Volatile Organic Compounds in Alberta, Canada Residences—Evidence from Community Surveys

Differences between measured and reported volatile organic compound emissions from oil sands facilities in Alberta, Canada.

Large-scale oil production from oil sands deposits in Alberta, Canada has raised concerns about environmental impacts, such as the magnitude of air pollution emissions. This paper reports compound emission rates (E) for 69-89 nonbiogenic volatile organic compounds (VOCs) for each of four surface mining facilities, determined with a top-down approach using aircraft measurements in the summer of ...

Volatile organic compounds from leaves litter.

Qualitative composition of volatile emissions of litter of five species of deciduous trees was investigated by GC-MS. The list of identified substances contains more than 70 organic compounds of various classes. It was established that the composition of components emitted by the litter into the gas phase greatly differs from that of essential oils extracted by hydrodistillation from turned lea...

Volatile Organic Compounds in Uremia

BACKGROUND Although "uremic fetor" has long been felt to be diagnostic of renal failure, the compounds exhaled in uremia remain largely unknown so far. The present work investigates whether breath analysis by ion mobility spectrometry can be used for the identification of volatile organic compounds retained in uremia. METHODS Breath analysis was performed in 28 adults with an eGFR ≥ 60 ml/min...

Adsorption of Volatile Organic Compounds from Aqueous Solution by Granular Activated Carbon (GAC) in Batch System

Measurement of Volatile Organic Compounds

To answer critical questions regarding the interactions between green plants and air quality, two three-year projects are underway to investigate emission of volatile organic compounds (VOC) from selected plant species. These biogenic VOC (BVOC) and oxides of nitrogen (NOx) can react in the lower atmosphere in the presence of sunlight to form ozone and secondary particulate matter, the principa...
