“…The limited area of THF contamination indicates that it is likely not associated with chlorinated-solvent use and disposal at this site. While 90% of the dioxane production was for use as a solvent stabilizer, THF is largely used as a solvent in synthetic processes (3) and in particular it is used as a solvent in the glue used with PVC pipes (35). However, the absence of THF in groundwater samples from 23 of 27 wells suggests that the PVC casings in the monitoring wells are not leaching THF to the groundwater.…”

“…The in-house deionized water was determined to contain approximately 2 µg/L THF. Wang et al observed up to 13 000 µg/L THF in laboratory deionized water and they concluded that the glue used with PVC pipes was the source of the THF (35). The source of the THF contamination was determined to be the deionized water; the contamination was eliminated by discontinuing conditioning the disk with deionized water.…”

Groundwater contamination by cyclic ethers, 1,4-dioxane (dioxane), a probable human carcinogen, and tetrahydrofuran (THF), a co-contaminant at many chlorinated solvent release sites, are a growing concern. Cyclic ethers are readily transported in groundwater, yet little is known about their fate in environmental systems. High water solubility coupled with low Henry's law constants and octanol-water partition coefficients make their removal from groundwater problematic for both remedial and analytical purposes. A solid-phase extraction (SPE) method based on activated carbon disks was developed for the quantitative determination of dioxane and THF. The method requires 80 mL samples and a total of 1.2 mL of solvent (acetone). The number of steps is minimized due to the "in-vial" elution of the disks. Average recoveries for dioxane and THF were 98% and 95%, respectively, with precision, as indicated by the relative standard deviation of <2% to 6%. The method quantitation limits are 0.31 microg/L for dioxane and 3.1 microg/L for THF. The method was demonstrated by analyzing groundwater samples for dioxane and THF collected during a single sampling campaign at a TCA-impacted site. Dioxane concentrations and areal extent of dioxane in groundwater were greater than those of either TCA or THF.

Several billion pounds of ketones are produced annually for industrial use in the United States and worldwide. Those with the highest production volumes include acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, 4‐hydroxy‐4‐methyl‐2‐pentanone, isophorone, mesityl oxide, and acetophenone. Common methods used to manufacture ketones include aliphatic hydrocarbon oxidation, alcohol dehydration with subsequent oxidation, dehydrogenation of phenol, alkyl aromatic hydrocarbon oxidation, and condensation reactions. Ketones are commonly used in industry as solvents, extractants, chemical intermediates, and, to a lesser extent, flavor and fragrance ingredients. Although a common effect of excessive ketone exposure is CNS depression some ketones have pulmonary effects that are well below levels that cause acute CNS effects. For example, ketones such as diacetyl and chemically similar chemicals used for flavoring foods, coffee, and e‐cigarettes provide opportunities for widespread exposure and very debilitating pulmonary disease including bronchiolitis obliterans.

A ketone is an organic compound containing a carbonyl group (CO) attached to two carbon atoms and can be represented by the general formula Several billion pounds of ketones are produced annually for industrial use in the United States. Those with the highest production volumes include acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, 4‐hydroxy‐4‐methyl‐2‐pentanone, isophorone, mesityl oxide, and acetophenone. Common methods used to manufacture ketones include aliphatic hydrocarbon oxidation, alcohol dehydration with subsequent oxidation, dehydrogenation of phenol, alkyl aromatic hydrocarbon oxidation, and condensation reactions. Ketones are used because of their ease of production, low manufacturing cost, excellent solvent properties, and desirable physical properties such as low viscosity, moderate vapor pressure, low to moderate boiling points, high evaporation rates, and a wide range of miscibility with other liquids. The low‐molecular‐weight aliphatic ketones are miscible with water and organic solvents, whereas the high‐molecular‐weight aliphatic and aromatic ketones are generally immiscible with water. Most ketones are chemically stable. The exceptions are mesityl oxide, which can form peroxides, and methyl isopropenyl ketone, which polymerizes. Most ketones are generally of low flammability. Ketones are commonly used in industry as solvents, extractants, chemical intermediates, and to a lesser extent, flavor and fragrance ingredients. Ketones have also been reported in the ambient air, in wastewater treatment plants, and in oil field brine discharges.
