Abstract

Chlorinated hydrocarbons (CHCs) are among the most frequently detected volatile organic compounds in North American ground-water supplies. They have been widely used in the chemical industry as solvents and degreasing agents. The average concentration level for CHCs in our aquatic environment ranges from high-ppb for chloroform to low-ppb level for tetrachloroethylene(PCE). Methods used for detecting these compounds in the environment require high sensitivity and high selectivity. Conventional detection methods for CHCs include gas chromatography(GC) or GC/MS. Although these techniques do possess the required sensitivity and selectivity, they lack the capability of performing in-situ measurements.
