摘要：Atmospheric samples of wet and dry depositions were collected on seasonal variation basis at varioussampling sites situated in five different zones from an industrial city Kota, India during 2012-2013. The analyticalresults show seasonal and spatial variation in metal concentration (crustal and anthropogenic) during monitoringmonths. Average concentrations of heavy metals (Cu, Cd, Zn and Pb) were higher in winter and lower in summer andreversed trend was observed in crustal metals (Fe, Ca and Mg). Overall, heavy metal concentrations showed thefollowing trend - Zn > Pb > Cu > Cd in both wet and dry depositions. Analysis of enrichment factor of heavy metalsshowed moderately enriched Cu, Cd, Zn, and Pb. The study clearly indicates that wet and dry depositions varied asfunction of sampling sites, seasons and distance from coal based thermal power plant.
