    Ozone causes short-term autonomic imbalance leading to changes in heart rate and reduction in heart rate variability; [89] and high levels exposure for as little as one-hour results in a supraventricular arrhythmia in the elderly, [90] both increase the risk of premature death and stroke. Ozone may also lead to vasoconstriction resulting in ...

    (rate of reaction 2) = (rate of reaction 1) = (rate of reaction 4) Thus, ozone is mainly removed by ozone conversion. Both ozone creation and conversion depend linearly on oxygen atom concentration, but in ozone creation an oxygen atom must encounter an oxygen molecule and another air molecule (typically nitrogen) simultaneously, while in ozone ...
