“…Their chemical composition was similar to the results of previous studies conducted on soils from the same area, suggesting that the MPs present in the soils are leaching into the GW [121]. The second study detected fewer MP particles, with results ranging from 0.006 to 0.193 MP/L [112]. The highest MP concentrations were detected at the lowest altitude points, suggesting that the distance between the surface and the aquifer may be a factor in the entry of MPs into the GW [112].…”

“…Consequently, studies assessing the occurrence of MPs in GW are difficult to compare as they use different sampling and analytical approaches [15]. In addition, a multitude of factors can contribute to the variations in the number of MPs detected in GW across different studies, e.g., population density [109], climatology, hydrology, geology, land use of the study area [110], the presence of a particular source of contamination [111], and the distance between the surface and the aquifer [112].…”

“…A minimum sample size of five hundred litres is necessary to ensure reliable results [15,119,120]. However, only two studies, both from Korea, sampled this many litres or more directly from GW [112,121]. These studies were conducted in a fractured rock aquifer and showed differences in the number of MPs detected.…”

Microplastics (MPs), defined as plastic particles measuring less than 5 mm, are considered an emerging pollutant. Their presence in the water cycle and their interaction with ecological processes pose a significant environmental threat. As groundwater (GW) represents the primary source of drinking water, monitoring MPs in GW and investigating their potential sources and pathways is of urgent importance. This article offers a comprehensive overview of the primary contamination pathways of MPs from surface water, seawater, and soil into the GW. Moreover, it presents an examination of the occurrence of MPs in GW and identifies the challenges associated with their monitoring in GW. This study also discusses the difficulties associated with comparing research results related to MPs in GW, as well as indicating the need for implementing standardised techniques for their sampling and detection. On the basis of our experience and the literature review, we highlight the importance of understanding the specific hydrogeological and hydrogeographic conditions, collecting representative samples, using sampling devices with comparable specifications and comparable laboratory techniques for MP identification, and preventing contamination at all stages of the monitoring process. This review offers valuable insights and practical guidelines on how to improve the reliability and comparability of results between studies monitoring MPs in GW.

“…Additionally, previous studies have shown that grab sampling, which involves using bottles to collect seawater samples ranging from 1 to 10 L in volume, yields MP concentrations 3 orders of magnitude higher than net sampling. , This difference arises because the concentration of low-volume samples is often several orders of magnitude higher than that of large-volume samples, and smaller particles may be entirely missed during sampling . Therefore, a size-independent MP separation method is urgently needed. − …”

Marine microplastic (MP) pollution has aroused growing public concern. Reliable analytical techniques are required to assess the extent of MP pollution. However, the detection of MPs is hindered by the challenge of separating them from complex environmental substrates. Herein, a simple and quick method to collect MPs from flowing seawater was proposed using a two-phase (tributyl phosphate (TBP)–water) system. The method can be used to efficiently and continuously separate multiple sizes of MPs at different depths. Due to the hydrophobicity of MPs, most of them would be collected at the two-phase interface. At the same time, due to the formation of MP–oil aggregates and the effect of buoyancy, very few MP–oil aggregates that enter the water phase return to the two-phase interface. Results from laboratory experiments revealed that the average recovery rate of the seven types of MPs (polypropylene, polyethylene terephthalate, polyvinyl chloride, polyamide 66, polycarbonate, polystyrene, and polyethylene) reached 95.67% ± 0.47%. Furthermore, this method was successfully employed to collect MPs from different seawater depths in Zhanjiang Bay, demonstrating its efficiency under real-world conditions. This method offers a novel approach for efficiently collecting MPs from flowing water with a high enrichment efficiency.
