p1 is p-value of comparison of parameter values variation in the control treatment over time, p2 is p-value of comparison of treatments at time = 0, p3 is p-value of comparison over time between treatments.
NCTRL, negative control which was given air macrobubble; PCTRL, positive control which was given air macrobubble; O2, oxygen macrobubble; O2-NB, oxygen nanobubble; O3, ozone macrobubble; O3-NB, ozone nanobubble; ORP, oxidation reduction potential; DO, oxygen.
