“…The use of worn sampling equipment (nylon nets, pump systems, etc.) made of polymer materials such as PVC, PTFE, PE, PP, and PVDF leads to the release of MPs from the equipment into the sample [72,73]. It is necessary to perform field and procedural blanks to assess the effect of cross-contamination on the final test result.…”

The continuous growth in the production, unsustainable use, and disposal of plastics in recent decades has led to the emergence of a new type of pollutant, microplastics (MPs). In this article, the focus is on the form of MPs, which are produced by the fragmentation of textile fibres during washing processes. The problems associated with the characterisation and quantification of MPs in this type of sample are related to the wide range of concentrations, forms, and degree of degradation as well as physico-chemical and biological properties. Although the basic principles for the analysis of microplastics present in the environmental samples are known, there is the lack of standardised methods for the analysis of MPs in laundry effluents and domestic washing. Therefore, the continuous development of sophisticated analytical techniques and methodologies is required for the reliable collection and isolation, quantification, and characterisation of one of the most challenging analytes. The aim of this review is to outline the key steps of MPs analysis in laundry effluents and domestic washing, focusing on those steps that are underestimated in the current literature: sampling and sample preparation for analysis. Precisely these analytical steps, which can become the main source of analytical measurement system errors, ensure the quality of the analysis. This paper emphasises the importance of monitoring background contamination and presents guidelines to ensure quality control specifically for this type of analyte.

“…The MUMI sampler is a newly developed sampling methodology with an operation similar to the manta trawl, but the MUMI sampler allows unique filters for each sampling. The filters used in the study of Montoto-Martínez et al (2022) were 5 mm, 200 μm, and 20 μm. The UFO is a pump filtering sample collecting system developed by Aalborg University.…”

Following the alarming reports of microplastic pollution in the marine environment, increased attention has been given to microplastics in other environmental media. Despite the attention, there is limited information on the effects of microplastics distribution in freshwater systems. Further, because the size of microplastics varies widely in the environment, the commonly used sampling devices are not suitable for selectively extracting microplastics without causing cross-contamination. Thus, we developed a suitable device for microplastics of size 5-20 µm and studied microplastics distribution in freshwater at various depths by considering various types of microplastics and aqueous systems. Lake and river, two major water sources in South Korea, were selected for the study of microplastics distribution in water system. The microplastics distribution characteristics in both water systems showed that polypropylene and polyethylene were the most abundant across all depths because of their production volume. Plastic types with higher density were found only at the lower layers, and polystyrene was found in the upper layers because of the environmental effects on its buoyancy caused pore diameter and surface area. The lake and river had higher microplastics distribution in the lower layer and upper layer, respectively. This was because the ow rate in river was higher than that of lake. The higher ow rate reduced the settling velocity in river. Thus, hydrodynamic stability in uences the vertical distribution and concentrations of microplastics in the water systems. These results are expected to be used for understanding the behavioral characteristics of microplastics in water systems and to manage water sources.
