Advance of Airborne Microplastic Particle Identification Methods
With the increasing global plastic pollution crisis,identification methods of airborne microplastic particles have been regarded as a crucial issue.This paper reviewed the progress made in this area in recent years.Commonly used air sample collection methods were described,including passive sampling and active sampling.Sample preparation methods,such as sieving,digestion,and density separation were discussed.Besides,microplastic particle identification methods,such as microscopic observation,Fourier transform infrared spectroscopy,and Raman spectroscopy were highlighted.However,there are still some challenges in the existing identification methods,such as the number and size distribution of microplastic particles.Future researches focused on the development of sensitive detection and databases establishment to enable large-scale monitoring were suggested.It was also recommended to establish complete and standardized airborne microplastic sampling and analysis technology.The present review concludes the current status of identification methods for airborne microplastic particles and point outs an outlook on future development directions,which provides a theoretical basis for the control of atmospheric microplastic pollution.
