Research hotspots and trends of the health effects of synergistic emission reduction of greenhouse gases and air pollutants.

CiteSpace was used to sort out the relevant literature on Web of Science and China National Knowledge Infrastructure, and analyze the research hot spots and progress in this field. The findings revealed that, first the number of published works had been steadily increasing both domestically and internationally. Particularly, after 2013, the number of published articles has been growing rapidly, with a significantly higher rate observed in international publications compared with domestic ones. Second, a robust collaborative network was established by foreign literature authors and institutions, primarily centered around major universities in the United States. The number of core research authors who had published articles in this network has reached 39%. Conversely, it appeared that the relationship between domestic authors and institutions was weaker, exhibiting a decentralized structure with multiple centers. The publications of core research authors accounted for only 8% of all domestic literature works. Third, The strong synchronicity between domestic and foreign research was indicated by the results of the visual analysis, focusing mainly on studying the health effects and burden of disease caused by environmental exposure. However, specific impact mechanisms, linkages, and risk assessment were more emphasized by foreign researches. On the other hand, influencing factors and policy benefits were paid closer attention to by domestic researches. Fourth, ranging from studying the impact of environmental exposure on health endpoints to investigating climate change co-adaptation strategies and developing complex models, foreign researches centered more on global burden and decrease of particulate matter emissions. On the other hand, Domestic researches had evolved from studying the effects of climate change and air pollution on health to exploring coordinated governance countermeasures and health risks. Currently, there was considerable interest in the potential synergistic benefits of climate change, pollution reduction, and carbon reduction on health. In the future, the identification and clarification of the spatiotemporal patterns of health issues and sensitive areas, as well as public health effects caused by climate change and air pollution will be a key focus. The construction of health risk assessment models and the development and application of early warning systems should also be put on top agenda. © 2024 Chinese Society for Environmental Sciences.
