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 char
Detection of Para-Cymene, a Microbial-Generated Volatile Organic Compound (MVOC), By Use of a Bioluminescent Biosensor, a Proof of Concept
All environments inhabited by humans contain microbes. The detection and elimination of harmful fungi and bacteria in closed system environments such as spacecraft is of vital importance. Biological waste products of microbes can cause “sick building syndrome,” structural damage,
Distributions of Volatile Organic Compounds (vocs) in Indoor and Outdoor Air among Industrial, Urban and Suburban Neighborhoods
This paper presents results of a comprehensive survey conducted to better understand concentrations and spatial variations of indoor and outdoor concentrations of volatile organic compounds (VOCs) in industrial, urban and suburban neighborhoods. Three cities, representing these t
Volatile organic compounds in the breath of patients with schizophrenia.
AIMS To analyse the breath of patients with schizophrenia for the presence of abnormal volatile organic compounds. METHODS A case comparison study was performed in two community hospitals in Staten Island, New York. Twenty five patients with schizophrenia, 26 patients with other
Comparison of the neurotoxicities between volatile organic compounds and fragrant organic compounds on human neuroblastoma SK-N-SH cells and primary cultured rat neurons
These are many volatile organic compounds (VOCs) that are synthesized, produced from petroleum or derived from natural compounds, mostly plants. Fragrant and volatile organic compounds from plants have been used as food additives, medicines and aromatherapy. Several clinical and
Measurements of chlorinated volatile organic compounds emitted from office printers and photocopiers
Office devices can release volatile organic compounds (VOCs) partly generated by toners and inks, as well as particles of paper. The aim of the presented study is to identify indoor emissions of volatile halogenated organic compounds into the office workspace environment. Mixture
Adsorption of Volatile Organic Compounds from Aqueous Solution by Granular Activated Carbon (GAC) in Batch System
Chlorinated hydrocarbons and aromatics are the major volatile organic compounds that contaminate the ground water and industrial waste waters. The best way to overcome this problem is to recover the dissolved compounds in water. In order to evaluate the potential ability of granu
Exposure to Volatile Organic Compounds and Possibility of Exposure to By-product Volatile Organic Compounds in Photolithography Processes in Semiconductor Manufacturing Factories
OBJECTIVES The purpose of this study was to measure the concentration of volatile organic compound (VOC)s originated from the chemicals used and/or derived from the original parental chemicals in the photolithography processes of semiconductor manufacturing factories. METHODS A t
Finnish Meteorological Instittute Contributions No. 56 Sources and Concentrations of Volatile Organic Compounds in Urban Air
Volatile organic compounds (VOCs) have a great influence on tropospheric chemistry; they affect ozone formation and they or their reaction products are able to take part in secondary organic aerosol formation; some of the VOCs are themselves toxic. Knowing the concentrations and
Emission, oxidation, and secondary organic aerosol formation of volatile organic compounds as observed at Chebogue Point, Nova Scotia
[1] We report the detection of a class of related oxygenated compounds by proton-transfer-reaction mass-spectrometry (PTR-MS) that have rarely or never been observed as a group using in situ instrumentation. Measurements were made as part of the International Consortium for Atmos
