Description:
The U.S. Environmental Protection Agency is interested in field screening hazardous waste sites for contaminants in the soil and surface and ground water. his study is an initial technical overview of the principal molecular spectroscopic techniques and instrumentation currently available for field screening. The goal has been to describe the power and utility of molecular (optical) spectroscopic techniques for hazardous waste site screening and to define the main strengths, weaknesses, and applications of each major spectroscopic technique. A brief discussion is also given for some other techniques that rely on spectroscopic detection: colorimetry and fluorometry, as well as immunoassay and fiber-optic chemical sensors. he cost of instrumentation and analysis and the time requirements are briefly discussed. road guidelines are provided for the three categories of instrumentation: portable, field-deployable and semi-field-deployable. n outline of the spectroscopic principles and instrumentation for each particular spectroscopic techniques is given along with a description of state-of-the-art approaches. dvantages, limitations, sensitivities and examples of specific techniques and their applications to environmental contaminants are also discussed.
