Bioaccumulation, transfer, and impacts of microplastics in aquatic food chains

Journal of Environmental Exposure Assessment, Journal Year: 2024, Volume and Issue: 3(3)

Plastics have become a pervasive global contaminant since the mid-20th century, causing harm to organisms at all levels. Preventative measures reduce plastic pollution and awareness-raising campaigns about damaging effects of debris on environment its inhabitants are crucial; however, most assessments focus singular trophic Microplastics, tiny particles ranging from 25 μm 5 mm, emerged as widespread form found in ecosystems worldwide. They can enter directly or through breakdown larger thought be mistaken for food by foraging animals. This leads microplastics circulating via direct indirect consumption, ultimately impacting even higher-order predators. Here, we assess impacts Chlorophyll concentrations, algal community structure, copepod survivorship, fish behavior experimental trials, addition simulated top-predator success plastic-exposed fish. Our results indicate that detrimental growth survival. We also observed transmission small spheres copepods predators, highlighting concerning pathway microplastic within aquatic ecosystems, where consumed plastics means. Primary consumers, like copepods, face dual pressures top-down forcing, they preferred over sources, bottom-up resource depletion, supplies limited exposure. findings demonstrate system-wide occur when included chains underscore urgent need comprehensive strategies mitigate entry into ecosystems.

Zoop to poop: assessment of microparticle loads in gray whale zooplankton prey and fecal matter reveal high daily consumption rates

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

The ocean continues to be a sink for microparticle (MP) pollution, which includes microplastics and other anthropogenic debris. While documentation of MP in marine systems is now common, we lack information on rates ingestion by baleen whales their prey. We collected assessed loads zooplankton prey fecal samples gray ( Eschrichtius robustus ) feeding coastal Oregon, USA produced the first estimates whale consumption from empirical data (i.e., not modeled). All species examined were documented items Atylus tridens, Holmesimysis sculpta, Neomysis rayii contained an average 4 per gram tissue, mostly microfiber morphotype. extrapolated estimate daily pregnant lactating whales, ranged between 6.5 21 million MP/day.

Baleen–Plastic Interactions Reveal High Risk to All Filter-Feeding Whales from Clogging, Ingestion, and Entanglement

Oceans, Journal Year: 2024, Volume and Issue: 5(1), P. 48 - 70

Published: Feb. 1, 2024

Baleen whales are ecosystem sentinels of microplastic pollution. Research indicates that they likely ingest millions anthropogenic microparticles per day when feeding. Their immense prey consumption and filter-feeding behavior put them at risk. However, the role baleen, oral filtering structure mysticete whales, in this process has not been adequately addressed. Using actual baleen tissue from four whale species (fin, humpback, minke, North Atlantic right) flow tank experiments, we tested capture rate plastics varying size, shape, polymer type, as well chemical residues leached by degraded plastics, all which accumulated filter. Expanded polystyrene foam was most readily captured type plastic, followed fragments, fibers, nurdles, spherical microbeads. Nurdle microbead pellets were right fragments humpback baleen. Although differences between types statistically significant, buoyant polymers often trapped Plastics sections regions a full rack, but more dorsal posterior regions. Baleen–plastic interactions underlie various risks to including filter clogging damage, may impede We posit pose higher risk some due combination factors, porosity, diet, habitat geographic distribution, foraging ecology behavior.
