英文摘要	Methodology for application of a Geographical Information System (GIS) to the distribution of selected toxic chemicals in Lake Erie of the Great Lakes is proposed and described in detail in this paper. Seventeen different organic compounds were selected as toxic chemicals. An integrated analysis was conducted utilizing a GIS system -- SPANS. Concentration distributions for individual organic compounds were mapped in GIS by applying the spatial interpolation of point data. An overlay map of fourteen selected toxic chemicals was produced in GIS displaying an overall concentration pattern. On this overlay map different levels of toxic chemical concentrations in Lake Erie were clearly identified taking into consideration the fourteen chemicals. The results indicated that the distributions of the selected toxic chemicals displayed higher concentration primarily in the West Basin, near the Detroit River, of the lake. Polychlorobiphenyls (PCBs) and Dieldrin which come from the sediments are the predominant organic pollutants in Lake Erie. The area analysis in GIS showed that 95.60% of the total water in Lake Erie displayed moderate and low concentration of the selected toxic chemicals. This study shows that the proposed methodology for application of GIS is suitable for mapping the distribution of organic pollutants and for managing water quality in a large water body such as Lake Erie.
