“…Notable histological changes and a strong inflammatory response were observed upon the uptake of micro high-density polyethylene (HDPE) by blue mussel Mytilus edulis L. (von Moos et al 2012). Setälä et al (2014) experimentally proved that microplastics can be transferred into higher trophic level organisms via food chain.…”

Presence of plastic debris in marine and freshwater ecosystems is increasingly reported. Previous research suggested plastic debris had a strong affiliation for many pollutants, such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and heavy metals. In this study, the sorption behavior of pharmaceuticals and personal care products (PPCPs), including carbamazepine (CBZ), 4-methylbenzylidene camphor (4MBC), triclosan (TCS), and 17α-ethinyl estradiol (EE2), to polyethylene (PE) debris (250 to 280 μm) was investigated. The estimated linear sorption coefficients (K d ) are 191.4, 311.5, 5140, and 53,225 L/kg for CBZ, EE2, TCS, and 4MBC, and are related to their hydrophobicities. Increase of salinity from 0.05 to 3.5 % did not affect the sorption of 4MBC, CBZ, and EE2 but enhanced the sorption of TCS, likely due to the salting-out effect. Increase of dissolved organic matter (DOM) content using Aldrich humic acid (HA) as a proxy reduced the sorption of 4MBC, EE2, and TCS, all of which show a relatively strong affiliation to HA. Results from this work suggest that microplastics may play an important role in the fate and transport of PPCPs, especially for those hydrophobic ones.

“…Plausible mechanisms for the deposition of low-density polymers in submerged sedimentary environments include net density increase of microplastic particles by biofouling (e.g. Ye and Andrady, 1991;Andrady, 2011;Zettler et al, 2013;McCormick et al, 2014), adsorption of natural substances to the surface (Frias et al, 2016), inclusion of inorganic fillers during manufacturing and faecal express (Cole et al, 2013;Setälä et al, 2014;Zalasiewicz et al, 2015). Inorganic fillers were not identified in any of the Raman spectra of the particles identified as PE and PP in this study, however, many microplastics in our study, particularly those with irregularly shaped, textured or degraded surfaces, appeared to have claylike particles adhered to their surfaces.…”

Microplastics contamination of Lake Ontario sediments is investigated with the aim of identifying distribution patterns and hotspots in nearshore, tributary and beach depositional environments. Microplastics are concentrated in nearshore sediments in the vicinity of urban and industrial regions. In Humber Bay and Toronto Harbour microplastic concentrations were consistently >500 particles per kg dry sediment. Maximum concentrations of ~28,000 particles per kg dry sediment were determined in Etobicoke Creek. The microplastic particles were primarily fibres and fragments < 2 mm in size. Both low-and high-density plastics were identified using Raman spectroscopy. We provide a baseline for future monitoring and discuss potential sources of microplastics in terms of how and where to implement preventative measures to reduce the contaminant influx. Although the impacts of microplastics contamination on ecosystem health and functioning is uncertain, understanding, monitoring and preventing further microplastics contamination in Lake Ontario and the other Great Lakes is crucial . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 Ballent, Anika Manuscript page 1Sources and sinks of microplastics in Canadian Lake Ontario nearshore, tributary and beach sediments.

“…Perry et al (2013) found a "ball" of nylon fishing line in little auk that was inside the stomach of a fish. Trophic transfer of microplastics has been demonstrated experimentally in several species ranging from zooplankton to larger invertebrates to fish (Setälä et al, 2014;Farrell & Nelson, 2013;Batel et al, 2016).…”
