Abstract
Polyurethane foam has been evaluated for use in a high-volume air sampler to collect a broad spectrum of pesticides, polychlorinated biphenyls (PCBs) and polychlorinated naphthalenes (PCNs). The sampler draws air through a glass module equipped with a particulate filter and a polyurethane foam vapor trap at flow rates which can be controlled from 100 to 250 L/min. Up to 300 cu m of air can be sampled in a 24-hour day, providing theoretical detection limits of less than 0.1 ng/cu m for some individual compounds. Extraction and clean-up methodology for gas chromatographic analysis are uncomplicated. Collection efficiencies have been determined for several organochlorine and organophosphate pesticides, PCBs and PCNs. (Copyright (c) 1977 by the American Chemical Society.)
