In this paper,effect of acetanilide herbicides butachlor on Phsiological and Biochemical Characteristics of Microalgae Dunaliella salina was studied in the laboratory. The results showed that the growth of Dunaliella salina was stimulated under low concentration of butachlor culture medium and significantly inhibited under high concentration of butachlor culture medium. Butachor also had effects on the activities of photosynthetic pigment,protein content,superoxide dismutase (SOD) and peroxidase (POD) of Dunaliella salina.
