title: Field comparison of two methods for the determination of NO2 concentration in air.
abstract: A field test of two sampling methods for the determination of NO2 concentration in air is reported. All samples were collected in an underground salt mine in which diesel equipment is operated. Although each method has it own advantage, both appear to be suitable for most industrial hygiene applications.
