Laser-induced breakdown spectroscopy (LIBS) has the benefits of simultaneous multi-element detection capability, online/in-situ measurement capability without physical intervention and being regarded as a versatile analytical technique for gases, liquids, solids and aerosols. Thus, LIBS has the potential of application in the multiple environmental monitoring fields like air, water and soil monitoring. As to different samples, the developments of sample preparing, experimental setup, data processing and the figure of merit, were reviewed based on researches of these years. The application status and future developments were also summarized.
