Jahn Paru dans : Public Health Forum, Volume 20, Issue 2, June 2012, Pages 27.e1-27.e4 Public Health und Stadtentwicklung Summary Chinese megacities pass through rapid change, coined by fast economical and population growth. This leads to impaired governability and the necessary infrastructural measures, to protect the environment, cannot keep up with this developments. This results in substantial health threatening pollution. Existing laws and regulations should be implemented of all governmental levels from the central government down to the city sub-district level to improve urban health.

[ScienceDirect, via Biblio-SHS] Auteur : Shuxiao Wang, Jiming Hao Paru dans : Journal of Environmental Sciences, Volume 24, Issue 1, January 2012, Pages 2-13 Abstract This article analyzed the control progress and current status of air quality, identified the major air pollution issues and challenges in future, proposed the long-term air pollution control targets, and suggested the options for better air quality in China. With the continuing growth of economy in the next 10-15 years, China will face a more severe situation of energy consumption, electricity generation and vehicle population leading to increase in multiple pollutant emissions. Controlling regional air pollution especially fine particles and ozone, as well as lowering carbon emissions from fossil fuel consumption will be a big challenge for the country. To protect public health and the eco-system, the ambient air quality in all Chinese cities shall attain the national ambient air quality standards (NAAQS) and ambient air quality guideline values set by the World Health Organization (WHO). To achieve the air quality targets, the emissions of SO2, NOx, PM10, and volatile organic compounds (VOC) should decrease by 60%, 40%, 50%, and 40%, respectively, on the basis of that in 2005. A comprehensive control policy focusing on multiple pollutants and emission sources at both the local and regional levels was proposed to mitigate the regional air pollution issue in China. The options include development of clean energy resources, promotion of clean and efficient coal use, enhancement of vehicle pollution control, implementation of synchronous control of multiple pollutants including SO2, NOx, VOC, and PM emissions, joint prevention and control of regional air pollution, and application of climate friendly air pollution control measures.
