For many years, the role of ozone (O3) against pathogens has been studied and it has been revealed that ozone can display biological effects and therapeutic index (Berson et al., 1996; Bocci, 1996; Hernandez et al., 1995; Turcic et al., 1995; Verrazzo et al., 1995; Wolfe et al., 1989). Ozone is a natural gas that is distributed at approximately 0.01–0.04 ppm (part per million) of the world’s at...

BACKGROUND The uncontrolled discharge of untreated ballast water, which is essential for a ship's optimal operation, one the major causes sea environmental pollution by shipping. Among disinfection methods available water treatment, ozonation commonly used method, but its performance limited rapid ozone auto-decomposition rate. Nanobubbles (NBs) technology has attracted much scientific interest...

Treatment of the ozone-sensitive tobacco (Nicotiana tabacum L. cv Bel W3) with an ozone pulse (150 nL L(-1) for 5 h) induced visible injury, which manifested 48 to 72 h from onset of ozone fumigation. The "classical" ozone symptoms in tobacco cv Bel W3 plants occur as sharply defined, dot-like lesions on the adaxial side of the leaf and result from the death of groups of palisade cells. We inve...

The overall objective of this study was to develop a decontamination method against microorganisms in cardamom (Elettaria cardamomum (L.) Maton) seeds using ozone as a decontaminating agent. Ozone treatment was conducted 3 times, at 24-h intervals, and the parameters of the process were determined assuring the least possible losses of biologically active substances (essential oils and polypheno...

Apple (Malus × domestica Borkh.), a popular and widely cultivated fruit world-wide, contains bioactive triterpenes and phenolic compounds with potentially valuable pharmacological functions. This thesis investigated the effects of pre-harvest and postharvest factors on concentrations of these bioactive compounds in apples. It also studied the effect of ozone treatment, before or during storage,...

plants and field-grown aspen trees (Populus tremuloides Michx.) exposed to ambient or twice-ambient ozone. Root dry weight of potted plants decreased up to 45% after 12 weeks of ozone treatment, and root system respiration decreased by 27%. The ozone-induced decrease in root system respiration of potted plants was more closely correlated with decreased root dry weight than with specific root re...

Leptin is a satiety hormone that also has proinflammatory effects, including augmentation of ozone-induced pulmonary inflammation. The purpose of this study was to determine whether reductions in endogenous levels of leptin can attenuate pulmonary responses to ozone. To reduce serum leptin, we fasted mice overnight before ozone exposure. Fasting caused a marked reduction in serum leptin to appr...
