Ozone Poisoning

Ozone poisoning refers to the adverse effects of ozone gas, which is present at low altitudes as part of air pollution, and at high altitudes. Toxicity is usually the result of inhalation of the gas.


The clinical manifestations of ozone poisoning are most apparent in the respiratory system, which is the main organ to be affected. Other organs and systems are also affected, such as the eyes and the central nervous system (CNS). The detrimental effects of ozone are due to ozone molecules, as well as its byproducts, including reactive oxygen species (ROS) [1] [2]. Ozone is present in varying concentrations in both indoor and outdoor air, and exposure to significant concentrations takes place in high altitude flights.

The respiratory symptoms associated with ozone toxicity include coughing, wheezing, chest pain, shortness of breath, chest discomfort and nasal mucosal and pharyngeal irritation. The severity of symptoms and the levels of ozone at which symptoms are elicited vary between individuals. Moreover, the effects of ozone are more marked during exercise. It has been suggested that adults in their second and third decades of life are more prone to the effects of ozone, as well as overweight individuals.

Ozone decreases lung function, both on acute and chronic exposure and it has been shown that repeated exposure precipitates symptoms and worsens already existing complaints. A positive correlation between higher ozone levels and respiratory-related hospital admissions and morbidity has been observed [3]. In the general population, ozone increases the extent to which airways respond to stimuli such as histamine, induces inflammation of the airways and increases the permeability of pulmonary blood vessels resulting in leakage of plasma proteins in the lungs [4]. Individuals with asthma may suffer from more frequent acute exacerbations, as well as an increase in the severity of such events [5] [6]. Furthermore, they have a lowered tolerance towards triggers that are known to cause asthmatic attacks.

Ozone may cause eye irritation and dryness, and worsen allergic conjunctivitis. Fatigue has been noted as well, along with other neurological symptoms that include headaches and decreased concentration [7].

Compulsive Disorder
  • Disorder, constant obsessive circular thoughts – all sorts of other cognitive and emotional disturbances resulting in a very “jumpy” personality – suicidal thoughts – emotional impulsivity – depression – moodiness – not being able to understand written[thepowerofozone.com]
  • I think that the joint pain, feelings of having a veil between myself and reality (derealization or depersonalization) might have been part of lyme; or maybe it was candida.[thepowerofozone.com]


A physical exam will confirm the respiratory symptoms reported. There are several modalities that can be used to observe and measure the effects of ozone on the respiratory system, these are:

  • Bronchoscopy: This shows inflamed airways [8].
  • Bronchoalveolar lavage (BAL): This is used to acquire samples of epithelial lining fluid for biochemical analysis. It reveals the presence of neutrophils as well as several inflammatory mediators, namely cytokines, leukotrienes and other eicosanoid derivatives. There is also an increase in lactose dehydrogenase, which is an indicator of cell damage. Plasma proteins may also be present.
  • Pulmonary function tests (spirometry): These show decreased lung function in several parameters, examples of these being forced expiratory volume (FEV) and forced vital capacity (FVC) [9].

Serum levels of inflammatory molecules and white blood cells may also be elevated.


  • Usually 10 control (no prior treatment) animals and 10 treated animals were exposed together in a large glass chamber 12.5 in. 30 in. 16 in. to ozone generated by a water-cooled corona discharge type of ozonizer.[nature.com]
  • So I started doing what I believed had beaten lyme once before: ozone treatments. First I took out what I thought was the biggest hammer in my O3 arsenal: ozone IVs. Unexpectedly, I barely reacted to them.[thepowerofozone.com]

  • Here we extend UIUC's two-dimensional chemical-transport model to investigate possible effects of heterogeneous reactions of ozone on aircraft-generated carbon particles, including a treatment of soot poisoning in the model.[experts.illinois.edu]


  • One should first rule out common infectious etiologies for symptoms. Recent sick contacts, flulike or viral symptoms, any history of exposure to pulmonary mycoses, and other factors should all be considered prior to a diagnosis of NO 2 toxicity.[emedicine.medscape.com]

  • Without proper separation of the respiratory conditions with different pathophysiology, it is unknown whether the response is solely contributed by bronchitis.[insightsinchestdiseases.imedpub.com]


  • The presence of the lipid molecules is crucial for the exchange of oxygen and carbon dioxide, as they prevent the wet surfaces of the lung from collapsing.[phys.org]

  • What can I do to prevent over-exposure? Your ozone generator should not [be] pumping ozone directly into the room. If you are using an ozone generator, use it in conjunction with your ventilation system.[lorrainefrantzedwards.blogspot.com]
