Effect of Brick Kiln Emission on Soil Enzyme Activity

Abstract

Brick kiln emissions contain toxic heavy metals which pose serious threats to soil enzyme activity. Present study was conducted for the evaluation of effect of brick kiln on four soil enzyme activity (dehydrogenase, phosphatase, urease and arylsulfatase). The selected brick kiln was situated in Sulindabad village of Saharsa district. Enzyme activity was tested as a distance of 100m, 200m, 300m, 400m and 500m away from brick kiln. For control, enzyme activity was tested in soil samples collected 1km away from brick kiln. The enzyme activity was lowest at a distance of 100m away from the brick kiln and remain poor up to 500m away from brick kiln.
