| 摘 要： | 通过盆栽实验,测定在低浓度石油烃浓度下翅碱蓬的生长生理指标及沉积物和翅碱蓬中石油烃含量的变化,研究石油烃对翅碱蓬生理特性和抗氧化酶系统的影响及植物-微生物联合修复效果。结果表明,翅碱蓬抗氧化酶能够快速提高活性来抵御逆境,植株还可通过增加其叶绿素含量等来适应或补偿逆境造成的损失。同时还发现,当植物处于石油烃污染沉积物时,它体内污染物的分布会与自然情况下有所不同,自然情况下分布为茎>叶>根,受污染时分布为根>茎>叶,该结果可以作为判断沉积物是否受到污染的依据。实验的不同处理(加植物加菌组、只加菌未种植物组、种植物未加菌组)去除率分别为70.87%、63.66%和60.26%,翅碱蓬-降解菌处理的沉积物中石油烃残留浓度最低、去除量最高,表明植物-微生物联合作用更有利于石油烃污染沉积物的修复。

| Abstract: | The pot experiment was conducted to investigate the physiological indexes of Suaeda heteroptera and biodegradation of petroleum hydrocarbon contamination in sediments. The results showed that the antioxidant enzymes of Suaeda heteroptera could improve the activity rapidly to against adversity and it could also increase its chlorophyll content in leaves to adapt or compensate for the losses. The distribution results (root>stem>leaf) also showed that the distribution of pollutants in plant was different from nature circumstance(stem>leaf>root)which could be used as a basis for determining whether the sediments had been polluted. Biodegradation rates for adding plants and bacteria group, adding bacteria group, and adding plants group were 70.87%, 63.66%, and 60.26%, respectively. Suaeda heteroptera-microbial combined remediation got the highest biodegradation. |
