Abstract A gas chromatographic (GC) method for the determination of petroleum hydrocarbons (PH) in the boiling range from 175°C to 525°C (C10−C40 alkane) in soil was evaluated. The extraction was carried out using minimal amounts of acetone and heptane, prior to a clean up with silica gel. The extraction procedure was tested by means of standard solutions of petroleum products and soil samples. The clean up procedure did not have any significant effect on the amounts of petroleum hydrocarbons present and hydrocarbons of natural origin were removed effectively. The recovery of the extraction and clean up procedure for petroleum products in soil was greater than 90%. The standard deviation for the repeatability was estimated to be less than 10% based on multiple analyses of homogenized soil samples. The detection limit for soil was determined to be 10 mg/kg dry matter. Comparing the GC method with the widely used infrared spectrometry (IR) method in combination with a Soxhlet-extraction using Freon-113, the results obtained are equivalent.
