Assessing Cancer Risk Associated with Aquatic Polycyclic Aromatic Hydrocarbon Pollution Reveals Dietary Routes of Exposure and Vulnerable Populations

Figure 3

PAH mixture exposure varies in the human population depending on source: (a) chemical fate modeling of PAHs in the environment from emission source to environmental compartment to human intake route, as utilized in the USEtox model; (b) USEtox database distribution of human intake of a mixture of 7 PAH COCs. Human intake is measured by inhalation, drinking water, produce, meat and dairy, or fish, depending on the environmental compartment into which the PAH is emitted; (c) cancer cases and (d) daily adjusted life year (DALY) per kg emitted into different environmental compartments for a PAH mixture containing the seven Superfund site sediment contaminants of concern.
