The color response of several commercially available detector papers for hydrazine and nitrogen dioxide was determined in order to evaluate their usefulness as personal dosimeters which could give an estimate of the concentration-time product (CT) of an exposure. The Bug-it H25B Hydrazine Detector gave satisfactory results in the CT range of toxicological interest. Appropriate color standards should be prepared and a reusable holder for the detector strips manufactured. The Bug-it H30A Nitrogen Dioxide Detector was satisfactory as a detector for low concentrations of nitrogen dioxide but did not give colors which darkened enough to permit a quantitative estimate of the CT product to which the strips were exposed. Melpar Nitrogen Dioxide Detector Tapes were also satisfactory as a detector for low concentrations of nitrogen dioxide; but since the color developed did not darken at all with increasing exposure time, it was not possible to estimate the CT product of an exposure with this detector.
