Volatile organic compounds are important flavor components of finished wines. In addition to winemaking practices, which shape wine quality, cultivation of the grape berries in the vineyard each season affects the production of volatile organic compounds as well as other chemical components that ultimately contribute to our perception of flavor in finished wines. By studying how berry flavor co...

A hybrid nanostructure based on reduced graphene oxide and ZnO has been obtained for the detection of volatile organic compounds. The sensing properties of the hybrid structure have been studied for different concentrations of ethanol and acetone. The response of the hybrid material is significantly higher compared to pristine ZnO nanostructures. The obtained results have shown that the nanohyb...

BACKGROUND Proton transfer reaction-mass spectrometry (PTR-MS), in its recently developed implementation based on time-of-flight mass spectrometry (PTR-TOFMS), was used to rapidly determine the volatile compounds present in fruits of Capsicum spp. RESULTS We analyzed the volatile organic compounds emission profile of freshly cut chili peppers belonging to three species and 33 different cultiv...

Introduction Petroleum spills and leaking underground storage tanks comprise a significant portion of remediation projects. Soil removal and disposal is determined based on the contaminants and concentrations present. Specific target analytes are associated with this type of contamination. A number of these compounds are classified as volatile organics and are used to assess the severity of the...

in this work some quantitative structure activity relationship models were developed for prediction of three bioenvironmental parameters of 28 volatile organic compounds, which are used in assessing the behavior of pollutants in soil. these parameters are; half-life, non dimensional effective degradation rate constant and effective péclet number in two type of soil. the most effective descripto...

In this research, we investigated the sorptive behavior of a mixture of 14 volatile and semi-volatile organic compounds (four aromatic hydrocarbons (benzene, toluene, p-xylene, and styrene), six C2-C5 volatile fatty acids (VFAs), two phenols, and two indoles) against three metal-organic frameworks (MOFs), i.e., MOF-5, Eu-MOF, and MOF-199 at 5 to 10 mPa VOC partial pressures (25 °C). The selecte...

The onset of non-communicable disease has been attributed in large part to environmental exposure to toxic chemicals, including persistent organic pollutants, volatile and semi-volatile organic compounds and transition metals. This review summarizes recent research into the causes and mechanisms of environmental disease onset and examines the role of oxidative stress as well as steps that can b...

The protection of paintings and other objects in collections is a major concern for museum administrators, conservators and national authorities. Artwork may get damaged by accumulation of air pollutants inside protective enclosures due to emissions of volatile and semi-volatile compounds from the exposed objects or from the enclosure itself. Relatively little is known about emissions and depos...
