Figure 5: ET50 (95% CI) values for exposures and re-exposures. The upper panel shows the ET50 value for each PEITC exposure (green diamond) and re-exposure (green circle). The lower panel shows ET50 value for each wash water exposure (blue diamond) and re-exposure (blue circle). Re-exposures are linked to the initial exposure by a solid line. Horizontal bars show the 95% upper and lower confidence intervals. Mean ET50 (±SE) value for the initial exposures is shown as a solid black line.
