Abstract :Aerosol samples were collected at Naha, Okinawa Prefecture, Japan during July 2001 to March 2005 to elucidate the concentrations of chemical components, including ^<210>Pb, present in air for a sub-tropical region of Japan. The NO^-_3, SO^<2->_4, NH^+_4 and Ca^+_2 concentrations had clear seasonal variations and were high in winter to spring and low in summer. ^<210>Pb 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 δ^<34>S and ^<210>Pb concentrations. The multi-isotope method using δ^<34>S and ^<210>Pb concentrations was judged to be a good tool for understanding the transported sulfur source.
