Figure 3
Bar plot of pulmonary 99m Tc-DTPA clearance half-time in measured units at 3 h and 22 h post-exposure. Black bars show estimated mean ± SEM at 0 μg/m3 of CA exposure and striped bars at 100 μg/m3 of CAFP exposure. Asterisk indicates significant difference between CA and CAFP exposures (6.3% increase per 100 μg/m3, p = 0.026).
