ambient air VOC Articles

Significance of the Research: Ambient air is polluted by many VOCs coming from Petrochemical Industry. PAMS, Oxygenated or Halogenated VOCs can be found in many ranges of concentration between background and site fence line. These compounds are precursors of ozone and Industrial bodies need to identify them to be in compliance with the authorized limits and to improve their process. ...

Volatile Organic Compounds (VOCs) and odors are natural by-products of many chemical manufacturing processes. The manufacturing of powdered and liquid flavorings & fragrances involves production phases where VOCs and odors can escape into the ambient air. Recapture of the VOCs is important in the prevention of air pollution and smog. Smog is formed when VOCs react with nitrogen oxides (NOx) ...

Due to environmental issues, the world of gas analysis is evolving very rapidly. Governments set the rules to limit and control the environmental pollution through legislation. Volatile organic compounds (VOCs), often produced by human activities, are amongst the sources of pollution that need to be identified and quantified for safety reasons. Exposure to high concentrations of certain VOCs is ...

Ambient air is polluted by many Volatile Organic Compounds (VOCs) coming from anthropogenic and natural sources. VOCs from PAMS, TO14 and TO15 lists can be measured in many ranges of concentration, from ng/m3 up to mg/m3 depending on the location of the measurements. Due to the large number of molecules, the complete separation of all compounds is difficult to perform using chromatographic ...

Ozone concentration has been multiplied by 5 in the last century in the middle latitudes of the northern hemisphere from 10 PPB in 1874 to approximately 50 PPB today. This is an increase of 1.6% per year; the trend is probably higher (2.4% a year) over the last decades. (Chapter 1 of the International Geosphere-Biosphere Program - World Climate Research Program) In order to stop this global ...

Observing this series of photos taken every 30 seconds by OPGAL’s OGI camera (EyeCGas 2.0), shows a significant volatile organic compounds emission (VOCs) event, including methane released into the air. The gas flows through a cold pipe (the black flare structure), and its temperature evens out with the ambient air temperature upon release to the atmosphere. However, since all VOCs emit an ...

More than half of the world’s population lives in cities, and their populations are rapidly increasing. Information on vertical and diurnal characterizations of volatile organic compounds (VOCs) in urban areas with heavy ambient air pollution can help further understand the impact of ambient VOCs on the local urban environment. This study characterized vertical and diurnal variations in ...
