[Effect of acid rain, copper, and atrazine on soil hydrolase activity].
The effects of acid rain, Cu2+ and atrazine on the activities of soil urease, invertase and acid phosphatase were studied by means of orthogonal test. The results showed that the inhibition rate was H+ > Cu2+, and atrazine had no significant influence on urease and intertase. Interaction analysis revealed that Cu x atrazine exhibited synergism on soil acid phosphatase activity, Cu x H had antagonism on soil invertase and urease, but atrazine x H had no interaction within the investigated concentration range. Among the three enzymes, soil acid phosphatase was the most sensitive one to the contaminations.
