A badge-type sampler for measurement of personal exposures to nitrogen dioxide in ambient air was developed. An absorbent filter containing triethanolamine solution absorbed nitrogen dioxide which diffused through layers of hydrophobic fiber filters. The wind effect on absorption rate was suppressed by the layers of these filters. It could determine the level of nitrogen dioxide of several ten ppb by exposure of several hours. The accuracy was within 20%. It was small (5×4×1 cm<SUP>3</SUP>), light (15g) and simple in structure. It could be applied without disturbing the motion of the subject person.
