Figure 1. Continuous measurement of COCl2 concentrations inside the exposure chambers.

Figure 1.

COCl2 gas (nominal concentrations of 20 ppm or 10 ppm flowed into the exposure chambers (volume=4.5 L) at 4.4 L/min starting at zero time. The concentration of COCl2 was monitored by a. Analytical Technology, Inc. (Collegeville, PA) A21 Gas Sampling System, F12D Gas Transmitter with Phosgene Sensor. Measurements were conducted with five mice in the chamber (dotted lines) or with empty chambers (solid lines). Measurements were repeated twice with similar results.
