Masses of individual polychlorinated biphenyl congeners in gas phases in air in Chicago, Il, USA in 2009

We report the levels of airborne individual PCB concentrations of gas phases from the City of Chicago in 2009. Twenty-seven locations were sampled for gas phases, where 141 gas phases were collected. One hundred and seventy-one individual or coeluting congener PCBs are reported. This dataset includes the sample mass for all 171 individual congeners for gas (XAD-2) phases, the deployment time and sampling flow.
