Abstract

Air pollution is one of the most challenging environmental issues in the world. China has achieved remarkable success in improving air quality in last decade as a result of aggressive air pollution control policies. However, the average fine particulate matter (PM_2.5) concentration in China is still about six times of the World Health Organization (WHO) Global Air Quality Guidelines (AQG) and causing significant human health risks. Extreme emission reductions of multiple air pollutants are required for China to achieve the AQG. Here we identify the major challenges in future air quality improvement and propose corresponding control strategies. The main challenges include the persistently high health risk attributed to PM_2.5 pollution, the excessively loose air quality standards, and coordinated control of air pollution, greenhouse gases (GHGs) emissions and emerging pollutants. To further improve air quality and protect human health, a health-oriented air pollution control strategy shall be implemented by tightening the air quality standards as well as optimizing emission reduction pathways based on the health risks of various sources. In the meantime, an “one-atmosphere” concept shall be adopted to strengthen the synergistic control of air pollutants and GHGs and the control of non-combustion sources and emerging pollutants shall be enhanced.

中国空气污染控制的挑战与前景

空气污染是全球最具挑战性的环境问题之一。在过去的十年中，由于采取了积极的空气污染控制政策，中国在改善空气质量方面取得了令人瞩目的成就。然而，中国的细颗粒物（PM2.5）平均浓度仍是世界卫生组织（WHO）全球空气质量指南（AQG）的六倍左右，对人类健康造成了极大的威胁。中国需要大幅减少多种空气污染物的排放，才能达到空气质量准则。在此，我们指出了未来空气质量改善所面临的主要挑战，并提出了相应的控制策略。主要挑战包括：PM2.5 污染带来的持续高健康风险、过宽的空气质量标准，以及空气污染、温室气体排放和新兴污染物的协调控制。为进一步改善空气质量，保护人类健康，应实施以健康为导向的空气污染控制策略，收紧空气质量标准，并根据各种污染源的健康风险优化减排途径。同时，采用 "一个大气层 "的理念，加强大气污染物和温室气体的协同控制，加强非燃烧源和新兴污染物的控制。

期刊介绍： Frontiers of Environmental Science & Engineering (FESE) is an international journal for researchers interested in a wide range of environmental disciplines. The journal''s aim is to advance and disseminate knowledge in all main branches of environmental science & engineering. The journal emphasizes papers in developing fields, as well as papers showing the interaction between environmental disciplines and other disciplines. FESE is a bi-monthly journal. Its peer-reviewed contents consist of a broad blend of reviews, research papers, policy analyses, short communications, and opinions. Nonscheduled “special issue” and "hot topic", including a review article followed by a couple of related research articles, are organized to publish novel contributions and breaking results on all aspects of environmental field.
