| Abstract: | Monthly variations in dustfall concentration was studied in the city of Varanasi, India, during 1988. For dustfall samples collection, special dustfall jars were set up at three different sites at a height of approximately 20 m above the ground in and outside the city. Collected dust deposits were chemically analysed and the results are briefly discussed. A comparison was made between these sites and concluded that the maximum concentration was found at Parav and the minimum at Banaras Hindu University. In addition, water soluble and water insoluble fractions were detected in dust deposits. A seasonal variation in concentrations was also observed. |
