Abstract
Aerosol samples were collected at Naha, Okinawa Prefecture, Japan during July 2001 to March 2005 to elucidate the concentrations of chemical components, including 210Pb, present in air for a sub-tropical region of Japan. The NO3-, SO42-, NH4+ and Ca2+ concentrations had clear seasonal variations and were high in winter to spring and low in summer. 210Pb concentrations ranged from 0.10 to 1.52 mBq m-3 and were low in summer and high in the other three seasons. The source of sulfur compounds in the aerosol samples was clarified by combining the sulfur isotope ratio δ34S and 210Pb concentrations. The multi-isotope method using δ34S and 210Pb concentrations was judged to be a good tool for understanding the transported sulfur source.
