A2/O工艺处理后焦化废水对玉米根尖细胞遗传稳定性的影响及其氧化损伤效应
Effect of Coking Wastewater after Treatment with A2/O Process on Hereditary Stability in Maze Root Cells and Associated Oxidative Stress
摘要
Abstract
Hydroponic experiment on maize with effluent of different volume concentrations coking wastewater was carried out. After the hydroponic experiment,the micronucleus rate of root tip. Antioxidant enzyme activities,the level of reactive oxygen species and oxidation products content of maize seedings were measured in order to explore the ecological risk of effluent and provide a theoretical basis to determine its biological monitoring indexes. The results showed that after treatment by different concentrations of effluent, the micronucleus rate of treated root tip and the content of H2O2,PCO,MDA in maize seedings increased significantly,the activities of POD and CAT increased also while the activity of SOD decreased. The results suggested that the coking wastewater contaminants are significantly reduced after treatment, but there is still certain ecological risk,this may be related with elevated levels of free radicals in plants.关键词
