BLUNDEN, JESSICA. Characterization of Non-Methane Volatile Organic Compounds at Swine Facilities in Eastern North Carolina. (Under the direction of Dr. Viney P. Aneja) A total of 110 samples of volatile organic compounds (VOCs) were collected and analyzed in a field study to characterize such compounds emitted at six swine facilities in Eastern North Carolina between April 2002 and March 2003 a...

We used a one-dimensional model to simulate the chemical evolution of air masses in the tropical Atlantic Ocean, with a focus on halogen chemistry. The model results were compared to the observations of inorganic halogen species made in this region. The model could largely reproduce the measurements of most chlorine species, especially under unpolluted conditions, but overestimated sea salt chl...

OBJECTIVE morning breath contains elevated concentrations of volatile sulphur components (VSCs). Therefore, morning breath is recognised as a surrogate target for interventions on breath quality. Nevertheless, factors influencing morning breath are poorly understood. Our aim was to evaluate concentrations of VSC at the time of awakening. METHODS a procedure was developed to collect breath sam...

There is an urgent need to develop odor reduction technologies for animal production facilities, and this requires a reliable measurement technique for estimating the removal of odorants. The purpose of the present experiment was to investigate the application of proton-transfer-reaction mass spectrometry (PTR-MS) for continuous measurements at a biofilter from SKOV A/S installed at a pig produ...
