摘要: Size-differentiated concentrations of SPM, F, Cl, NO3, SO4, Na, K, Ca, Mg and NH4 in atmospheric aerosols were measured a suburban area Agra city during December 1992 to March 1993. Except for NH4, Cl all components found have bimodal distribution. The fine fraction was dominated by NO3 while Mg, F contributed the coarse fraction. Fifty-eight percent SO4 67% mode comprised 42 33% respectively. peak above submicron range at 1.1 µm which has been attributed secondary sulphate formation heterogeneous oxidation SO2 on alkaline particles Ca Mg. total aerosol basic nature soil-derived acid neutralising (Ca, Na).
