“…Finally, this work focuses exclusively on the O3 impacts on crop yields. Future work is planned to explore the combined effects of O3 and climate change impacts, due to changing temperature or precipitation, and carbon fertilization effects (Ainsworth et al, 2012;Guarin et al, 2019;Reilly et al, 2007;Tai et al, 2014). This combined approach could provide a more holistic perspective of the potential crop damages.…”

“…Among all air pollutants, ozone and particulate matter were of concern due to their negative effects on terrestrial ecosystems. Research by Guarin et al showed that about 90% of the European urban population was currently exposed to high levels of ozone pollution (Guarin et al 2019 ). In 2018, ozone concentrations in 14 of 36 European countries exceeded the WHO threshold more than 25 times per year, with 87% of monitoring stations monitoring ozone values that exceeded long-term target thresholds set by European authorities.…”

In the twenty-first century, exposure to air pollution has become a threat to human health worldwide due to industrial development. Timely, comprehensive, and reliable assessment and prediction of disease burden can help mitigate the health hazards of air pollution. This study conducted a two-stage analysis. First, we reported the air pollution–related disease burden globally and for different subgroups like socio-demographic index (SDI), sex, and age. We analyzed the trend of the disease burden from 1990 to 2019. In addition, we explored whether and how some national indicators modified the disease burden. Second, we predicted the number and the age-standardized rates of death and disability-adjusted life years (DALYs) attributable to air pollution from 2020 to 2044 by the autoregressive integrated moving average (ARIMA) model and exponential smoothing model. The age-period-cohort (APC) model in the maximum likelihood framework and the Bayesian APC model integrated nested Laplace approximations (INLAs) were further applied to perform sensitivity analysis. In 2019, air pollution accounted for 11.62% of death and 0.84% of DALY worldwide. The corresponding age-standardized rate was 85.62 (95% uncertainty interval (UI): 75.71, 96.07) and 2791.08 (95% UI: 2468.81, 3141.39) per 100,000 population. From 1990 to 2019, the number of death attributable to air pollution remained stable, and the number of DALY exhibited a downward trend. The corresponding age-standardized rates both declined. In some countries with larger population densities, higher proportions of elders, and lower proportions of females, the disease burden attributable to air pollution was lower. The predicted results showed that the number of air pollution-related death and DALY would increase. This study comprehensively assessed and predicted the air pollution–related disease burden worldwide. The results indicated that the disease burden would remain very serious in the future. Hence, some relevant policies should be developed to prevent and manage air pollution.

“…These amount to an estimated 9.9% in the Northern hemisphere and 6.2% in the Southern hemisphere, and affect developing countries disproportionately, leading to severe consequences for their food security (Mills et al, 2018a). Estimates specifically focusing on wheat yield losses in individual countries exceeded 10% in China (Feng et al, 2019) and 7–18% in Mexico depending on cultivar sensitivity (Guarin et al, 2019). In the case of India, Fischer (2019) suggested yield losses as high as 30% due to the combined effects of increasing ozone pollution and aerosols limiting the solar radiation available for plant growth.…”

Rising tropospheric ozone affects the performance of important cereal crops thus threatening global food security. In this study, genetic variation of wheat regarding its physiological and yield responses to ozone was explored by exposing a diversity panel of 150 wheat genotypes to elevated ozone and control conditions throughout the growing season. Differential responses to ozone were observed for foliar symptom formation quantified as leaf bronzing score (LBS), vegetation indices and yield components. Vegetation indices representing the carotenoid to chlorophyll pigment ratio (such as Lic2) were particularly ozone-responsive and were thus considered suitable for the non-invasive diagnosing of ozone stress. Genetic variation in ozoneresponsive traits was dissected by a genome-wide association study (GWAS). Significant marker-trait associations were identified for LBS on chromosome 5A and for vegetation indices (NDVI and Lic2) on chromosomes 6B and 6D. Analysis of linkage disequilibrium (LD) in these chromosomal regions revealed distinct LD blocks containing genes with a putative function in plant redox biology such as cytochrome P450 proteins and peroxidases. This study gives novel insight into the natural genetic variation in wheat ozone response, and lays the foundation for the molecular breeding of tolerant wheat varieties.
