Graph theoretical toolchain. These steps were undertaken to assess exposure impact of multiple chemical and non-chemical environmental exposures on lung cancer mortality and mortality disparities using a public health exposome approach. Date from diverse sources were collected, curated and prepared for further interrogation. Modern combinatorial tools were used to distill highly correlated subgraphs for more traditional statistical analysis. These results can be used by domain scientists within community settings to generate and test hypotheses and to translate findings into public and environmental health policy and practice. The first four operations performed in this paper were used to demonstrate the proof of concept of the public health exposome approach while the latter two were designed to motive action
