Aerosols pollution China

Serious haze pollutions characterized high aerosols loading often affect most cities in China, due to rapid urbanization and industrialization. In response to the extremely severe haze pollution the Chinese State Council announced its aim to reduce concentrations of PM2.5 (particulate matter with an aerodynamic diameter less than 2.5 micrometers) by up to 25 per cent relative to 2012 levels by 2017. However, the factors contributing to the high levels of particulate matter present during haze pollution event remain poorly understood. Insights into the sources of the major contributor to PM is important for polices to mitigate the impact of PM on human health and climate change. Both stable (13C) and radioactive (14C) carbon isotopes will be measured on organic and elemental carbon constituents in Chinese aerosol samples.
