Non-Methane Hydrocarbon Air Quality Measurements

Tropospheric OH and Cl levels deduced from non-methane hydrocarbon measurements in a marine site

In situ continuous hourly measurements of C 2-C 8 non-methane hydrocarbons (NMHC S) have been performed from March to October 2006 at two coastal locations on the island of Crete, in the Eastern Mediterranean. Well defined diurnal variations were observed for several short lived NMHC S (including ethene, propene, n-butane, 5 n-pentane, n-hexane, 2-methyl-pentane). The daytime concentration of h...

Measurements of hydrocarbon air–surface exchange rates over maize

Vertical gradients of volatile organic compounds (VOCs) were measured over a maize (Zea mays) field, in its early growth period, during May 1995, in the Lower Coastal Plains of North Carolina. These measurements were combined with micrometeorological flux measurements to determine emission flux measurements for various VOCs. This measurement program was part of project NOVA (Natural emissions o...

Measurements and Prediction of Inhaled Air Quality with Personalized Ventilation

This paper examines the performance of five different air terminal devices for personalized ventilation in relation to the quality of air inhaled by a breathing thermal manikin in a climate chamber. The personalized air was supplied either isothermally or non-isothermally (6°C cooler than the room air) at flow rates ranging from less that 5 L/s up to 23 L/s. The air quality assessment was based...
