Biokinetics of Hazardous Organic Chemicals in Subsoils

将研究土壤中的微生物对某些可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物浓度较低的土壤，以确定自然发生的微生物群体是否能够适应所选化学物质的应用，或者是否需要接种驯化的培养物来开始降解。本研究结果可用于危险废物治理土壤施用系统的工程设计。

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.
