“…As such, coastal ecosystems are particularly susceptible to MP accumulation. A review article by Li et al [12] suggested sewage discharge, aquaculture, atmospheric deposition, and surface runoff as some of the main sources of MP pollution in coastal waters.…”

Due to the prevalence of plastic pollution in coastal ecosystems, aquatic organisms are at high risk for accumulating microplastics (MPs). Filter-feeding bivalves, such as mussels and oysters, may be exposed to, and subsequently accumulate, MPs due to the high volume of water they pass through their bodies. This study assessed the levels of MPs within Atlantic ribbed mussels (Geukensia demissa), a common filter feeder found along the United States Atlantic Coast, from 12 sites within Rehoboth Bay, Indian River Bay, and Little Assawoman Bay, collectively known as the Delaware Inland Bays. Composited mussels from each site were digested using potassium hydroxide and filtered. Microplastics were physically identified, sorted based on color, and counted using a digital microscope. Microplastics, almost entirely dominated by synthetic microfibers, were found in all mussels well above laboratory blanks. Across all sites, 40% of microfibers were black, and 27% of fibers were clear. The composite concentrations of MPs ranged from 0.25 to 2.06 particles/g wet tissue, with a mean of 0.08 ± 0.06. In general, higher concentrations were found in mussels collected at sites that were adjacent to more urbanized land use versus those from rural sites. At two sites, individual mussels, in addition to composites, were analyzed and had MP concentrations ranging from 11 to 69 particles/mussel. This study represents the first evaluation of MPs in this ecologically important coastal species and suggests its viability as a biomonitoring species for microplastic pollution.

“…They may also be airborne, and sewage treatment plants are also a substantial source (Eerkes-Medrano et al, 2015;Habib et al, 2020;Kumar et al, 2021;Uddin et al, 2021). Due to their small size, MPs can easily invade the marine food web and be ingested by a wide range of marine organisms and eventually by humans (Li et al, 2022). Exposure to MPs may cause oxidative stress, cytotoxicity, neurotoxicity, and immune system disruption in humans (Thiele et al, 2021).…”
