Abstract:

Microplastics are plastic fragments or particles less than 5 mm in size, which can exist in the atmosphere, soil and water for a long time. In recent years, the vigorous development of plastic industry produced serious environmental pollution. Microplastics can enrich in aquatic products through the food chain and harm human health. This review summarized the widely used methods for digesting aquatic product tissues and their removal effects on biological tissues, introduced the conventional methods for separating and staining the solution density of digested aquatic product tissues and briefly introduced the advantages and disadvantages of using electron microscopy, Fourier infrared spectrometer, Raman spectrometer, the Py-GC/MS for idenjpgying microplastic. Finally, the rapid analysis methods proposed in recent two years were collected. Spectroscopy as a classical detection method, often used to idenjpgy microplastic larger than 50 μm in size, as a supplementary method to the thermal cracking of temperament method can accurately idenjpgy 50 μm to nanoscale plastic particles, within the scope of implementation in μg reliable quantitative. However, the sample preparation and analysis time of instrumental analysis methods is relatively long, and their applicable scopes are different. Therefore, future study and development should be more in the direction of high throughput, more flexible and easier to operate.
