Analysis of Soil and House Dust for Polycyclic Aromatic Hydrocarbons

摘要

It has been conjectured that jet turbine exhaust near airplane flight paths mayresult in significant human exposure to Polycyclic Aromatic Hydrocarbons (PAHs). The EPA Risk Reduction Engineering Laboratory (RREL) arranged access to a household located approximately eight miles from the end of a runway at the Greater Cincinnati and Northern Kentucky Airport, and collected soil, wipe, and dust samples in and around the household. A total of 19 PAH ranging from naphthalene (2-ring) to coronene (7-ring) were measured. The general concentration trend for the 19 PAH is house dust > entryway dust > soil. The house dust samples were colleted inside the household and the entryway dust and soil samples were collected outside. Seven of the target PAH are ranked as probable human carcinogens (B2) in the U.S. EPA's Integrated Risk Information System. The concentrations of B2 PAH account for roughly half of the concentrations of the sums of 19 PAH in most soil and dust samples but not in wipe samples.
