We report the levels of airborne individual PCB concentrations of particle phases from the City of Chicago in 2009. One hundred and seventy-one individual or coeluting congener PCBs are reported. Field blank masses for all 171 individual congeners for particle (QFF) phases are included here. The QFF blank samples were not exposed or opened to the air at any time during the sampling period.
