Figure 5.

Effects of Cl₂ on blood pressure. Rats were acclimatized to tail-cuff blood pressure measurement protocols and then exposed to air (open squares) or Cl₂ (closed squares; 400 ppm, 30 min), and blood pressure measured again at 24 and 48 hours thereafter. −48 h and −24 h indicate measurements during acclimatization and indicate stable blood pressures before Cl₂ exposure. Time 0 indicates measurements (30–60 min before Cl₂ exposure). No significant differences between mean arterial blood pressure (MAP) as a function of time in air or Cl₂ groups (by one-way ANOVA) or between groups (by two-way repeated measures ANOVA) were observed. Data are mean ± SEM (n = 2–4).
