A review of the Northwest region, based on areas established around pre-selected points used to identify specific release sites, followed by the application of buffers used to demonstrate distance relationships involving cases and release sites.
Documentation of Toxic Release History for given regions using a Reclassification System developed to display areal chemical-toxicity-carcinogenicity features
The use of Isolines to depict specific chemical-related Exposure Risks in NW area of Portland, Oregon. Aromatics.
The use of Isolines to depict specific chemical-related Exposure Risks in NW area of Portland, Oregon. Halogenated compounds.
Individual grid cells can have a value calculated which defines the risk of exposure for cancer, based on the chemical type and numbers, amounts and/or length of time of these releases. These values then can be converted into an isoline representation.
