Using size-resolved filter sampling and chemical characterization, high concentrations of
water-soluble ions, carbonaceous species and heavy metals were found in both fine (PM …

Additional size-resolved chemical information is needed before the physicochemical
characteristics and sources of airborne particles can be understood; however, this …

Extreme haze episodes repeatedly shrouded Beijing during the winter of 2012–2013,
causing major environmental and health problems. To better understand these extreme …

A single particle aerosol mass spectrometer (SPAMS) was employed to characterize the
particles in urban Beijing in the spring of 2011. The whole sampling time was divided into …

Extremely severe haze weather events occurred in many cities in China, especially in the
east part of the country, in January 2013. Comprehensive measurements including hourly …

A long-lasting haze episode has been first observed with a mean atmospheric visibility of 8.6
km since last decades over Xiamen. An Aerodyne Aerosol Mass Spectrometer (AMS) was …

The evolution of physical, chemical and optical properties of urban aerosol particles was
characterized during an extreme haze episode in Beijing, PRC, from 24 through 31 January …

In January 2013, Beijing experienced several serious haze events. To achieve a better
understanding of the characteristics, sources and processes of aerosols during this month …

In this paper we investigate a severe pollution episode that occurred in the Yangtze River
Delta (YRD) region in January 2013. The episode was caused by the combination of …

The composition and size of individual atmospheric particles were measured by aerosol
time-of-flight mass spectrometry (ATOFMS) in Shanghai for the period December 14–23 …
