Insights Into Microplastics Pollution in Aquatic Ecosystem: a Short Review of Sampling and Analysis Methods
AI summary Read the abstract
This review summarizes current methods for sampling and analyzing microplastics in rivers and estuaries, including techniques like FTIR and Raman spectroscopy for polymer identification. The authors highlight the need for standardized sampling and analysis methods to ensure that microplastic data across different studies are reliable and comparable.
The prevalence of microplastics in the environment and their potential adverse impacts on wildlife and human well-being make them a pressing global ecological issue. The objective of this review is to provide better understanding prevalence and distribution of microplastics, factors influencing their concentration and transport, the sampling technique and polymer identification analysis used in various studies and future research needs. The identification of microplastic polymer types is also explored, including techniques such as Fourier-transform infrared spectroscopy (FTIR) and Raman spectroscopy. It also points out the many types of sampling equipment and materials, as well as sample preparation and analysis. Sampling method and polymer identification analysis of microplastics may vary on the circumstances of the location and question of the research. Suitable and standardize for both methods should be prioritized to ensure reliable and precise collection of data regarding the microplastic in river and estuarine.
