    Abstract: With the rapid development and the widely application of carbon nano-materials, they will inevitably enter our environment. In order to explore the ecological risk in the presence of both carbon nano-material and environmental organic pollutant, effect of nC60 colloids and phenanthrene on germination, seedling growth, physiological and biochemical functions of rice were examined. The results showed that nC60 itself didn't affect seeds germination, but could reduce the inhibition effect of phenanthrene; nC60 decreased the shoot length of rice seedlings, however it did not have a synergistic effect with phenanthrene. The influence of nC60 and phenanthrene on the root elongation was concerned with the concentrations of dissolved nC60 and phenanthrene. nC60 colloids could activate the antioxidase, such as superoxide dismutase(SOD), peroxidase(POD) and catalase(CAT). However it didn't cause significant oxidative damage to rice seedlings. Moreover, nC60 could dramatically compromise the oxidative damage caused by phenanthrene. Thus, plant responses in the presence of both carbon nanoparticles and organic pollutant differ from those of either pollutant significantly.
