Case-by-Case Analyses

One end result of this project is to see how the information developed spatially about chemical release sites relates to cases. Returning to the Benzene Theory for cancer we can map several types of cancer in relation to the chemical sites to determine if any spatial relationship is demonstrated visually as well as mathematically. The following maps were produced as a part of this query.

The relationship of aromatic and non-aromatic compounds in relation to Childhood Leukemia cases

The relationship of aromatic and non-aromatic compounds in relation to Childhood Leukemia cases

Childhood Leukemia in relation to potential exposure sites for aromatic and non-aromatic halogens release.

Dioxin and Polychlorinated Biphenyls (PCB) exposure

Dioxin and Polychlorinated Biphenyls (PCB) exposure

Other chemical groups were tested spatially for relationships to Childhood Leukemia: Superfund and Superfund Applicants Sites; sites with more than 50 years of industrial and/or chemical storage/release history; 22 High Risk non-superfund, non-applicants sites; dioxin-pcb sites; free radical producer releasing sites.

Acute and chronic forms of leukemia, non-hodgkins’s lymphoma and hodgkin’s lymphoma underwent a similar spatial analysis.
