Abstract :
Summary form only given. A laser spectroscopic measurement method is presented to trace in situ chemical pollution in the marine environment. Raman spectroscopy is used because it is a nonintrusive method yielding finger printing spectra of the analytes suitable for substance identification and for quantitative analysis.
