In cooperation with U.S. EPA, two school buildings in the City of New York with indoor air PCB concentrations expected to be >50 ng/m3 were selected for the PAAS study. The 6-day sampling event occurred during September 2016 when school was not in session. Active air samples were collected using a low-volume SKC AirChek® XR-5000 personal sampling pump equipped with a glass cylinder containing polyurethane foam (PUF) sorbent for the collection of PCBs in accordance with EPA Method TO-10A. Tisch Environmental Model TE-200-PAS Passive Air Samplers with PUF disks were utilized for passive air sampling. Results from the 26 active and 10 passive air samples analyzed for 209 PCB congeners using USEPA Method 1668A are presented in a table. http://www.dioxin2017.org/uploadfiles/others/9701_0515154246.pdf
