The majority of environmentally relevant substances can be quantitatively analyzed in various matrices — provided that the samples may be sent to an analytical laboratory. The analysis there involves an extraction and a clean-up step prior to the -mostly chromatographic — separation and analysis. Thus this procedure is quite time-consuming. Moreover, these laboratory based techniques are very costly if continuous monitoring is necessary or if hundreds of soil samples have to be analysed to assess the hazard potential of a particular site. For these screening and monitoring applications optical methods are much more suitable.
