“…Bottom is a summary of ANCOVA of the effects of abiotic particle type and proportion of abiotic particles in suspension on CR. Our observations of normal CR in low MP concentrations are consistent with previous reports that mussels readily filter and ingest MP in natural settings (e.g., Li et al 2015Li et al , 2016Renzi et al 2018). Asterisk (*) indicates statistical significance (p < 0.05).…”

In coastal habitats, mussels are exposed to microplastics (MP; plastic 0.1 μm–5 mm) and silt, two abiotic particles that are similarly sized and lack nutrition. The addition of MP or silt may change the functional response of mussels. We measured clearance rate (CR) of Mytilus trossulus in three particle treatments (algae, MP + algae, and silt + algae) across four concentrations to (1) determine if the effects of MP and silt are similar and (2) disentangle the effects of particle type, particle concentration, and proportion of abiotic particles. CR decreased by 62% at high MP concentrations (> 1250 particles mL−1) but was not affected at equivalent silt concentrations. These findings suggest high MP concentrations inhibit mussel CR, more than expected by changes in particle concentration or the proportion of abiotic particles. As plastic production increases, mussel exposure to MP will increase, potentially reducing energy transfer, benthic‐pelagic coupling, and water clarity.

“…The levels of microplastic pollution in the clams from Taihu Lake (0.2e12.5 items/g ww) were similar to those in bivalves from China (0.9e10.5 items/g) (Li et al, 2015a(Li et al, , 2016. In a worldwide comparison, these bivalves have been classified as highly polluted organisms by microplastics (Li et al, 2015a(Li et al, , 2016. The average level of microplastics in Taihu Lake clams was much higher than that in bivalves (0.36 items/g) cultured for human consumption (Van Cauwenberghe and Janssen, 2014).…”

“…The final number of microplastics was recalculated by removing the verified nonplastics. The microplastics were classified into four morphotypes: fiber, pellet, film and fragment (Li et al, 2016). A fiber was defined as a microplastic with a slender and greatly elongated appearance; pellets were round microplastic with a spherical shape; a film was a small and very thin layer or a piece of large plastic debris; a fragment was an isolated or incomplete part of large plastic debris.…”

“…Evidence is mounting that fibers are a dominant form of plastic pollution in many aquatic ecosystems-especially fluvial (McCormick et al, 2014;Zhao et al, 2014;Dris et al, 2015;Baldwin et al, 2016), but also in marine beaches and sediment (Browne et al, 2011;Claessens et al, 2011;Woodall et al, 2014;Fischer et al, 2015;Naidoo et al, 2015;. The ecological implications of these fibers remain to be shown, but plastic fibers are increasingly found in the stomachs and tissues of aquatic wildlife, many of which are consumed by larger animals, including humans (Neves et al, 2015;Rochman et al, 2015a;Vandermeersch et al, 2015;Li et al, 2016). Direct human health impacts have been reported, as well: when inhaled, microplastic fibers are retained the lung tissues and can become associated with malignant tumors (Pauly et al, 1998).…”

Distribution and Modeled Transport of Plastic Pollution in the Great Lakes, the World's Largest Freshwater Resource

Most plastic pollution originates on land. As such, freshwater bodies serve as conduits for the transport of plastic litter to the ocean. Understanding the concentrations and fluxes of plastic litter in freshwater ecosystems is critical to our understanding of the global plastic litter budget and underpins the success of future management strategies. We conducted a replicated field survey of surface plastic concentrations in four lakes in the North American Great Lakes system, the largest contiguous freshwater system on the planet. We then modeled plastic transport to resolve spatial and temporal variability of plastic distribution in one of the Great Lakes, Lake Erie. Triplicate surface samples were collected at 38 stations in mid-summer of 2014. Plastic particles >106 µm in size were quantified. Concentrations were highest near populated urban areas and their water infrastructure. In the highest concentration trawl, nearly 2 million fragments km −2 were found in the Detroit River-dwarfing previous reports of Great Lakes plastic abundances by over 4-fold. Yet, the accuracy of single trawl counts was challenged: within-station plastic abundances varied 0-to 3-fold between replicate trawls. In the smallest size class (106-1,000 µm), false positive rates of 12-24% were determined analytically for plastic vs. non-plastic, while false negative rates averaged ∼18%. Though predicted to form in summer by the existing Lake Erie circulation model, our transport model did not predict a permanent surface "Lake Erie Garbage Patch" in its central basin-a trend supported by field survey data. Rather, general eastward transport with recirculation in the major basins was predicted. Further, modeled plastic residence times were drastically influenced by plastic buoyancy. Neutrally buoyant plastics-those with the same density as the ambient water-were flushed several times slower than plastics floating at the water's surface and exceeded the hydraulic residence time of the lake. It is likely that the ecosystem impacts of plastic litter persist in the Great Lakes longer than assumed based on lake flushing rates. This study furthers our understanding of plastic pollution in the Great Lakes, a model freshwater system to study the movement of plastic from anthropogenic sources to environmental sinks.
