“…MP concentrations in these small lakes in densely populated Italy were higher than in large Lake Kallavesi, which lies in a less populated area. Relatively high concentrations were also found in Hungarian surface waters of natural and excavated lakes (3.52–32.05 MPs/m 3 , 100 μm–2 mm particles) (Bordos et al, ). This result is higher than our mean pump filtration concentration for >100 μm particles.…”

“…Most of the previous MP studies of lake surface waters have not utilized spectroscopic methods and do not provide information about chemical composition. However, in Hungarian freshwaters PE, PP, PS, and polyester were the most common polymer types (Bordos et al, ). Additionally, in Lake Superior, the United States, the most common polymers were PE, PET, PVC, and PP, analyzed with FTIR (Hendrickson, Minor, & Schreiner, ).…”

“…In the future, the filter combinations could be adjusted for filtering larger volumes by changing the smallest pore size to, for example, 50 μm, or using 100/50/20 μm filter set for collecting small particles. We used plankton net filters made from nylon, but stainless steel filters have also been used for freshwater sampling (Bordos et al, ).…”

“…To date, MPs have been studied in surface waters, for example, in Laurentian Great Lakes of the United States (Eriksen et al, ), Lake Winnipeg in Canada (Anderson et al, ), Lake Hovsgol in Mongolia (Free et al, ), and Taihu Lake in China (Su et al, ). In Europe, microplastics of lake surface waters have been studied in Swiss (Faure, Demars, Wieser, Kunz, & Alencastro, ) and Italian lakes (Fischer, Paglialonga, Czech, & Tamminga, ), and in Hungarian natural and excavated lakes (Bordos et al, ).…”

We examined microplastic concentrations, size distributions, and polymer types in surface waters of a northern European dimictic lake. Two sampling methods, a pump sieving water onto filters with different pore sizes (20, 100, and 300 µm) and a common manta trawl (333 µm), were utilized to sample surface water from 12 sites at the vicinity of potential sources for microplastic emissions. The number and polymer types of microplastics in the samples were determined with optical microscopy and μFTIR spectroscopy. The average concentrations were 0.27 ± 0.18 (mean ± SD) microplastics/m 3 in manta trawled samples and 1.8 ± 2.3 (>300 μm), 12 ± 17 (100-300 μm) and 155 ± 73 (20-100 μm) microplastics/m 3 in pump filtered samples. The majority (64%) of the identified microplastics (n = 168) were fibers, and the rest were fragments. Materials were identified as polymers commonly used in consumer products, such as polyethylene, polypropylene, and polyethylene terephthalate. Microplastic concentrations were high near the discharge pipe of a wastewater treatment plant, harbors, and snow dumping site. • Practitioner points• Samples were taken with a manta trawl (333 μm) and a pump filtration system (300/100/20 μm) • With pump filtration, small 20-300 μm particles were more common than >300 μm particles • The average concentration of manta trawled samples was 0.27 ± 0.18 (mean ± SD) microplastics/m 3 • FTIR analysis revealed PE, PP, PET, and PAN to be the most common polymers •

“…The fact that MPs can enter various aquatic organisms at different trophic levels has been well-established by different studies [28,45,[76][77][78][79][80][81][82]. The two main routes of MPs uptake are respiration and ingestion [83].…”

Microplastic Contamination in Freshwater Environments: A Review, Focusing on Interactions with Sediments and Benthic Organisms

Plastic is one of the most commonly produced and used materials in the world due to its outstanding features. However, the worldwide use of plastics and poor waste management have led to negative impacts on ecosystems. Plastic degradation in the environment leads to the generation of plastic particles with a size of <5 mm, which are defined as microplastics (MPs). These represent a global concern due to their wide dispersion in water environments and unclear potential ecotoxicological effects. Different studies have been performed with the aim of evaluating the presence and impacts of MPs in the marine environment. However, the presence of MPs in freshwater systems is still poorly investigated, making data retrieval a difficult task. The purpose of this review is to identify the main aspects concerning MPs pollution sources in lakes and rivers, with a focus on freshwater sediments as a site of accumulation and as the habitat of benthic organisms, which are key components of food webs and play a fundamental role in energy/contaminant transfer processes, but are still poorly considered. Through this review, the sources and fate of MPs in freshwater are analysed, ecotoxicological studies focused on sediments and benthic fauna are exposed, the most frequently used sampling and analysis strategies are reported, and future trends of MPs analysis in this field are proposed.
