Uptake routes of microplastics in fishes: practical and theoretical approaches to test existing theories

Scientific Reports, Journal Year: 2020, Volume and Issue: 10(1)

Abstract Microplastics are frequently detected in the gastrointestinal tracts of aquatic organisms worldwide. A number active and passive pathways have been suggested for fish, including confusion microplastic particles with prey, accidental uptake while foraging transfer through food chain, but a holistic understanding influencing factors is still lacking. The aim study was to investigate theories identify relevant biotic factors, as well certain plastic properties, affecting intake fish. Four species freshwater each representing different combination style (visual/chemosensory) domestic status (wild/farmed) were exposed realistic concentrations polymer types without provision genuine food. As most previous investigations routes consider only large enough be perceptible potential via drinking water has somewhat neglected. This route evaluated current using model approach. results show that visually oriented fish forage actively on optically resemble their usual food, predominantly chemosensory more able discriminate inedible items.

Health impacts of environmental contamination of micro- and nanoplastics: a review

Environmental Health and Preventive Medicine, Journal Year: 2020, Volume and Issue: 25(1)

Published: July 14, 2020

Abstract Plastics are extensively used in our daily life. However, a significant amount of plastic waste is discharged to the environment directly or via improper reuse recycling. Degradation generates micro- nano-sized particles that defined as nanoplastics (MNPs). Microplastics (MPs) with diameter less than 5 mm, while (NPs) range from 1 100 1000 nm. In current review, we first briefly summarized environmental contamination MNPs and then discussed their health impacts based on existing MNP research. Our review indicates can be detected both marine terrestrial ecosystems worldwide ingested accumulated by animals along food chain. Evidence has suggested harmful freshwater animals. Recent studies found MPs human stool samples, suggesting humans exposed through and/or drinking water. effect scarcely researched. addition themselves, these tiny release additives adsorb other chemicals, many which have been shown exhibit endocrine disrupting toxic effects. summary, conclude more necessary provide comprehensive understanding pollution hazards also basis for subsequent management control.

Hazardous metal additives in plastics and their environmental impacts

Environment International, Journal Year: 2021, Volume and Issue: 156, P. 106622 - 106622

Published: May 21, 2021

Historically, many additives and catalysts used in plastics were based on compounds of toxic metals (and metalloids), like arsenic, cadmium, chromium(VI), lead. Despite subsequent restrictions, hazardous remain societal circulation because the pervasiveness products more general contamination recycled goods. However, little is understood about their presence impacts environment, with most studies focusing role acquiring from surroundings through, for example, adsorption. Accordingly, this paper provides a review uses hazardous, metal-based plastics, relevant European regulations that have been introduced to restrict or prohibit usage various sectors, likely environmental once are lost nature. Examination literature reveals widespread occurrence ranging waste stream increasing density settling rates material aquatic systems. A potential concern an ecotoxicological perspective diffusion matrix micro- nanoplastics under certain physico-chemical conditions, especially favorable here acidic environments encountered digestive tract animals (birds, fish, mammals) inadvertently consume plastics.

Sorption of PAHs to microplastic and their bioavailability and toxicity to marine copepods under co-exposure conditions

Environmental Pollution, Journal Year: 2019, Volume and Issue: 258, P. 113844 - 113844

Organic chemical pollutants associated with microplastic (MP) may represent an alternative exposure route for these chemicals to marine biota. However, the bioavailability of MP-sorbed organic under conditions where co-exposure occurs from same compounds dissolved in water phase has rarely been studied experimentally, especially pollutant concentrations two phases are well characterized. Importantly, higher on ingested MP be less bioavailable aquatic organisms than present form surrounding water. In current study, sorption kinetics model polycyclic aromatic hydrocarbons (PAHs; fluoranthene and phenanthrene) particles natural seawater at 10 20 °C were PAHs copepods investigated.
