Decades of conservation efforts and legal ... Alfonso, M. B. et al. First evidence of microplastics in nine lakes across Patagonia (South America). Sci. Total Environ. 733, …The amount of microplastics in lakes and soils could rival the more than 15 trillion tons of particles thought to be floating in the ocean’s surface alone. Credit: Amanda Montañez; Source ...Microplastics have been predominantly studied in marine environments compared to freshwater systems. However, the number of studies analyzing microplastic concentrations in water and sediment within lakes and rivers are increasing and are of utmost importance as freshwaters are major pathways for plastics to the oceans.Lakes are the greatest reserve of available superficial inland fresh water and concurrently one of the most threatened ecosystems. Among the many pollutants, …Feb 1, 2022 · Seas/oceans, rivers, and lakes are considered as different environmental compartments (Fig. 1 b), for the fate and transport of microplastics (Fig. 1 c) in water environments. Consequently, 51 articles are found and 36 of them are fully reviewed, depending on the different aspects of the modeling methodologies they adopt. Microplastics are an environmental contaminant of growing concern, but there is a lack of information about microplastic distribution, persistence, availability, and biological uptake in freshwater systems. This is especially true for large river systems like the Colorado River that spans multiple states through mostly rural and agricultural land use. This study characterized the quantity and ...Microplastics in Taihu Lake, China. ☆. Microplastic reached 0.01 × 10 6 –6.8 × 10 6 items/km 2 in plankton net samples in Taihu Lake. There were 3.4–25.8 items/L in surface water and 11.0–234.6 items/kg dw in sediments. Microplastic distribution in plankton net samples was different from that in sediments.Blue Lakes project includes an educational school programme dedicated to schools of the main municipalities of Lake Garda, Bracciano and Trasimeno.. The educational school programme involves students in awareness-raising activities, concerning the problem of microplastics, and increasing their action capability in lakes protection, also …Microplastic densities were log-transformed to satisfy the assumption of normality. Finally, we compared densities of microplastics in Lake Winnipeg to those reported in the Great Lakes (Eriksen et al., 2013, their Table 1) using a Kruskal-Wallis test on ranks followed by Dunn's test for multiple comparisons with a Bonferroni adjustment.The rapid increases in microplastics in urban lake sediments | Scientific Reports Article Open access 21 January 2020 The rapid increases in microplastics in urban lake sediments Mingtan Dong,...Lakes are the greatest reserve of available superficial inland fresh water and concurrently one of the most threatened ecosystems. Among the many pollutants, plastics contaminate lakes worldwide; notwithstanding that, little is known on the impacts of macroplastics.
