Abstract

In this artical, we chose three key heavy mental pollutants from all kinds of pharmaceutical wastewaters: zinc, cadmium and mercury to study their effects on three antioxidant enzymes of Paramecium caudatum: Superoxide dismutase (SOD), Peroxidase (POD), Catalase (CAT). Results show that three pollutants can cause activity of three antioxidant enzymes significant changing. But the trends of POD are different from that of SOD and CAT. This result shows that there maybe a different protect mechanism between CAT, SOD and POD.
