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.

Presentation

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].

Entire Body System

  • Fatigue

    Adrenal Fatigue Initially thinking that adrenal fatigue was some wishy-washy pseudo-illness of professional hypochondriacs, I came across the following description : “ Morning fatigue – not feeling awake until about 10 am Afternoon fatigue – sleepiness [thepowerofozone.com]

    Fatigue has been noted as well, along with other neurological symptoms that include headaches and decreased concentration. A physical exam will confirm the respiratory symptoms reported. [symptoma.com]

    Fatigue, headache, heaviness of the head and/or change in respiratory functioning results at 1-2 ppm. An ozone level at 5-10 ppm triggers breathing difficulty, malaise and/or increased breathing rate. [ekasuga.co.jp]

    Chest X-rays were normal in 2 to 3 weeks, but 9 months later they still complained of fatigue and exertional dyspnea (labored respiration). 25.00 ppm and up Ozone concentrations that are immediately hazardous to human life are unknown but on the basis [ozoneservices.com]

    Additional symptoms include headache, blurred vision, nausea, fatigue, and vomiting. The smell of ozone is noticeable even at low levels. [disabled-world.com]

  • Malaise

    An ozone level at 5-10 ppm triggers breathing difficulty, malaise and/or increased breathing rate. [ekasuga.co.jp]

Respiratoric

  • Cough

    Acute symptoms Common signs and symptoms are as follows: Cough Light-headedness Dyspnea Chest tightness Choking Diaphoresis Loss of consciousness (at very high concentrations or in very susceptible individuals) Coughing is the most common manifestation [emedicine.medscape.com]

    The respiratory symptoms associated with ozone toxicity include coughing, wheezing, chest pain, shortness of breath, chest discomfort and nasal mucosal and pharyngeal irritation. [symptoma.com]

    Ozone at 0.4-0.5 ppm causes irritation of the upper air passage, and 0.6-0.8 ppm results in chest pain, coughing and/or decreased lung function and lung diffusing capacity. [ekasuga.co.jp]

    Breathing pain, coughing, wheezing, difficulty when exercising. Permanent lung damage. [lorrainefrantzedwards.blogspot.com]

    Symptoms of ozone exposure in healthy people include coughing, wheezing, and pain when taking a deep breath. Studies show that children don't usually report symptoms even when they have measurable decreases in lung function. [airnow.zendesk.com]

  • Dyspnea

    Suspect methemoglobinemia in patients exposed to NO 2 who exhibit cyanosis or dyspnea. The initial absence of significant symptoms does not exclude a subsequent development of serious disease. [emedicine.medscape.com]

Gastrointestinal

  • Overeating

    Prolonged exposure to high concentrations of ozone can cause severe damage to the lungs and other parts of the respiratory system, and over time may have irreversible effects. [lorrainefrantzedwards.blogspot.com]

    However, when Ozone levels approach 0.125 ppm over a 1 hour period to 0.404 ppm over an 8 hour period the air quality is very unhealthy and sensitive people will experience severe respiratory symptoms and breathing problems. [home-air-purifier-expert.com]

Neurologic

  • Headache

    Fatigue has been noted as well, along with other neurological symptoms that include headaches and decreased concentration. A physical exam will confirm the respiratory symptoms reported. [symptoma.com]

    Fatigue, headache, heaviness of the head and/or change in respiratory functioning results at 1-2 ppm. An ozone level at 5-10 ppm triggers breathing difficulty, malaise and/or increased breathing rate. [ekasuga.co.jp]

    Can cause nausea and headaches in some individuals. Extended exposure could cause lung edema (an abnormal accumulation of serous fluid in connective tissue or serous cavity). [ozoneservices.com]

    Different studies on the effects of ozone show that short term exposure to ozone will cause respiratory problems, burning sensation in the eyes, coughing headaches increased sensitivity to allergens, among other symptoms. [cambridgemask.com]

  • Confusion

    Stephens worries that the UCI study sows confusion by testing ionic air purifiers alongside ozone generators. Indeed, she points to news reports on the study that confused Sharper Image products with ozone generators. [webmd.com]

    The two are completely separate subjects, often confused. While some ionic and all electrostatic air cleaners emit ozone as a byproduct, ozonator purifiers create it by design. [air-purifier-power.com]

    So don't confuse fresh mountain air with any benefit of Ozone. [home-air-purifier-expert.com]

  • Vertigo

    Severe cases may require hospitalization and exhibit the following symptoms: dyspnea, cough, choking, tachycardia, vertigo, lowered blood pressure, cramps and chest pains. Recovery after severe acute ozone toxicity is slow. [lorrainefrantzedwards.blogspot.com]

Workup

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.
