Water quality monitoring is a critical part of environmental management and protection, and to be able to qualitatively and quantitatively determine contamination and impurity levels in water is especially important. Compared to the currently available water quality monitoring methods and techniques, laser-induced breakdown spectroscopy (LIBS) has several advantages, including no need for sample pre-preparation, fast and easy operation, and chemical free during the process. Therefore, it is of great importance to understand the fundamentals of aqueous LIBS analysis and effectively apply this technique to environmental monitoring. This article reviews the research conducted on LIBS analysis for liquid samples, and the article content includes LIBS theory, history and applications, quantitative analysis of metallic species in liquids, LIBS signal enhancement methods and data processing, characteristics of plasma generated by laser in water, and the factors affecting accuracy of analysis results. Although there have been many research works focusing on aqueous LIBS analysis, detection limit and stability of this technique still need to be improved to satisfy the requirements of environmental monitoring standard. In addition, determination of nonmetallic species in liquid by LIBS is equally important and needs immediate attention from the community. This comprehensive review will assist the readers to better understand the aqueous LIBS technique and help to identify current research needs for environmental monitoring of water quality.

“…To achieve spectra with good signal-to-noise and signal-to-continuum ratio some gate delay relative to the laser pulse (55-210 ns [12]) and gate width (200 ns [12]) are used. Therefore, if the gate delay exceeds the recombination time of ions then the population of the upper level N 2 will be determined mostly by collision of the electron with atom (ion) in the ground state.…”

“…Herewith the elemental analysis and spectral characteristics of laser breakdown on a liquid surface are scarcely investigated. It should be noted work [10] in which the distribution of Ca 2+ ion in water and biological samples is investigated, as well as works [11][12][13] in which temporal behavior of emission of plasma generated on the sea water surface is described and detection limits of elements is determined [13].…”

It's shown that the increasing of electron impact excitation rate constant lead to increasing of line intensity, so the limit of detection (LOD) is lower. For femtosecond laser plasma generated on the sea water surface, the relation of the detection limits will be LOD(Na) < LOD(Ca) < LOD(Mg). The fact that the atomic line of Ca I 422 nm is more sensitive for femtosecond laser-induced breakdown spectroscopy is described.

Robust Remote Sensing of Trace‐Level Heavy‐Metal Contaminants in Water Using Laser Filaments

Water is the major natural resource that enables life on our planet. Rapid detection of water pollution that occurs due to both human activity and natural cataclysms is imperative for environmental protection. Analytical chemistry–based techniques are generally not suitable for rapid monitoring because they involve collection of water samples and analysis in a laboratory. Laser‐based approaches such as laser‐induced breakdown spectroscopy (LIBS) may offer a powerful alternative, yet conventional LIBS relies on the use of tightly focused laser beams, requiring a stable air–water interface in a controlled environment. Reported here is a proof‐of‐principle, quantitative, simultaneous measurement of several representative heavy‐metal contaminants in water, at ppm‐level concentrations, using ultraintense femtosecond laser pulses propagating in air in the filamentation regime. This approach is straightforwardly extendable to kilometer‐scale standoff distances, under adverse atmospheric conditions and is insensitive to the movements of the water surface due to the topography and water waves.
