Аннотация:The main achievements of the laser-induced breakdown spectroscopy (LIBS) method for the determination of trace and minor components in the environment (soil, ore, natural water, etc.) are discussed. At present unique opportunities LIBS allow its use for the rapid analysis of various samples: metals and alloys, glasses, polymers, geological, archaeological and biological samples, objects of cultural heritage. The high efficiency of its application in remote analysis has been demonstrated. The main advantages of this method (a small amount of material to be analyzed, locality, remote analysis of distinct, widely separated targets from a single vantage point, rapid analysis, and multi-element capability) led to his selection for the rapid analysis of the elemental composition of rocks directly on Mars (Mars rover 'Curiosity'). The review discusses in detail the LIBS opportunities for the express qualitative classification of the environmental samples with the help of discrimination analysis. Different approaches to improve the figures-of-merit of a quantitative analysis of the samples are considered. Detection limits of the most elements in soils, geochemical objects and natural waters obtained until now are critically examined.
