Summary Maize (Zea mays L.) for the tested plants, meadow brown soil as the soil tested in order to microsomal cytochrome P450 content, superoxide dismutase (SOD), catalase (CAT) and peroxidase enzyme (POD) activity of indicators, the soil phenanthrene and pyrene in response to exposure to eco-toxicological studies. The results show that phenanthrene, pyrene exposure can cause detoxification of plant metabolism and antioxidant defense system of the stress response, caused varying degrees of detoxification of plant metabolism and changes in antioxidant capacity. P450 enzyme activity and low concentrations of phenanthrene and pyrene in a single - relevant exposure concentration (r = 0.834, P <0.01), and phenanthrene and pyrene exposure concentration was negatively correlated compound, saying that Ming Fei, pyrene compound exposed to lead detoxification metabolism of a reduced ability to detoxify the metabolism of plants have synergistic toxic effects; SOD activity and phenanthrene and pyrene in a single exposure concentration was negatively correlated, CAT activity and phenanthrene and pyrene in a single - exposure concentration was positively correlated, POD activity and water solubility of the Philippines positively correlated with the total concentration of pyrene in a negative correlation. SOD, CAT and POD activity and phenanthrene and pyrene were positively related to the concentration of compound exposure, saying that Ming Fei, pyrene complex degree of exposure to lead to reduced oxidative damage, oxidative damage of plants with antagonistic effects .
