Biokinetics of Hazardous Organic Chemicals in Subsoils

将研究土壤中微生物对某些易被生物降解的有机物质流入的反应。研究人员计划研究原本有机质浓度较低的土壤，以确定自然产生的微生物种群是否能够适应所选化学物质的应用，或者是否有必要接种驯化的培养物以启动降解。研究结果可为危险废物管理土壤应用系统的工程设计提供参考。

Research will be conducted on the microbial response in soils to the influx of selected organic substances that are subject to biological degradation. The investigators plan to study soils with originally low concentrations of organic matter to determine whether naturally occurring populations of micro-organisms can adjust to the application of the selected chemical or whether inoculation with acclimated cultures is necessary to initiate degradation. Results of this research may be applicable to engineering design of soil application systems for managing hazardous wastes.
