Substantially underestimated global health risks of current ozone pollution

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: Jan. 2, 2025

Existing assessments might have underappreciated ozone-related health impacts worldwide. Here our study assesses current global ozone pollution using the high-resolution (0.05°) estimation from a geo-ensemble learning model, with key focuses on population exposure and all-cause mortality burden. Our model demonstrates strong performance, achieving mean bias of less than -1.5 parts per billion against in-situ measurements. We estimate that 66.2% is exposed to excess for short term (> 30 days year), 94.2% suffers long-term exposure. Furthermore, severe levels are observed in Cropland areas, particularly over Asia. Importantly, ozone-attributable deaths significantly surpass previous recognition specific diseases Notably, mid-latitude Asia (30°N) western United States show high burden, contributing substantially deaths. highlights significant risks may benefit ozone-exposed future. This reveals O₃-related risks, model.

Loss of life expectancy attributed to long-term ozone exposure in Chinese older adults: Cross-cohort analysis from 3 national cohorts

Journal of Advanced Research, Journal Year: 2025, Volume and Issue: unknown

Cohort evidence linking ozone (O3) exposure with mortality was sparsely investigated among the elderly in low- and middle-income countries. This study aims to quantify risk burden attributed chronic O3 Chinese older adults. A total of 30,874 adults aged ≥ 65 years were recruited from 3 national dynamic cohorts across 29 provincial regions China, 2005-2018. Annual warm-season (April-September) year-round PM2.5 concentrations estimated through well-validated satellite-based spatiotemporal models assigned participants for each survey year. Time-dependent Fragility Cox random intercept cohort employed O3-mortality association, adjusting demographic, behavioral, health, environmental covariates. counterfactual causal framework used assessment O3-attributable premature deaths based on exposure-response relationship derived multi-cohort two-pollutant analysis (+PM2.5). Years life lost loss expectancy subsequently evaluated estimation model by incorporating comparative method reference tables. 16,939 death events occurred during 0.16 million person-years follow-up surveys.

Synergistic Evolution of PM2.5 and O3 Concentrations: Evidence from Environmental Kuznets Curve Tests in the Yellow River Basin

Sustainability, Journal Year: 2024, Volume and Issue: 16(11), P. 4744 - 4744

Published: June 2, 2024

Air pollution, especially the synergistic pollution of PM2.5 and O3, poses a severe threat to human life production. The formation mechanism O3 is relatively confirmed, while research on their spatiotemporal synergy urgent. Based remotely sensed interpretation data from 90 cities in Yellow River Basin, we analyzed evolution concentrations during 2013–2020. Combined with environmental Kuznets curve, performed factor analysis using panel regression model. pattern shows gradual decrease concentration increase concentration. There strong spatial auto-correlation two pollutants’ concentrations. relationship between economy an “N-shaped” that economic development presents inverse curve. curve deterioration takes place later than mitigation pollution. Various factors have obvious heterogeneous effects Meanwhile, sensitivity effect per capita GDP midstream region stronger upstream region, strongest downstream region.
