“…Onshore sampling is best to be performed in the swash zone (Figure 3), where MPs tend to accumulate under waves action [79] or underwater, at different depths. Underwater sampling, for both fluvial and lacustrine environments, can be done at different depths, acknowledging the fact that a finer texture of the sediment usually accumulates a higher quantity of MPs that can be occasionally visually observed.…”

“…Nevertheless, preservation techniques are also employed to retard biological changes that inevitably continue after the sample is removed from the parent matrix [79,87]. In some cases, the identification and characterisation of the biological matter can be relevant to other aspects of the research [88,89] and the use of various fixing solutions (70-80% ethanol, 4-5% formalin) to preserve the biological material is generally reported [72,86,89,90].…”

A Practical Overview of Methodologies for Sampling and Analysis of Microplastics in Riverine Environments

et al. 2020

Microplastics have recently been stated as being remarkable contaminants of all environmental matrices. The lack of consistent and standardised methods and protocols used to evaluate and quantify microplastics present in riverine systems made a comparison among different studies a critical issue. Based on literature research and the practical expertise of the authors, this work presents a complete collection and analysis of procedures concerning the monitoring of microplastics in riverine environments, focusing on their sampling and analytical protocols to identify, quantify, and characterise them. Further details regarding the advantages and disadvantages of each analytical technique described, such as general recommendations and suggestions, are provided to give practical support for analytical procedures. In particular, microplastics studies consist firstly of their sampling from the aquatic compartment (aqueous and solid phase). Based on the goal of the research, specific devices can be used to collect particles from different matrices. It follows their quantification after extraction from the environmental matrix, adopting different protocols to isolate microplastics from a large amount of organic matter present in a riverine system. In the end, additional qualitative analyses (e.g., RAMAN and FTIR spectroscopy, GC-MS) are required to identify the chemical composition of particles for a better image regarding the abundance of polymer types, their origin, or other information related to manufacturing processes.

“…In Jiaojiang and Oujiang estuaries, the abundances were found to be 955 and 680 items/m 3 , respectively (Zhao et al 2015a(Zhao et al , 2015b. In Pearl River, where it runs through Guangzhou City, the abundance in surface water was 379-7924 items/m 3 and 80-9598 items/kg dry weight sediments (Lin et al 2018). Still, PE and PP are the most commonly found types of microplastics.…”

Research on microplastics in China is progressing rapidly. Within recent years, more than 30 research institutes have conducted research on marine microplastic in estuaries, coasts, open sea, and Polar regions. Microplastics have been detected in freshwater systems (lakes, rivers, and wastewater treatment plants) and coastal and marine environments. This paper reviews the research progress of microplastics in China, providing information on topics including the methodology, quantification of microplastics in various habitats, eco-toxicological effect, biodegradation, management, and control of plastic waste and microplastics. This paper discusses the sampling and analysis of microplastic in different media, followed by spatial and temporal distribution of microplastics in marginal seas and coastal and freshwater systems. After summarizing the recent advances on toxicology research and risk assessment of microplastics, this paper provides suggestions for future study to provide baseline information for better risk assessment and improved understanding of the lifecycle of microplastics in the environment.

“…The massive occurrence of microplastics in water can have toxic effects on organisms and cause serious ecological risks [11][12][13]. Toxicity mainly comes from three pathways: (1) pressure of ingestion, such as physical blockages, energy consumption of ingestion; (2) leakage of plastic additives, such as plasticizers; (3) exposure to microplastic-related contaminants [12,14,15].…”

As a new type of pollutant, microplastics are an emerging scientific and social concern in the environment and are widely distributed in the aquatic environment and organism. Nowadays, researches on microplastic pollution mainly focus on the marine environment. As a bridge for the migration of microplastics from the terrestrial environment to the marine environment, the freshwater environment has been deserved more attention. Published articles on microplastics in freshwater environments were reviewed in this paper, and four typical behaviors of microplastics were summarized: biological ingestion, biological attachment, adsorption of pollutants and release of plasticizers. In addition, the progress in research and results on the ecological toxicity of microplastics to freshwater organisms was also analyzed. Finally, emphasis on future research on the toxicity of microplastics to freshwater aquatics organisms was made throughout this review as a tool in microplastic risk assessment research.
