Dataset Details

Superfund Research Program

Title: Dataset for airborne PCBs and OH-PCBs inside and outside urban and rural U.S. schools

Accession Number: doi:10.25820/data.002114

Repository: Iowa Research Online

Data Type(s): Environmental Science Data

Summary: This dataset from the Iowa Superfund Research Program (ISRP) includes indoor and outdoor air mass, concentration, and associated quality control of PCBs and OH-PCBs in two rural schools and four urban schools, the latter near a PCB-contaminated waterway of Lake Michigan in the United States. Samples (n=108) were collected as indoor/outdoor pairs using PUF-PAS from January 2012 to November 2015. Samples were analyzed using GC/MS-MS for all 209 PCBs and 72 OH-PCBs. Concentrations inside schools were 1-2 orders of magnitude higher than outdoors and ranged from 0.5 to 194 ng/m3 (PCBs) and from 4 to 665 pg/m3 (OH-PCBs). Congener profiles were similar within each sampling location across season but different between schools and indicated the sources as Aroclors from building materials and individual PCBs associated with modern pigment.
