“…Whilst there is little doubt over the enormity of plastic and MP pollution in scale, the vast majority of research has concentrated on marine environments whilst neglecting other ecosystems (Redondo-Hasselerharm et al, 2018;Wagner and Lambert, 2018). To date there is a paucity of information on the impacts of MPs in freshwater ecosystems, despite the broad range of pathways through which MPs can proliferate (Mason et al, 2016), and the extensive range of species which actively ingest MPs in these systems (Canniff and Hoang, 2018;Imhof et al, 2016Imhof et al, , 2013Nel et al, 2018;Qu et al, 2018).…”

Microplastics (MPs) continue to proliferate and pollute aquatic and terrestrial environments globally. The impacts of MP pollution on ecosystems and their functioning remain poorly quantified, with most research hitherto focusing on marine ecosystems. There is a paucity of information on the impacts of MPs in freshwater ecosystems, despite the broad range of pathways through which MPs can proliferate and the extensive range of species which actively ingest MPs in these systems. Of particular interest are organisms that bridge aquatic and terrestrial habitats. The present study thus examines the uptake, ontogenic transference and effect of different concentrations (0, 50, 100 and 200 MPs mL-1) and sizes (2 and 15 µm) of polystyrene MPs between aquatic and terrestrial life stages of Culex pipiens complex mosquitoes. Both 2 and 15 µm MPs transferred from the aquatic larval to terrestrial adult stage of Culex mosquitoes, and uptake correlated tightly with initial exposure concentration. However, neither concentration nor size of MPs significantly influenced mortality rates between the aquatic larval and terrestrial adult stage. There was also no impact of MPs on the weight of emerging mosquito adults. We thus demonstrate that MPs can be transferred ontogenically through organisms with complex life histories, presenting a potential pathway for dispersal of MPs into terrestrial environments. We also show that MPs exposure does not affect mortality rates between life stages of freshwater Culex populations. This suggests that MPs do not impact nutritional uptakes, with unhampered development to adulthood facilitating subsequent dispersal of MPs aerially and between freshwater and terrestrial habitats.

“…In a following study, Li et al (2016) collected mussels along China's coastlines at 22 sites, and found the average microplastic concentration in mussels to be 1.5-7.6 items/individual, among which wild groups had higher concentration than farmed groups. Qu et al (2018) found a positive linear relationship between microplastic concentration in water and mussels collected from the field. Kolandhasamy et al (2018) observed that microfibers adhered to foot and mantle of mussels, another way in which microplastics can contact tissues of the bivalves.…”

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.

“…Numerous measures were taken to minimize procedural contamination, but as with other studies (e.g., Li et al 2015;Davidson and Dudas 2016;Qu et al 2018;Su et al 2018) it was not completely eliminated. Contamination in procedural controls (4.91 AE 1.11), microscope blanks (0.20 AE 0.03), and, for razor clams, a secondary digestion and separation step (1.0 AE 0.0) was quantified (Supporting Information Appendix 2).…”

“…Average microplastic length detected as contamination (n = 124) for all sample types was 1.67 AE 0.11 mm, and most frequently detected colors in blanks and controls were colorless (79%) and blue (10%). As with multiple other studies (e.g., Li et al 2015Li et al , 2016Li et al , 2018aDavidson and Dudas 2016;Qu et al 2018;Su et al 2018;Rochman et al 2019), we report microplastics detected in blank samples (Supporting Information Appendix 2), rather than performing a blank-subtraction on environmental results since controls were intended to provide a range of possible contamination levels introduced through laboratory procedures. As such, our reported numbers are estimated maximum possible microplastic concentrations.…”

“…Microplastics may also sorb harmful contaminants that, once ingested or incorporated in tissues, are released into the organism (Teuten et al 2007(Teuten et al , 2009. In some studies, environmental microplastic concentrations have been directly correlated with microplastic burdens in coastal bivalves (Mathalon and Hill 2014;Li et al 2016;Qu et al 2018;Hantoro et al 2019).…”

Microplastics are an ecological stressor with implications for ecosystem and human health when present in seafood. We quantified microplastic types, concentrations, anatomical burdens, geographic distribution, and temporal differences in Pacific oysters (Crassostrea gigas) and Pacific razor clams (Siliqua patula) from 15 Oregon coast, U.S.A. sites. Microplastics were present in organisms from all sites. On average, whole oysters and razor clams contained 10.95 ± 0.77 and 8.84 ± 0.45 microplastic pieces per individual, or 0.35 ± 0.04 pieces g−1 tissue and 0.16 ± 0.02 pieces g−1 tissue, respectively. Contamination was quantified but not subtracted. Over 99% of microplastics were fibers. Material type was determined using Fourier‐transform infrared spectroscopy. Spring samples contained more microplastics than summer samples in oysters but not razor clams. Our study is the first to document microplastics in Pacific razor clams and provides important coast‐wide data to compare microplastic burden across species, seasons, and sites.
