“…Trophic transfer of microplastics, or an animal indirectly ingesting microplastics via its prey, has been demonstrated in the laboratory (Farrell and Nelson 2013;Setälä et al 2014), but our review suggests that few studies have looked for and (or) observed trophic transfer in the field (Furtado et al 2016;Hammer et al 2016). Nonetheless, even if trophic transfer does occur, we still do not know whether transferred plastic particles are excreted at higher trophic levels, or whether they bioconcentrate, bioaccumulate, and biomagnify (Fig.…”

“…Ten papers specifically expressed intentions in reviewing or reporting ingested plastics within biota at different trophic levels, but only three papers specifically tested the hypothesis that plastics were trophically transmitted ( Table 3). Two of the three tested trophic transfer in bird species (Furtado et al 2016;Hammer et al 2016) and the other in invertebrates (Remy et al 2015).…”

“…could include approaching plastic studies using trophic interaction methods as in Hammer et al (2016) and Remy et al (2015) or targeting species that have trophic connections during plastics studies (e.g., Furtado et al 2016). There has been much less work on plastic ingestion in the offshore regions (FAO fishing regions) with the most reported FAO regions being the East Central Pacific, the North East Pacific, the South East Atlantic and the South West Pacific (Fig.…”

Assessing plastic debris in aquatic food webs: what we know and don’t know about uptake and trophic transfer

et al. 2019

Plastic pollution is now recognized as a global environmental issue that can affect the health of biota and ecosystems. Now that a growing number of species and taxa are known to ingest a diverse range of sizes and types of plastics and retain the plastics in their guts, there are increasing questions relating to the movement of plastics through food webs, and how biota may directly and indirectly ingest plastics. Here, we synthesize what is known from the published, peer-reviewed literature about plastic ingestion by animals and identify critical gaps in our knowledge. We systematically reviewed and examined the literature for studies that reported ingested plastics in marine and freshwater biota at a global scale. Our objective was to inform discussions and future studies regarding what we know about plastic ingestion and fate in food webs. We assessed what regions, ecosystems, and food webs have been studied to date and whether potential information may already be available to assess if trophic transfer of plastics may be occurring. We found 160 relevant publications through 2016. Most studies were concentrated in specific regions and in specific ecosystem types, with freshwater studies being the most limited. Moreover, most studies examined one species at a time with only a handful of regions with multiple taxa examined across multiple studies. Twenty-one percent of the regions have no published data on plastic ingestion to date. Although some studies have measured ingestion in multiple species across trophic levels, few have tested the hypothesis that plastics are transferred across trophic levels. Moreover, none have addressed questions related to biomagnification. While our review suggests that numerous papers have recorded the ingestion of plastics by biota across many trophic levels, habitats, and geographic regions, many questions regarding how or whether biota retain, bioaccumulate, biomagnify, and trophically transfer plastics still need to be addressed.

“…Polyhydroxybutyrate (PHB) is one of the common biodegradable polymers, which has many excellent properties such as biodegradability, optical activity, biocompatibility, and UV resistance and behaves similarly to polypropylene. Therefore, PHB can be applied as a suitable material in food packaging and wound dressings, controlled drug delivery, and tissue engineering scaffolds . However, PHB and other polymers from polyhydroxyalkanoates family have poor mechanical and thermal properties, for example, low elongation and a narrow window of processability, which restricts their application, while poly(butyleneadipate‐ co ‐terephthalate) (PBAT) is an aliphatic and aromatic copolymer, which has excellent biodegradable properties from aliphatic polyesters and good mechanical properties from aromatic polyesters .…”

In this study, polyhydroxybutyrate/poly(butyleneadipate-co-terephthalate) (PHB/PBAT) nanofibrous membranes were produced by electrospinning the blends of biodegradable PHB and PBAT. The antibacterial hydrophobic nanofiber membranes were obtained by grafting 1-allylhydantoin and perfluorooctyl acrylate onto the PHB/PBAT membranes. The prepared nanofibrous membranes were chlorinated with chlorine bleach and characterized by scanning electron microscopy, Fourier transform infrared, and thermogravimetric analysis. The chlorinated nanofibrous membranes exhibited efficient antimicrobial activity against Escherichia coli O157:H7 (ATCC 43895) and Staphylococcus aureus (ATCC 6538) with 6.08 and 5.78 log reduction, respectively. The contact angle of this antibacterial membrane was 123.1°± 1.9°. The treated membranes showed good stability and durability towards UV-A light exposure and storage. To effectively block the entry of water and moisture and slow down food spoilage, food packaging materials need to be hydrophobic.Hydrophobic agents including wax, aluminum soap, zirconium soap, | ElectrospinningEight percent (wt) of PHB and PBAT (PHB/PBAT, 1:1, w/w) were dissolved in a mixture of CHCl 3 and DMF (CHCl 3 /DMF, 10:1, w/w).Electrospinning was performed at 20 kV with a flow rate of 1.5 mL·h −1 at ambient temperature. The distance from tip to collector was 15 cm. The electrospun fibrous membranes were collected on a rotating drum covered with an aluminum foil at a speed of 50 rpm. | Grafting AH and PFAThe mechanism scheme of AH and PFA grafting on PHB/PBAT surfaces is shown in Scheme 1. Initially, AH (1, 2, 3, 4, 5, 7, and 9 wt%) and AIBN (10 wt% of AH) were dissolved in ethanol solution in an ultrasonic bath for 20 minutes. Ethanol solution was at a bath ratio of 50:1 on the weight of fibrous membranes. Then, a certain amount of PHB/PBAT fibrous membranes was immersed in the above solution in a water bath at 75°C for 3 hours. Subsequently, fibrous membrane was extracted in ethanol for 24 hours using a Soxhlet extractor.Perfluorooctyl acrylate (3, 5, 7, 9, 11, and 13 wt%), AIBN (10 wt% of PFA), and OP-10 (2 wt% of PFA) were dissolved in ethanol solution by ultrasonic vibration for 20 minutes at room temperature. The PHB/PBAT fibrous membranes were added into the solution in a water bath at 75°C for 3 hours. Subsequently, fibrous membrane was extracted in ethanol for 24 hours using a Soxhlet extractor. | Chlorination and titrationThe PHB/PBAT-AH/PFA fibrous membranes were immersed in a 0.05% of NaOCl solution, pH 7, at ambient temperature for 1 hour to become an antimicrobial material. Then, the chlorinated fibrous membranes were washed thoroughly with deionized water and dried at 45°C for 1 hour to remove the unbound chlorine. The loaded active chlorine content on the membranes was measured by the modified iodometric/thiosulfate titration method. The chlorine weight percent of the membranes was calculated according to the equation below:where Cl + (%) is the weight percent of active chlorine on the sample; N and V are...
