The results showed that H + and Cu 2+ had significant influence on the activities of four enzymes and the ability of their inhibiting followed the order: H +>Cu 2+ . Al 3+ and atrazine only had litter effects on the activity of urease and phosphatase, respectively. Furthermore, interaction analysis revealed that Cu 2+ -H + affected on the activity of acid phosphatase significantly and antagonism on invertin and urease, Cu 2+ -atrazine only exhibited the synergism on the activity of acid phosphatase. But atrazine-H + had non-interaction within the investigated concentration range. Among four enzymes, acid phosphatase was the most sensitive one to the contaminations.展开更多
