title: Sampling for formaldehyde in workplace and ambient air environments--additional laboratory validation and field verification of a passive air monitoring device compared with conventional sampling methods.
abstract: Results of three extensive plant field tests using both area and personal sampling and involving 51 sets of comparison samples show the Du Pont Pro-Tek Formaldehyde Badge to have excellent correlation with three commonly used formaldehyde monitoring methods. In addition, comprehensive laboratory validation tests are reported which confirm an overall accuracy of +/- 9.6 to +/- 11.6% for the badge over an exposure range of 0.12-6.8 ppm. Laboratory test data are also included showing that the badge: (1) meets NIOSH and OSHA accuracy requirements of less than or equal to +/- 25% down to 1.6 ppm-hours (200 ppb) for an 8-hour TWA exposure; (2) is capable of accurately sampling for 15-minute exposures; and (3) is not affected by pressure or relative humidity variations.
