The heavy metal in atmospheric particulates has great harm to human health, and the rapid detection of heavy metal elements therein is important. The laser-induced breakdown spectroscopy (LIBS) is applied to the rapid elemental analysis of atmospheric particulates, and the results show that atmospheric particulates contain Na, Al, Si, Cu, Mg, Fe and other elements. Taking Ca element as the reference element, we use the internal standard method to quantitatively analyze Pb element in the atmospheric particles. The calibration curve is obtained by fitting, and it is calculated that the limit of detection of Pb element is 34.3×10 -6. Besides, the plasma temperature and electron number density of Pb element are calculated. The experimental results verify the feasibility of LIBS for the qualitative and quantitative analysis of heavy metal elements in atmospheric particulates and provide experimental evidence for monitoring atmospheric heavy metal pollution.
