Abstract

What is already known about this topic?: Fine particulate matter (PM_2.5) and ozone (O₃) are prevalent pollutants in the atmosphere, which threaten human health, especially the respiratory system. Typically, people are exposed to a mixture of various pollutants in the environment. Thus, the single and combined effects of both pollutants need to be investigated.

What is added by this report?: PM_2.5 and O₃ increase the risk of death from lung cancer, chronic obstructive pulmonary disease (COPD), and respiratory diseases, with their lagged and cumulative effects analyzed, indicating an acute effect. In addition, combined exposure to both pollutants can significantly affect disease deaths.

What are the implications for public health practice?: This study provides further evidence of the single and combined effects of PM_2.5 and O₃ on respiratory diseases, emphasizing the need for sustained efforts in air pollution control, with greater attention to the synergistic management of air pollutants.

2018-2021年中国广东省广州市PM2.5和臭氧单一及复合暴露的呼吸系统疾病死亡风险评估。

关于本专题的已知信息细颗粒物（PM2.5）和臭氧（O3）是大气中普遍存在的污染物，它们威胁着人类的健康，尤其是呼吸系统。通常，人们会接触到环境中各种污染物的混合物。因此，需要对这两种污染物的单一影响和综合影响进行研究：PM2.5和O3会增加肺癌、慢性阻塞性肺病（COPD）和呼吸系统疾病的死亡风险，对它们的滞后效应和累积效应进行了分析，表明它们具有急性效应。此外，综合暴露于这两种污染物会显著影响疾病死亡：这项研究进一步证明了 PM2.5 和 O3 对呼吸系统疾病的单一影响和综合影响，强调了在空气污染控制方面持续努力的必要性，并更加关注空气污染物的协同管理。
