Residence Times And Temporal Variations Of 210Po In Aerosols And Precipitation From Southeastern Michigan, United States, Daphne Mcneary, Mark Baskaran

Environmental Science and Geology Faculty Research Publications

Daughter products of ²²²Rn (such as ²¹⁰Pb, half-life = 22.1 years, and ²¹⁰Po, half-life = 138 days) have been widely used as tracers to determine the removal rates of aerosols as well to obtain analog information on the behavior of other chemical species in the lower atmosphere. To establish the first data set on the depositional fluxes of ²¹⁰Po in bulk precipitation and concentrations in air samples from the midwestern United States, we measured the depositional fluxes of ²¹⁰Pb and ²¹⁰Po in the bulk (wet plus dry) and dry fallout by deploying a rain …
