摘要：The present study is an effort to investigate physical and chemical parameters like pH, conductivity andconcentration of Ca, Mg, Cu, Cd, Pb, Zn, Fe in samples of wet precipitation in order to evaluate the influence of themain anthropogenic sources in Kota city at various sampling sites situated in five zones while considering Kota SuperThermal Power Station as point source. A total of 90 event-based wet precipitation samples were collected fromJanuary to December, 2011. Samples were analyzed for concentrations of Fe, Zn, Cu, Cd, Mg and Pb using AtomicAbsorption Spectrophotometer (Shimadzu-6300). Ca has been determined using Flame Photometer (Systronics -128).The average pH at these zones varied from 6.54 to 7.44, covering all samples having alkaline range. On the basis ofenrichment factor, Pearson correlation coefficient and principal component analysis, it is concluded that Ca, Mg and Feare originated from a common source that is soil while prime source of Cu, Cd and Zn is combustion products at KotaSuper Thermal Power Station. A significant EF value of Pb in the studied zones indicated its anthropogenic origin.
