The chemical compositions of negative ions in the lower atmosphere (0-30km altitude) at middle latitudes were investigated with two models, one for the lower stratosphere (15-30km) and the other for the troposphere (0-15km). The calculated result shows that the predominant ion species are NO_3^-HNO_3H_2O in the height range of 0-10km and NO_3^-(HNO_3)_2 in 10-30km, and other main negative species have NO_3^- or HSO_4^- cores. In general, the calculated result agrees with the observed one. A possible role of the ions and aerosols generated by the ion-nucleation mechanism is suggested for the Antarctic springtime 'ozone hole' phenomenon.
