Intracellular pH^a in controls and in treated cells (mean ± SD).

Exposure	4 hb	24 hb
Control	7.5 ± 0.11	7.5 ± 0.08
BPA	7.5 ± 0.28	7.5 ± 0.11
KBrO3	6.8 ± 0.11*	7.8 ± 0.26
BPA + KBrO3	7.2 ± 0.08†	7.0 ± 0.14*†
aIntracellular pH was quantified by flow cytometry using pHRodo®. bSamples treated with 150 μM BPA only were exposed for 5 or 25 hr; those treated with 20 mM KBrO3 only were exposed for 1 hr, then medium was replaced for 3 or 23 hr; and co-exposed samples were exposed to 150 μM BPA for 1 hr, then to 150 μM BPA + 20 mM KBrO3 for 1 hr, followed by exposure to 150 μM BPA only for 3 or 23 hr. *p < 0.05 compared with untreated controls. †p < 0.05 compared with KBrO3 alone.
