Indoor Volatile Organic Compounds and Chemical Sensitivity Reactions

Indoor Volatile Organic Compounds and Chemical Sensitivity Reactions

Studies of unexplained symptoms observed in chemically sensitive subjects have increased the awareness of the relationship between neurological and immunological diseases due to exposure to volatile organic compounds (VOCs). However, there is no direct evidence that links exposure to low doses of VOCs and neurological and immunological dysfunction. We review animal model data to clarify the rol...

Removal of Indoor Volatile Organic Compounds

Volatile organic compounds (VOCs) and formaldehyde are ubiquitous in indoor environment. 16 Inhalation of VOCs can cause irritations, difficulty breathing, and nausea, and damage the central 17 nervous system as well as other organs. Formaldehyde is even a carcinogen. Removal of VOCs and 18 formaldehyde is thus critical to control indoor air quality (IAQ). Photocatalytic oxidation has been 19 d...

Mathematical Modeling for Volatile Organic Compounds Removal in a Biofilter: Model Validation and Sensitivity Analysis

Chemical characterization of volatile organic compounds on animal farms

More than one hundred volatile organic substances were identified by gas chromatography and mass spectrometry (GC/MS) in the indoor and outdoor air, stable and farm road dust and farm soil samples from two pig and cattle farms in the South Moravian Region. Volatile fatty acids (acetic, propanoic, butanoic and pentanoic acids) and their esters dominated along with aldehydes (butanal, pentanal an...

Catalytic Oxidation of Volatile Organic Compounds and Malodorous Organic Compounds

This thesis describes efforts made on the development of an existing catalytic incinerator. The development work, called process characterization, consists of four general parts. These are the development of measurement methodology, the studying of construction materials, the selection of suitable catalysts and the testing of the effects of process operation conditions. The two application area...
