Abstract: The heavy metal elements in aerosol were serious harm to human health. So it was necessary to in-situ and real-time monitor the heavy metals in atmosphere. The research of aerosol by LIBS monitor system continued one month in South Central University for Nationalities. The distribution of PM10 and spectrum intensity of Be element has been obtained in this month. The spectrum of heavy metal by fireworks combustion has been got by using this monitor system. Through qualitative analysis of heavy metal showed the technology could detect heavy metals in aerosol at the same time. Through quantitative analysis of simulated aerosol got Cd、Sr、Na、Pb elements calibration curve. The linear correlation coefficient was more than 0.94. The results will provide a new method for real-time online detection of heavy metals in atmospheric aerosol.

Key words: laser-induced breakdown spectroscopy, aerosol, heavy metal, real-time online
