Description:
A monitoring program was conducted to determine PCB levels in ambient air on and in the vicinity of three landfills in the Bloomington, Indiana area. Fixed-height measurements were made at locations on the sites where capacitors containing PCB were exposed (hot spots) and at nominally upwind and downwind locations. Vertical PCB concentration profiles were also obtained at five elevations (2 to 180 cm) above selected hot spots. Sampling was performed over 8-hour daytime periods (approximately 0900-1700 hours) and over 24-hour periods at various on- and off-site locations. Polyurethane foam (PUF) cartridges used either with Du Pont personal-type sampling pumps or EPA-developed high volume samplers were used for collection of PCB from the ambient air. The quantity of PCB (as Aroclor 1242) in the PUF cartridges was determined by extraction and analysis of the extract by electron-capture gas chromatography (EPA Method 608). Meteorological conditions were also measured at the sites during the field monitoring period.
