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

Figure 1

Indirect PAH exposure drives sediment-based cancer risk at the Superfund site. (a) Schematic calculation design of the original Superfund site cancer risk assessment due to sediment exposure, whereas our assessment does not take into account indirect oral exposure. Also includes the seven PAH contaminants of concern in sediment utilized for the cancer risk assessment, both AWI and our assessment. (b) Total cancer risk calculated in the original AWI risk assessment at the Superfund site due to sediment exposure, with the percentage of that cancer risk due to PAH or other contaminant exposure. Cancer risk due to Superfund site sediment exposure as calculated in the original AWI Superfund site risk assessment (c) and as calculated in our direct exposure assessment (d) in this experiment.
