Paper Abstract

We present a unique method for routine monitoring of polycylic aromatic hydrocarbons in water samples. Significant innovations include a rapid solid-liquid extraction procedure, a cryogenic fiber optic probe for fluorescence measurements in frozen matrices at liquid helium temperature (4.2 K) and an instrumental system for laser-excited time-resolved Shpol'skii spectrometry. The potential of this methodology is illustrated with the direct trace analysis of fifteen Environmental Protection Agency priority pollutants in less than 5 minutes.
