The authors describe the application of fluorimetry to determine low levels of cable oil contamination in various soil types. The study has utilised a simple extraction technique using two different solvents to investigate their efficiency, speed and reproducibility. The sensitivity of the fluorimeter has also bess assessed and the results discussed and compared with those obtained by FTIR spectroscopy. The results indicate that extraction efficiency over 80% is obtainable when hexane is used to extract the oil from the soil. The technique has a sensitivity of approximately 10ppm (w/w) and has an accepable accuracy of measurement of over 80%.
