Abstract

BACKGROUND: Although many studies have linked elevations in tropospheric ozone to adverse health outcomes, the effect of long-term exposure to ozone on air pollution-related mortality remains uncertain. We examined the potential contribution of exposure to ozone to the risk of death from cardiopulmonary causes and specifically to death from respiratory causes. METHODS: Data from the study cohort of the American Cancer Society Cancer Prevention Study II were correlated with air-pollution data from 96 metropolitan statistical areas in the United States. Data were analyzed from 448,850 subjects, with 118,777 deaths in an 18-year follow-up period. Data on daily maximum ozone concentrations were obtained from April 1 to September 30 for the years 1977 through 2000. Data on concentrations of fine particulate matter (particles that are < or = 2.5 microm in aerodynamic diameter [PM(2.5)]) were obtained for the years 1999 and 2000. Associations between ozone concentrations and the risk of death were evaluated with the use of standard and multilevel Cox regression models. RESULTS: In single-pollutant models, increased concentrations of either PM(2.5) or ozone were significantly associated with an increased risk of death from cardiopulmonary causes. In two-pollutant models, PM(2.5) was associated with the risk of death from cardiovascular causes, whereas ozone was associated with the risk of death from respiratory causes. The estimated relative risk of death from respiratory causes that was associated with an increment in ozone concentration of 10 ppb was 1.040 (95% confidence interval, 1.010 to 1.067). The association of ozone with the risk of death from respiratory causes was insensitive to adjustment for confounders and to the type of statistical model used. CONCLUSIONS: In this large study, we were not able to detect an effect of ozone on the risk of death from cardiovascular causes when the concentration of PM(2.5) was taken into account. We did, however, demonstrate a significant increase in the risk of death from respiratory causes in association with an increase in ozone concentration.

  • The benefit estimated by Moch et al. is inconsistent with the relative risk estimated by Jerrett and colleagues of about 1.04 (95% CI 1.01-1.07) for a 10 ppbv increase in ambient ozone.

    “This is inconsistent with the relative risk estimated by Jerrett and colleagues [73] of about 1.04 (95% CI 1.01–1.07) for a 10 ppbv increase in ambient ozone.”

    The Results report a relative risk of 1.040 (95% CI, 1.013–1.067) for each 10-ppb increase in ozone in a two-pollutant model. Those figures round to the cited values, but the estimate is specifically for death from respiratory causes, not mortality generally as the citing sentence could imply. (LLM, conf=0.87)

  • For chronic respiratory disease mortality, the applied beta is ln(1.06) per 10 ppb ozone (95% CI 1.03-1.10), derived by GBD 2019.

    “For chronic respiratory disease mortality, we apply a of ln(1.06) per 10 ppb ozone (95 % confidence interval (CI) 1.03-1.10) derived by GBD 2019 (Jerrett et al., 2009; Malashock et al., 2022; GBD 2021 Risk Factors Collaborators, 2020).”

    From Air quality impacts of stratospheric aerosol injections are likely small and mainly driven by changes in climate, not aerosol settling (2026) · cites this paper as Jerrett et al., 2009

    The Results report an association between a 10-ppb increase in ozone and mortality from respiratory causes, supporting the general relationship. But the paper reports a relative risk of 1.040 (95% CI 1.013–1.067) in its two-pollutant model, not 1.06 (95% CI 1.03–1.10); it does not identify the outcome as chronic respiratory disease mortality or derive a GBD 2019 coefficient. (LLM, conf=0.88)

  • An analysis of national databases found a positive association between increase in long-term ozone concentrations and an increased risk of respiratory diseases and death.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
