Detection of heavy metal containment of soil pollution has been made by using laser-induced breakdown spectroscopy (LIBS). A pulsed Nd:YAG laser (1064 nm, 8 ns, 200 mJ) was focused on to a soil sample, which is prepared in the form of pellet, at atmospheric pressure. Emission spectra taken from the oil-contaminated soil and uncontaminated soil were obtained. The contaminated soil has almost the similar spectrum profile and contains the same major and minor elements as for the uncontaminated soil case. However, C-H molecular band was clearly detected in oil-contaminated soil, while no C-H band was detected in uncontaminated soil. For comparison, the emission spectra of contaminated and uncontaminated soil were also obtained by using XRD method, showing that the spectra taken by using LIBS is much better than the XRD case indicated by signal to noise ratio (S/N ratio).
