The troposphere, the region of the Earth’s atmosphere in which we live and breath, is composed of many different kinds of gases. These components range from the abundant two-atom molecules O2 and N2, to larger and more reactive chemicals, which include vast numbers of different volatile organic compounds (VOCs). Concentrations of VOCs can be as high as one part per million by volume (10 , or pp...

Smog pollution is one of China’s most pressing public health issues today and has therefore received significant attention worldwide. Not only cities but also villages in China are suffering from smog pollution, especially since 2013. However, there is limited information available about public awareness on smog pollution in China, especially for where it concerns the residents living in villag...

Abstract. Nitro-aromatic compounds (NACs) were measured hourly at a rural site in China during wintertime to monitor the changes due local and regional impacts of biomass burning (BB). Concurrent continuous measurements concentrations 16 NACs gas particle phases performed with time-of-flight chemical ionization mass spectrometer (CIMS) equipped Filter Inlet for Gases AEROsols (FIGAERO) unit usi...

The effects of 26 individual volatile organic compounds (VOCs) on ozone formation, NO oxidation, and OH radical levels were measured by adding them to reactive organic gas (ROG) NOx air environmental chamber irradiations representing a simplified model photochemical smog system. These experiments had relatively low ROG/NOx ratios to represent conditions where ozone formation is most sensitive t...
