Paper Abstract

The inhibitory effect of Cr(VI) on soil hydrolases activity during two different periods (one and six months) was investigated, in order to obtain information on the change in heavy metal toxicity with time. Considering toxicity as the ecological dose-50% (EcD50) toxicity tended to increase over six months for cellulase Cx, protease and acid phosphates and to decrease for amylase. The average EcD50 value varied between 4450 and 1210 ppm for cellulase Cx, 5000 and 2320 ppm for protease, 3830 and 3295 ppm for acid phosphatase, 4030 and over 5000 ppm for amylase.
