The maximum levels of SPM varied between 594 μg/m^3 to 620 μg/m^3 at selected monitoring sites while the minimum levels varied between 209μg/m^3 to 220 μg/m^3. These values were observed always above the National Ambient Air Quality Standards （NAAQS） set by the State regulatory body. Major sources of SPM were identified as the industrial activity and traffic plying on the national highway. Collected SPM samples were further analyzed for the ignitable matter as loss on ignition （LOI） and organic tarry matter （OTM） content. Ignitable component of the SPM constituted about 45% and tarry matter in the ambient air was about 12%. Effects of meteorological parameters like temperature, wind direction and wind speed on SPM levels are discussed.展开更多

Sangamner city is using the River water for drinking, domestic and industrial purpose. At the same time the waste generated is discharged into the River without or with partial treatment. So in present investigation the River water quality was analyzed for the parameters like pH, Electrical Conductivity, Total Dissolved Solids, Total Hardness, Calcium, Magnesium, Alkalinity, Chloride, Dissolved Oxygen, Chemical Oxygen Demand, Biological Oxygen Demand. Sodium, Potassium, Sulphate, Phosphate and Nitrate. The water quality index for drinking purpose was calculated using same data. The grading system was used to assess the water quality index. The result indicates that the poor water quality at four sites ranging from 250 to 745. Only site 1 shows good water quality which is 36.08 which lies in grade B.展开更多
