“…Previous estuarine field studies documented microplastic ingestion in zooplankton (Payton 2017), bivalves (Santana et al 2016;Leslie et al 2017), gastropods (Leslie et al 2017), crustaceans (Devriese et al 2015;Leslie et al 2017), and juvenile and adult fishes of various feeding guilds (Ferreira et al 2016;Vendel et al 2017). Among these studies, the number of ingested microplastics ranged from 0.009 ± 0.004 microplastics/ individual in zooplankton (Payton 2017) to 25.9 microplastics/ individual in the Acoupa weakfish, Cynoscion acoupa (Ferreira et al 2016), and included a variety of shapes, colors, and polymer types.…”

Recent research indicates that microplastic (<5 mm) ingestion may impact the immune function of marine and aquatic organisms at the tissue and cellular levels; however, their susceptibility to disease following exposure has not been directly investigated. The objective of the present study was to directly evaluate the impact of microplastic ingestion on the susceptibility of the grass shrimp Palaemonetes pugio to bacterial infection with Vibrio campbellii. Grass shrimp were exposed to one of several particle treatments (natural sediment, polyethylene spheres, polypropylene fragments, tire fragments, and polyester fibers) or particle‐free water for 96 h at a nominal concentration of 50 000 particles/L prior to a bacterial challenge with V. campbellii. No significant mortality was observed among any of the particle types during the 96‐h particle exposure. The survival of grass shrimp following V. campbellii challenge did not vary significantly among shrimp exposed to particle‐free water, sediment, polyethylene spheres, polypropylene fragments, tire fragments, and polyester fibers. Grass shrimp cleared the majority of ingested particles and all the ventilated particles within 48 h. The present study shows that microplastic ingestion did not alter the susceptibility of grass shrimp to bacterial infection, and also provides depuration rates for a variety of microplastic shapes and polymer types that were previously lacking. This information increases our understanding of the size‐ and shape‐dependent effects of microplastic ingestion. Environ Toxicol Chem 2019;38:2233–2242. © 2019 SETAC.

“…Single or staggered open sieve constructions, as well as encapsulated flow-through filtration devices are approaches that have been utilised by other studies [9][10][11]. Additionally, sampling of MP has been accomplished by means of density separation in continuous flow centrifuges used in suspended matter analysis [12].…”

A variety of microplastic sampling instrumentation is currently used for water pollution studies. Plankton net-based approaches have been the most adopted techniques for water column and surface sampling. When applied to microplastics (MP) in the lower µm size range these methods, however, introduce non-negligible risks of sample contamination and loss due to instrument and procedure design. Based on the first principles of systems engineering design we have developed a mobile sampling platform for field application that fulfils the needs of producing usable MP samples with a lower size limit of 10 µm using an encapsulated flow-through filtration concept. Here, we explain the requirements, development, and construction of the device for others to replicate and improve.

“…Over the ensuing decades we have learned that synthetic fibers also originate from atmospheric deposition (Baldwin et al, 2016;Dris et al, 2016). With this discovery, and further elucidation of other sources of plastic pollution, the ability to identify microplastic sources from environmental samples has come under increasing scrutiny (Leslie et al, 2017).…”

“…Research papers assessing the provenance of microplastics in environmental samples have reported a wide range of confidence in their ability to attribute sources. Some reports have stated that locating the source of plastics from environmental samples is impossible, or that there is a high level of uncertainty in the assessment (Claessens et al, 2011;Leslie et al, 2017;Woodall et al, 2014). Other reports state with confidence that the microplastics they observed in the environment originated from wastewater effluent (Estahbanati & Fahrenfeld, 2016;Vermaire et al, 2017;Warrack et al, 2018), or not (Campbell et al, 2017).…”
