Spectral analysis to identify the distribution of particulate lead (Pb) as exhaust emissions of motorized vehicles has been done using Laser-Induced Breakdown Spectroscopy (LIBS). The soil samples were taken at two different location with various depths 0 cm and 15 cm from population around the highway. Comparison was carried out by mixture of PbCl2 and soil. All samples were pelletized and ablated by QSwitched Nd:YAG laser. The quantitative result shown in spectrum between wavelength and intensity.The spectrum were formed by all samples showed no detectable Pb content. The indentified elements are Magnesium (Mg), Iron (Fe), Tungsten (W), Calcium (Ca), Hydrogen (H), Oxygen (O2), Silicon (Si), Titanium (Ti), Sodium (Na), Manganese (Mn), Alumunium (Al), Thorium (Th), Copper (Cu).
