  • Summary: Under the conditions of these 2-year and lifetime inhalation studies, there was no evidence of carcinogenic activity of ozone in male or female F344/N rats exposed to 0.12, 0.5, or 1.0 ppm. There was equivocal evidence of carcinogenic activity of ozone in male B6C3F1 mice based on increased incidences of alveolar/bronchiolar adenoma or carcinoma. There was some evidence of carcinogenic activity of ozone in female B6C3F1 mice based on increased incidences of alveolar/bronchiolar adenoma or carcinoma.; There was no evidence that exposure to 0.5 ppm ozone enhanced the incidence of NNK-induced pulmonary neoplasms in male rats.; Exposure of male and female rats to ozone for 2 years or 125 weeks was associated with goblet cell hyperplasia and squamous metaplasia in the nose, squamous metaplasia in the larynx, and metaplasia (extension of bronchial epithelium into the centriacinar alveolar ducts) and interstitial fibrosis in the lung.

  • Health Effects: At acute levels, ozone is an irritant and lachrymator. At chronically low doses (~40 nmol/mol) there is a great deal of evidence to show that ground level ozone can harm lung function and irritate the respiratory system. Long-term exposure to ozone and the pollutants that produce it is linked to premature death, asthma, bronchitis, heart attacks and other cardiopulmonary problems. Long-term exposure to ozone has been shown to increase risk of death from respiratory illness. An 18-year study on 450,000 people in the US revealed that those living in cities with high ozone levels such as Houston or Los Angeles had an over 30% increased risk of dying from lung disease. Both acute and chronic exposures to ozone can negatively impact the barrier function of the lung, and these exposures can initiate an inflammatory response from the immune system. This immune response involves the release of biologically active mediators that can have adverse effects on the lung tissue itself. Some effects may include the thickening of the air-blood barrier in the lungs, thus reducing the diffusion of oxygen into the blood. Animals exposed to ozone produce and release high amounts of a sugar known as hya Source: Toxin and Toxin Target Database (T3DB)
  • Toxicity Summary: Ozone is a strong oxidant and reacts directly with organic double bonds. When ozone breaks down to dioxygen it gives rise to oxygen free radicals, which are highly reactive and capable of damaging many organic molecules. Moreover, it is believed that the powerful oxidizing properties of ozone may be a contributing factor of inflammation. When inhaled, ozone reacts with compounds lining the lungs to form specific, cholesterol-derived metabolites that are thought to facilitate the build-up and pathogenesis of atherosclerotic plaques. These metabolites have been confirmed as naturally occurring in human atherosclerotic arteries and are categorized into a class of secosterols termed atheronals, generated by ozonolysis of cholesterol's double bond to form a 5,6 secosterol. Ozone has also been shown to form the suspected carcinogen bromate when it is introduced to source water with high bromide concentrations. Studies have also demonstrated an increase in collagen, a structural protein involved in fibrosis, following prolonged ozone exposure. Acute and short-term exposure studies have demonstrated ozone’s effects on lung lipids which include an increase in arachidonic acid (a pro-inflamm Source: Toxin and Toxin Target Database (T3DB)
  • Environmental Fate: A photochemical model was used to quantify the sensitivity of the tropospheric oxidants ozone (O3) and OH to changes in methane (CH4), carbon monoxide (CO), and NO emissions and to perturbations in climate and stratospheric chemistry. Coefficients of the form delta ln[O3]/delta ln[X] and delta ln[OH]/delta ln[X], where [X]= flux of CH4, CO, NO, stratospheric O3, and H2O have been calculated for a number of chemically coherent regions (e.g. nonpolluted continental, nonpolluted marine, urban) at low and middle latitudes. Sensitivities in O3 and OH vary with regional emissions patterns and are nonlinear within a given region as [X] changes. In most cases incr CH4 an CO emissions will suppress OH (neg coefficients) in incr O3 (pos coefficients) except in areas where NO and O3 influenced by pollution are sufficient to incr OH. Stratospheric O3 depletion will tend to decr O3 (except in high NOx areas) and incr OH through enhanced UV photolysis. Incr levels of water vapor (one possible outcome of a global warming) will also decr O3 and incr OH. In most regions, NO, CO and CH4 emission incr will suppress OH and incr O3, but these trends may be opposed by stratospheric O3 depletion and clim Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: Ozone concn above 80 ppb are common in the East U.S. in spring and summer, but they are unusual in the West, and ozone shows considerably more day-to-day variability in the East. Variations in ozone levels are highly correlated over distances of several hundred kilometers in the East, indicating that high values are associated with episodes of large spatial scale, > 600,000 sq km. There were 10 and 7 such episodes in 1978 and 1979, respectively, between the mo of Apr and Sept; they persisted for 3-4 days, on avg, with a range of 2-8 days, and were most common in Jun. Daily max ozone values exceeded 90 ppb at over half the sites during these episodes and were often > 120 ppb at one or more sites. An analysis of the meteorology for each episode shows that they occurred preferentially in the presence of weak, slow-moving, and persistent high-pressure systems. Two episodes that occurred outside the summer half of the yr were associated with unseasonably warm weather; only 1 episode, in Mar 1978, appeared to reflect a major stratospheric intrusion. Concn of NOx at rural locations in the East are frequently high enough (> 1 ppb) to permit significant photochemical formation of ozone. It Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: Measurements from the eastern north Pacific stratocumulus regime have been used to study components of the regional ozone budget. The surface destruction rate was determined by eddy correlation of ozone and vertical velocity measured during 8 flights of a low flying aircraft. Significant variability (2580 to 6460 s/m) was found in the measured surface resistance; it was partially correlated with friction velocity but appears to have other controlling influences as well. The mean resistance was 4190 + or - 840 s/m, which is higher (slower destruction) than most previous estimates for seawater. Flux and mean measurements throughout the marine boundary layer were used to estimate the net rate of in-situ photochemical production/destruction of ozone. Averaged over the flights, ozone concn was found to be near steady state, and a net photochemical destruction of 0.02 to 0.07 ng/cu m/sec was diagnosed. Ozone vertical distributions above the boundary layer showed a strongly layered structure with very sharp gradients. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: The results from a two dimensional model were analyzed to determine the principal modes of balance for ozone (O3) concn in different regions of the stratosphere. The analysis showed that except near the poles, O3 is in photochemical equilibrium above 35 km. In the lower stratosphere, equatorward of 50 degrees, concn of O3 is neither photochemically controlled nor transport controlled, but is set by a balance between transport and chemical processes. The low abundance of O3 in the tropics is a result of the balance between photochemical production and transport out of the region. The seasonal behavior at high latitudes, as evident from the springtime maxima, results from a balance between photochemical removal and transport into the region.
