ABSTRACT

 

Forty soil samples from 15 cm. depth were collected during Nov. 2009 from the surroundings of Hirmi cement plant, Raipur district (India). Chemical analysis of these samples indicated that due to effect of cement dust pollution the soil properties like pH, electrical conductivity, calcium carbonate content increased significantly. Similarly the content of potassium, calcium and magnesium increased in the vicinity of the cement plant. The cation exchange capacity of the soil also increased from 40.5 to 50.2 meq 100 g-1soil at 5000 m and 50 m distance respectively. The content of heavy metal like lead and cadmium increased from 2.08 and 0.030 mg kg-1 at 5000 m to 3.63 and 0.055 mg kg-1 soil at 50 m distance respectively. On the other hand the phosphorus content significantly decreases from 17.1 kg ha-1 at 5000 m to 11.3 kg ha-1 at 50 m distance. Whereas the content of other major and micronutrients like nitrogen, copper, zinc, iron, manganese and boron observed decreasing trend but the results were statistically non significant. Increasing effect of cement dust was found significant up to a distance of 1000 m in case of soil pH, electrical conductivity, CaCO3 content, cation exchange capacity of soil, content of potassium, calcium, magnesium and accumulation of lead and cadmium in soil. The effect further extended up to 2000 m in case of CaCO3, potassium, calcium, magnesium, lead and cadmium content. On the other hand the effect in terms of decrease was significant up to 1000m in case of available phosphorus content in soil.
