摘要

Exposure to ambient ozone (O-3) is a risk factor for public health and causes damage to vegetation, including agricultural crops. In this study, we performed a comprehensive estimate of the spatial distribution of premature deaths and main crop yield losses attributed to ambient O-3, across China in 2014, by applying the Global Burden of Diseases approach and AOT40 metric (i.e., above a threshold of O-3 concentration of 40 ppb). Our results show that China's total premature deaths in 2014 due to COPD attributed to O-3 exposure were 89,391 (CI95: 32,225-141,649) with spatial variation across provinces. O-3 induced production losses from all crops were 78.4 million metric tons, and the relative yield losses ranged from 8.5 to 14.0% for winter wheat, 3.9-15.0% for rice, and 2.2-5.5% for maize. The top four Chinese provinces (Sichuan, Shandong, Henan and Hunan) for premature deaths attributed to O-3 pollution also suffered severe losses in yields of winter wheat and rice. Our results provide quantitative evidence of O-3 induced impacts on both the public health and crop yields across Chinese provinces, which have important policy implications for the government to alleviate O-3 pollution in addition to PM2.5 pollution that is currently being addressed.
