residence time of 210Pb in the water is usually very short relative to that of the water itself (Schell 1977;Durham and Joshi 1980). Once incorporated within the solid phase of the sediment, the 210Pb is somewhat resistant to redistribution (Davis et al 1984).…”

Lake sediments reflect conditions in the water column and can be used for rapid, integrative measurements of limnological variables. Examination of 2LoPb-dated cores from 12 Florida lakes of widely differing trophic state (expressed as Carlson's trophic state index: TSI) shows that net accumulation rate of organic matter is related to primary productivity in the water column. In 26 other lakes the activity of unsupported *l"Pb g-l organic matter in surficial sediments is inversely related to trophic state and, therefore, to organic accumulation rate. From this observation we develop a new method that uses fallout *l"Pb as a dilution tracer to calculate net sedimentary accumulation rates of any material in surface mud. We demonstrate strong relationships between net loss rates of biologically important materials (C, N, P, and pigments) and their respective water concentrations (expressed as TSI). Multiple regression models incorporating net sediment accumulation rates of all four variables explain up to 70% of the lake-to-lake variation of TSI. The 210Pb-dilution method has applications for studies of material cycling, paleolimnology, and sediment accumulation processes.
