Screening environmental pollutants and biomarkers: The analytical challenge
Detailed characterization of most chemical pollutants in environmental samples from industrial and waste sites is possible using analytical techniques such as liquid or gas chromatography and mass spectroscopy. But for many environmental monitoring programs and assessment applications, these analytical procedures would be needlessly time-consuming and expensive. It is often desirable to have a screening procedure to prioritize environmental samples before detailed analyses are conducted on a subset of samples to reduce the total cost of monitoring programs and environmental studies. This presentation describes various screening techniques, such as synchronous fluorescence (SF), and room temperature phosphorescence (RTP), and provides an overview of advanced analytical techniques and instrumentation, such as surface-enhanced Raman scattering (SERS) and antibody-based fiberoptics sensors, used to detect trace levels of chemical pollutants and related biomarkers in complex environmental samples. 28 refs., 6 figs.
