Qualitative and quantitative analysis of polycyclic aromatic hydrocarbons (PAHs) were performed using a solid-phase micro-extraction (SPME) technique and gas chromatography-flame ionization detector (GC-FID) instrumentation. Several different extraction methods were tested to determine which method gave the most reproducible results. In order to determine how well the GC performed, commercial standards were used to determine the retention time and concentration of 16 PAHs. A 2-point calibration curve using 100 part per billion (ppb) and 20 ppb solutions was constructed for quantitative analysis. Future plans include analyzing river water samples on a regular basis over an extended period of time, and also Soxhlet extraction methods to study PAH levels in river sediments.
