This paper provides an overview of the principles and applications of two spectroscopic methods, synchronous luminescence (SL) and room temperature phosphorescence (RTP), used as rapid screening tools for monitoring polynuclear aromatic compounds in real-life samples. Two practical examples, a screening procedure of various coal products and a characterization procedure of the total particulate matter from cigarette smoke condensates, will illustrate the efficacy of the SL and RTP techniques. The paper will also briefly review other applications of the SL and RTP techniques in the areas of environmental and industrial process control.
