Abstract

The spatial disparity of air pollutants is one of the key influential factors for environmental inequality. We quantitatively evaluated the evolution of PM_2.5 spatial disparity in China during 2013–2020, and investigated the associations between PM_2.5 spatial disparity and economic indicators. Differences in PM_2.5 between more- and less-polluted cities declined over time, suggesting decreased absolute disparity. However, the more polluted cities in 2013 remained so in 2017 and 2020, and vice versa, indicating persistent relative disparity. PM_2.5 pollution levels increased with higher GDP per capita in less-developed areas of China, but such negative effects weakened over time, while economic development tended to promote cleaner air in developed areas of China. Therefore, policies to improve air quality and promote economic development simultaneously are needed in China to reduce the disparity of air pollution and promote all people to enjoy environmental equality.

中国PM2.5污染差异的演变

大气污染物的空间差异是造成环境不平等的主要影响因素之一。我们定量评估了2013-2020年中国PM2.5空间差异的演变，并调查了PM2.5空间差距与经济指标之间的关系。随着时间的推移，污染程度较高和污染程度较低的城市之间PM2.5的差异有所下降，这表明绝对差异有所缩小。然而，2013年污染更严重的城市在2017年和2020年仍然如此，反之亦然，这表明相对差距持续存在。在中国欠发达地区，PM2.5污染水平随着人均GDP的增加而增加，但这种负面影响随着时间的推移而减弱，而经济发展往往会促进中国发达地区的空气清洁。因此，中国需要同时采取改善空气质量和促进经济发展的政策，以缩小空气污染的差距，促进所有人享有环境平等。

期刊介绍： Eco-Environment & Health (EEH) is an international and multidisciplinary peer-reviewed journal designed for publications on the frontiers of the ecology, environment and health as well as their related disciplines. EEH focuses on the concept of “One Health” to promote green and sustainable development, dealing with the interactions among ecology, environment and health, and the underlying mechanisms and interventions. Our mission is to be one of the most important flagship journals in the field of environmental health. Scopes EEH covers a variety of research areas, including but not limited to ecology and biodiversity conservation, environmental behaviors and bioprocesses of emerging contaminants, human exposure and health effects, and evaluation, management and regulation of environmental risks. The key topics of EEH include: 1) Ecology and Biodiversity Conservation Biodiversity Ecological restoration Ecological safety Protected area 2) Environmental and Biological Fate of Emerging Contaminants Environmental behaviors Environmental processes Environmental microbiology 3) Human Exposure and Health Effects Environmental toxicology Environmental epidemiology Environmental health risk Food safety 4) Evaluation, Management and Regulation of Environmental Risks Chemical safety Environmental policy Health policy Health economics Environmental remediation
