“…Plastic debris of all sizes and densities will be fouled and colonized by microbes, forming biofilms, which can lead to significant changes in particle buoyancy. For instance, increased settling as a result of biofouling has recently been shown for marine particles [57,58,62], and it is plausible that the same holds for plastics in the freshwater environment (Fig. 2).…”

“…Advection, dispersion, diffusion, settling, and resuspension depend on particle properties such as size, density, shape, fractal dimension, and porosity [53][54][55]. During transport, the aforementioned particle properties can change due to aggregation or biofouling, which will further influence their fate [56][57][58]. Aggregation is usually modeled using a von Smoluchowski particle interaction model where the formation of aggregates is described kinetically as a function of the colliding particle concentrations, their sizes and densities, their collision frequencies, and attachment efficiencies [56,59,60].…”

“…Biofouling of plastics has been reported for freshwater samples [83,84] and also is a well-researched phenomenon in marine waters [57,58,62,84]. Plastic debris of all sizes and densities will be fouled and colonized by microbes, forming biofilms, which can lead to significant changes in particle buoyancy.…”

Contamination with plastic debris has been recognized as one of today's major environmental quality problems. Because most of the sources are land based, concerns are increasingly focused on the freshwater and terrestrial environment. Fate and transport models for plastic debris can complement information from measurements and will play an important role in the prospective risk assessment of plastic debris. We review the present knowledge with respect to fate and transport modeling of plastic debris in freshwater catchment areas, focusing especially on nano-and microplastics. Starting with a brief overview of theory and models for nonplastic particles, we discuss plastic-specific properties, processes, and existing mass-balance-, multimedia-, and spatiotemporally explicit fate models. We find that generally many theoretical and conceptual approaches from This chapter has been externally peer reviewed.The original version of this chapter was revised. An erratum to this chapter can be found at DOI 10.1007/978-3-319-61615-5_14. models developed earlier for other types of (low density) particles apply also to plastic debris. A unique feature of plastic debris, however, is its combination of high persistence, low density, and extremely wide size distribution, ranging from the nanometer to the >cm scale. This causes the system behavior of plastic debris to show a far wider variety than most other materials or chemicals. We provide recommendations for further development of these models and implications and guidance for how fate and transport models can be used in a framework for the tiered risk assessment of plastic debris.

“…Instead of pure ZnCl 2 solution, we used a liquid that was a 50/50% mix of ZnCl 2 and CaCl 2 solutions. The obtained liquid specific density was 1.48 ± 0.05 g mL −1 , which allows for separation of the most part of pure plastics (Chubarenko et al ), even affected by biofouling. Our experiments showed that this solution was stable: crystallization did not appear during 6 months under normal laboratory conditions at temperature of about 20°C.…”

“…Specific density of MPs can vary significantly depending on a polymer type, technological processes of its production, additives, weathering, and biofouling (More't‐Ferguson et al ; Chubarenko et al ). Intact and raw plastics can either sink or float on the sea surface, but with time, most of floating plastics become negatively buoyant as well due to biofouling or adherence of denser particles, and sink to the seafloor (More't‐Ferguson et al ; Lobelle and Cunliffe ).…”

The Munich Plastic Sediment Separator (MPSS), proposed by Imhof et al. (), showed its high efficiency in extracting microplastics (MPs) from natural sediment samples preliminarily cleaned and then enriched by MPs in laboratory. We tested the efficiency of the MPSS, assembled at the Atlantic Branch of P.P.Shirshov Institute of Oceanology (Kaliningrad), using unprepared natural bottom deposits of different types collected in the Baltic Sea. The tests that were performed included spikes of sediments with artificial reference particles (ARPs) and the sediment samples analyses with two separate methods of extraction and determination of MPs content in residuals of MPSS. While the ARP extraction efficiency from natural sediments by the MPSS was really high (97.1% ± 2.6%; p = 0.05; n = 14; confidence interval, t‐distribution), the extraction efficiency of marine MPs was considerably lower (13–39%) than that obtained with a modification of the method previously published by NOAA. The remaining marine MPs were found in the spoil dump and in the bulk solution fractions of the separator, indicating that MPs were not perfectly cleaned from sediment particles, probably, due to presence of organic matter. It is concluded that the MPSS application for quantitative MPs analysis requires further testing and elaboration of standardized extraction procedures.
