In order to explore toxicity of heavy crude and light crude to Artemia,the influence of toxicity and hatch time were determined. The results showed that the effects of Artemia toxicology showed a increase trend,and the concentration of logarithmic enlarge with the increase of concentration of crude oil,the light oil to the Artemia 96 h-LC50 value of 0.013 8 mg/L,the heavy crude to the Artemia 96 h- LC50 value of 0.093 4mg/L. The Artemia 96 h lethal toxicity of light crude oil was significantly higher than that of heavy crude oil(P0.05). The eggs hatch of Artemia were greatly inhibited with heavy crude and light crude,the start incubation time increase with the increase of exposure concentration of crude oil,and the influence of light crude oil was greater for start incubation time than the heavy oil.
