Abstract

Abstract

Atmospheric deposition of ²¹⁰Po and ²¹⁰Pb were measured at a time-series station in the southeast of China (Xiamen) from 2013 to 2014. The daily deposition fluxes of ²¹⁰Po and ²¹⁰Pb are (65.38±4.79)mBq/(m²·d) and (0.78±0.09)Bq/(m²·d), respectively, and the flux values present a significant annual variation. High fluxes occur in months with northeast monsoon, and low values are observed in the southwest monsoon prevailing months. In 2013 and 2014, the yearly deposition fluxes of ²¹⁰Po are 19.29 Bq/(m²·a) and 9.25 Bq/(m²·a), and ²¹⁰Pb fluxes are 159.2 Bq/(m²·a) and 189.6 Bq/(m²·a), respectively. The deposition fluxes of ²¹⁰Po and ²¹⁰Pb show inter-annual variations. There is a significant linear positive correlation between the ²¹⁰Po and ²¹⁰Pb fluxes. In addition, good positive correlations between rainfall and the deposition fluxes of the two nuclides are observed. These results reveal that the predominant removal passage of ²¹⁰Po and ²¹⁰Pb is precipitation along with rainfall, providing insights into understanding the transport of aerosol via ²¹⁰Po and ²¹⁰Pb. The datasets would provide an atmospheric source term for budgeting ²¹⁰Po and ²¹⁰Pb in waters of the western Taiwan Strait.
