CO_2CO2
1.Batch incubation experiments in aid of anaerobic incubation flask were conducted to study the anaerobic degradation and volatilization of hexachlorobenzene(HCB),the change of pH in soil,the emission of CH_4 and CO_2,and the volatilization of HCB in the Hydragric Acrisol and Gleyi-Stagnic Anthrosol added with acetic acid,glucose and citric acid.结果表明,8周内红壤性水稻土中HCB减少了约20%~44%,加入乙酸抑制HCB的降解,表明低pH条件不利于脱氯反应,加入葡萄糖和柠檬酸在前期抑制后期则促进HCB的降解;乌栅土中HCB减少了约21%~23%,加入小分子有机质对其降解没有明显的效果;六氯苯降解的主要产物为五氯苯(PCB),最终检测到红壤性水稻土中PCB为23~96μg/kg,乌栅土中为64~92μg/kg;HCB的降解与CH4和CO2的释放量在统计学上没有显著的相关性;2种土壤中,外加小分子有机碳均减少了HCB的挥发作用,且红壤性水稻土中HCB的挥发比乌栅土中更强,表明土壤有机质是影响HCB挥发的重要因子。
