The activity concentrations of 210Po and 210Pb in atmospheric particulate samples collected in South Italy (Taranto) in Nov 2008 and in May 2009 were determined. The corrected activity concentrations of 210Pb and 210Po in sampling time were in the range of 11.9-122 μBq m-3 and of 300-1105 μBq m-3, respectively. The 210Po/210Pb activity concentration ratios were in the range of 0.0273-0.174. Based on the 210Po/210Pb activity concentration ratios in air particulates, the atmospheric residence times of aerosol in South Italy were estimated, which are ranged from 8.89 to 49.7 days. The calculated residence times are very useful for simulating and modeling the atmosphere transport process of the inorganic and organic pollutants in air in the studied region.
