MTBE and other volatile organic compounds—New ﬁ ndings and implications on the quality of source waters used for drinking-water supplies 1 Detection does not necessarily translate to risk. The NAWQA Program measures chemicals at very low concentrations, often 10 to times lower than EPA standards and health Size: 47KB. Volatile Organic Compounds Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. This is a very broad set of chemicals. VOCs include a variety of chemicals, some of which may have short and long-term adverse health effects. Concentrations of many VOCs are consistently higher.

Microbial volatile organic compound database. Here we present the mVOC Database which is based on extensive literature search for microbial volatile organic compounds (mVOCs) and is an extension and improvement of the first mVOC database launched in (Lemfack et al. ). Bacteria and fungi, similar to plants and animals, emit small compounds and are an . In this paper, we have modeled and analyzed affinities and kinetics of volatile organic compounds (VOCs) adsorption (and desorption) on various surface chemical groups using multiple self Cited by:

This technical report presents a summary of indoor air studies that measured background concentrations of Volatile Organic Compounds (VOCs) in the indoor air of thousands of North American residences and an evaluation and compilation of the.
This study investigated the concentrations of the most abundant volatile organic compounds (VOCs) in eight naturally ventilated school buildings in Italy.
The schools were chosen to include areas with different urbanization and traffic density characteristics in order to gather a more diverse picture of exposure risks in the different areas of Cited by: Volatile Organic Compound Concentrations and Emission Rates in New Manufactured and Site-Built Houses A.T.
Hodgson1, A.F. Rudd2, D. Beal2, S. Chandra2 Abstract Concentrations of 54 volatile organic compounds (VOCs) and ventilation rates were measured in four new manufactured houses over 2 - months following installation and in seven new site.

The NO 2 concentrations were higher in the urban area, followed by industrial area and rural areas. For benzene, its concentration in the industrial area was significantly higher than in the urban and Cited by: George D. Thurston, in International Encyclopedia of Public Health (Second Edition), Volatile Organic Compounds.
Volatile organic compounds (VOCs) are organic chemicals that readily produce vapors at ambient temperatures, and are therefore emitted as gases from certain solids or liquids. All organic compounds contain carbon, and organic chemicals are the basic.
Ambient concentrations of volatile organic compounds (VOC) and nitrogen dioxide (NO2) were measured by means of passive sampling at 40 sampling points.

The results indicated that toluene and α-pinene are the most dominant emission rates of individual components decreased Cited by: This study differs from prior research in its use of a community-based process to identify sampling locations.
Through this approach, we determine concentrations of volatile compounds in air near operations that reflect community concerns and point to the need for more fine-grained and frequent monitoring at points along the production life by: Valle Galeria, a location in the outskirts of Rome, was selected as a case study to assess the pollution release from the industrial facilities operating in this area.
For this purpose, an intensive field campaign was conducted during summer, where volatile organic compounds VOC (including benzene, toluene and xylenes) were sampled and analyzed at two different by: Background: High levels of household air pollution (HAP) occur in houses of many developing countries due to combustion of biomass fuels (wood, charcoal, cow dung, crop residues) in the households in open fires or inefficient stoves.
Particulate Matter (PM) and Volatile Organic Compounds (VOCs) are among the significant pollutants that are generated Author: David Mulenga, Hebert Tato Nyirenda, Prispa Mwila, Chibangula M. Chileshe, Seter Siziya. A multitude of sources of volatile organic compounds (VOCs) are common to the retail environment.
Volatile organic compounds can be odorous, irritating or carcinogenic. Through a field investigation and modeling study, this dissertation investigates exposure to, and control of, VOCs in retail buildings. Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air, a trait known as example.
Sampling strategies for volatile organic compounds (VOCs) in indoor air. Report No 14, EUR EN Luxembourg: Office for Official Publications of the European Community.
Strategies for sampling chemical substances in indoor air have been discussed in a previous report of this series (Report No 6).File Size: 2MB. Volatile organic compounds in indoor air: a review of concentrations measured in North America since Article (PDF Available) May with 1, Reads How we measure 'reads'.
In a new study, researchers present the world's first chemical fingerprint of urban emission sources of volatile organic compounds (VOCs). Accordingly, the abatement strategy for organic solvents.
Most organic compounds are non-polar = hydrophobic -settle in bottom feeders and particulate matter (soils) = food chain transfer Poly aromatic compounds are hydrophilic settle in the waters and are recycled easily.-The degree of chlorination affects their persistence in the environment.
Highly chlorinated compounds are more refractory. Sources and Concentrations of Formaldehyde and Other Volatile Organic Compounds in the Indoor Air of Four Newly Built Unoccupied Test Houses Abstract Concentrations of formaldehyde and other volatile organic compounds (VOCs) were monitored over a 2-year period in the main rooms of four unoc cupied test houses and in the outdoor air.
Concentrations of 54 volatile organic compounds (VOCs) and ventilation rates were measured in four new manufactured houses over 2-to months following installation and in seven new site-built houses 1-to-2 months after completion.
The houses were in four projects located in hot-humid and mixed-humid climates. They were finished and operational, but. Volatile organic compounds (VOCs) are defined as carbon-based organic compounds that put negative impacts on nervous system through respiration.
The objective of this study was to assess concentrations of VOCs at a new school building and to compare the concentration by different variables.
