“…Additionally, components of additives, such as Al, Ca, Mg, Na, and Si, or antioxidants in microplastics are captured as markers and used for identification using EDS [25,32]. Determining the surface elemental composition of a particle can be useful for identifying carbon-rich plastics from inorganic particles [39,46]. However, SEM and TEM limit the number of samples that can be processed because the equipment is expensive, and sample preparation and inspection require significant time and effort.…”

Microplastics are found in various environments with the increasing use of plastics worldwide. Several methods have been developed for the sampling, extraction, purification, identification, and quantification of microplastics in complex environmental matrices. This study intends to summarize recent research trends on the subject. Large microplastic particles can be sorted manually and identified through chemical analysis; however, sample preparation for small microplastic analysis is usually more difficult. Microplastics are identified by evaluating the physical and chemical properties of plastic particles separated through extraction and washing steps from a mixture of inorganic and organic particles. This identification has a high risk of producing false-positive and false-negative results in the analysis of small microplastics. Currently, a combination of physical (e.g., microscopy), chemical (e.g., spectroscopy), and thermal analyses is widely used. We aim to summarize the best strategies for microplastic analysis by comparing the strengths and limitations of each identification method.

Background Due to the increasing usage of plastic, microplastics or plastic particles with a length of 1 to 5 mm are omnipresent in the environment, including freshwater, agricultural soil and seas. The majority of plastic trash is made up of microplastic debris, which has lately started to threaten ecosystems. This calls for immediate management and analysis to ensure the traceability of microplastics in the environment. The main body of the abstract The polymeric variety, irregular shape and microscopic size of microplastics make it difficult to quantify their presence in the environment. In this review, the analytical techniques for evaluating microplastics are discussed. The techniques included Fourier transform infrared spectroscopy, Raman spectroscopy, laser diffraction particle, thermal analysis, scanning electron microscope, pyrolysis gas chromatography, dynamic light scattering, and atmospheric solid analysis probe (ASAP) paired with quadrupole mass spectrometry (MS). Short conclusion The purpose of the present review is to give a summary of the most efficient cutting-edge techniques for more accurate and precise microplastic examination in the environmental samples.
