硝基芳香化合物的植物作用研究进展OA北大核心CSCDCSTPCD

Nitro-aromatic compounds is one of the difficult biodegradable pollutants in the environment, due to its wide range of uses, large amounts of residues in the soil, water and atmosphere, caused increasingly serious environmental pollution. The pollutants can be absorbed or accumulated by various plants, as well as a metabolic degradation, using the vegetation to control its environmental pollution is an effective method. This paper reviewed recent studies nitro-aromatic compounds in plants, the uptake, transport and metabolism progress by plant are described, and the uptake and metabolism mechanism as well as effects of absorption;Nitro-arom-atic compounds physical and chemical properties, concentration and plant characteristics, in addition to other external conditions will affect the absorption of the plant, the plants decompose these compounds through the degradation of plants, joint metabolism in vitro, enzyme catalysis mechanism release by roots. Most of researches regarding the mechanism of nitro-aromatic compounds into the plant cell membrane are lack of in-depth understanding while the application of simulation model is lack of strong data for validation;environmental characteristics of enzymes and compounds involved in the reaction system mechanisms is still not clear, otherwise the reaction products, the feasibility of phytoremediation is lack of strong evidence too. In the future, we will make a further explore in the construction of model predictions, the depth of degradation mechanism research and practical application of the restoration project, forming a unified cognition, which will provide a theoretical basis for nitro-aromatic compounds contaminated soil and agricultural ecological risk assessment, and the phytoremediation.
