PROBLEM STATEMENT: Petroleum hydrocarbons, and other volatile organic compounds (VOCs), which are found to contaminate groundwater and soils, are usually treated by pump-and-treat methods, which are very time-consuming, expensive, and not very effective. We are proposing the use of pervaporation for effectively removing these hydrocarbons and VOCs from contaminated soil and groundwater (with or...

Biotilters are recognized by an increasing number of state air quality regulatory agencies as ”best available control technology” (BACT) for treatment of volatile organic compounds (VOCs) and odor. This has been the case for two cocomposting facilities permitted by Bedminster Bioconversion Corporation in Cobb County, Georgia, and Marlborough. Massachusetts. Both areas are in ozone non-attainmen...

Soil and rhizosphere bacteria produce an array of secondary metabolites including a wide range of volatile organic compounds (VOCs). These compounds play an important role in the long-distance interactions and communication between (micro)organisms. Furthermore, bacterial VOCs are involved in plant pathogens inhibition and induction of soil fungistasis and suppressivenes. In the present study, ...

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 granular activated carbon (GAC) for recovery of volatile organic compounds from water, the equilibrium adsorption was inve...

Plants produce volatile organic compounds (VOCs) in response to herbivore attack, and these VOCs can be used by parasitoids of the herbivore as host location cues. We investigated the behavioural responses of the parasitoid Cotesia vestalis to VOCs from a plant-herbivore complex consisting of cabbage plants (Brassica oleracea) and the parasitoids host caterpillar, Plutella xylostella. A Y-tube ...

A study was conducted to evaluate the. use of volatile organic microbial metabolites, particularly geosmin and 2-methylisoborneol, as indicators of activity of specific groups of microorganisms (actinomycetes, bacteria, or fungi) in soil. Substrates and selective antibiotics were added to soil microcosms to establish different soil microbial communities; volatile organic compounds (VOCs) in the...

Abstract This paper introduces the harm of VOCs, makes a more detailed demonstration and understanding on governance emission characteristics technology key industries in detail, so as to learn from methods volatile organic compounds (VOCs), briefly discusses comprehensive utilization, truly governs VOCs source.

Recently, a number of endophytic fungi have been discovered that produce volatile organic compounds (VOCs) whilst growing on agricultural waste substrates, whose chemistry is best defined as hydrocarbon and hydrocarbon-like. These compounds have potential use as both 'green chemicals' and fuels. This report discusses the discovery of the first fungus proposed as a producer of 'Mycodiesel'. Also...

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...

We analyzed the volatile organic compounds (VOCs) emitted from different soils by using the PTR-MS-TOF technique under laboratory conditions and compared them with soil chemical biochemical activities. The emitted VOCs were related to soil microbial biomass, soil respiration and some soil enzyme activities so as to evaluate if size and activity of soil microbial communities influenced the soil ...
