Indian Journal of Environmental HealthSummary: Dry deposition rates of major water soluble species F,C1, No3,SO4,NH4, Na, K, Ca and Mg were estimated at Dayalbagh, Gopalpura, Etah, Budaun and Mainpuri, F, C1,No3 and SO4 were measured by Ion Chromatography (Dionex), NH4, colorimetrically, and Na, K, Ca and Mg were determined by Atomic Absorption Spectometry. Deposition rates of the crustal components (Ca, Na and K) wer higher due to their large mass median diameter. The dry deposition rates of NO3 and SO4 were also similiar to crustal components suggesting a common origin. Spatial variations in dry deposition of ions were determined by calculating maximum/minimum ratio. On this basis the ions could be divided into two classes; low (<2) and high (>3). Low class included the crustal components showing minimum variability while NO3 and SO4 showed spatial variation. Deposition rates of ions are more in winter than summer at the selected sites. - Reproduced
