The ability of soil venting to inexpensively remove large amounts of volatile organic compounds (VOCs) from contaminated soils is well established. However, the time required using venting to remediate soils to low contaminant levels often required by state and federal regulators has not been adequately investigated. Most field studies verify the ability of a venting system to circulate air in ...

epoxyalcohols are useful intermediates in complex organic synthesis, and recently they have been recognized as versatile intermediates for synthesis of natural products. the treatments of cis and trans 2-(1-cyclohexenyl) cyclohexanol, separately with paranirto perbenzoic acid gave the corresponding 2-(1- cyclohexenyl) cyclohexanol oxide. on the other hand, 2-cyclohexylidene cyclohexanol oxide w...

industrial waste management is one of the most properly approaches which make industry and environment collaborating and coacting as well as reduce impacts of industry on environment. in this study, present management of yazd industrial township located in yazd province was studied. in order to properly manage and control waste production, questionnaires were used to collect data regarding type...

In this work, we have evaluated how well the general assisted model building with energy refinement (AMBER) force field performs in studying the dynamic properties of liquids. Diffusion coefficients (D) have been predicted for 17 solvents, five organic compounds in aqueous solutions, four proteins in aqueous solutions, and nine organic compounds in nonaqueous solutions. An efficient sampling st...

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...

This paper evaluates the feasibility of using shredded tires for removal of organic compounds from landfill leachate. From the batch sorption isotherm experiments, tire chips were found to have 1.4% to 5.6% of the sorption capacity of granular activated carbon on a volume basis. The sorption equilibrium occurred within 2 days for 0.6-, 1.3-, and 2.5-cm size tire chips. The capacity of tire chip...

Personal exposures of 100 adult non-smokers living in the UK, as well as home and workplace microenvironment concentrations of 15 volatile organic compounds were investigated. The strength of the association between personal exposure and indoor home and workplace concentrations as well as with central site ambient air concentrations in medium to low pollution areas was assessed. Home microenvir...
