Nanoplastic debris, resulted from runoff and weathering breakdown of macro- microplastics, represents an emerging concern for marine ecosystems. The aim the present study was to investigate disposition toxicity polystyrene nanoparticles (NPs) in early development sea urchin embryos (Paracentrotus lividus). NPs with two different surface charges where chosen, carboxylated (PS-COOH) amine (PS-NH2) polystyrene, latter being a less common variant, known induce cell death several vitro systems....
Several studies have documented that plastic pollution is affecting one of the most remote and pristine regions our planet, Antarctica. Plastics different size polymeric composition been retrieved in Antarctic sea ice, surface waters sediments, with microplastics (mostly fibers) found both terrestrial marine organisms. Such evidence raises concerns about potential detrimental effects on biodiversity ecosystem functions. The present review aims to report up-to-date knowledge occurrence...
Polystyrene nanoparticles have been shown to pose serious risk marine organisms including sea urchin embryos based on their surface properties and consequently behaviour in natural water. The aim of this study is investigate the toxicity pathways amino polystyrene (PS-NH2, 50 nm) Paracentrotus lividus terms development signalling at both protein gene levels. Two sub-lethal concentrations 3 4 μg/mL PS-NH2 were used expose water (PS-NH2 as aggregates 143 ± 5 nm). At 24 48 h post-fertilisation...
Due to production, usage and disposal of nano-enabled products as well fragmentation bulk materials, anthropogenic nanoscale particles (NPs) can enter the natural environment through different compartments (air, soil water) end up into sea. With continuous increase production associated emissions discharges, they reach concentrations able exceed toxicity-thresholds for living species inhabiting marine coastal areas. Behavior fate NPs in waters are driven by transformation processes occurring...
There is evidence and serious concern that microplastics have reached the most remote regions of planet, but how far they travelled in terrestrial ecosystems? This study presents first field-based plastic ingestion by a common central component Antarctic food webs, collembolan Cryptopygus antarcticus . A large piece polystyrene (PS) foam (34 × 31 5 cm) covered microalgae, moss, lichens microfauna was found fellfield along shores Fildes Peninsula (King George Island). The application an...
Plastic debris has been identified as a potential threat to Antarctic marine ecosystems, however, the impact of nanoplastics (<1 μm) is currently unexplored. krill (Euphausia superba) keystone species Southern Ocean pelagic which plays central role in food webs and carbon (C) cycle. Krill shown rapidly fragment microplastic beads through digestive system, releasing with unknown toxicological effects. Here we exposed juveniles carboxylic (COOH, anionic) amino- (NH2, cationic) polystyrene...
The number of scientists and tourists visiting Antarctica is on the rise and, despite management framework for environmental protection, some coastal areas, particularly in Antarctic Peninsula region, are affected by plastic contamination. few data available occurrence microplastics (<5 mm) difficult to compare, due different methodologies used monitoring studies. However, indications emerging guide future research implement protocols. In surface subsurface waters Southern Ocean, debris...
Microplastics (MP) have been reported in Southern Ocean (SO), where they are likely to encounter Antarctic zooplankton and enter pelagic food webs. Here we assess the presence of MP within krill ( Euphausia superba ) salps Salpa thompsoni quantify their abundance type by micro-Fourier transform infrared microscopy. were found both species, with fibres being more abundant than fragments (krill: 56.25% salps: 22.32% total MP). Polymer identification indicated originated from local distant...
Invertebrates represent the most plentiful component of marine biodiversity. To date, only few species have been documented for litter intake. Here, we report first time presence macroplastic debris in a jellyfish species. Such novel target to plastic pollution highlights an under studied vector along trophic web, raising further concern over impact on wildlife.
In order to assess the impact of nanoplastics on marine species, polystyrene nanoparticles (PS NPs) have been largely used as model particles. Here we studied effects 50 nm amino-modified PS-NH2 Mediterranean sea urchin Paracentrotus lividus immune system cells (coelomocytes) in presence celomic fluid (CF) and at different NP concentrations (1, 5, 10, 25 μg mL−1) experimental conditions (absence or EDTA). acquired a protein corona once incubated with CF, dominated by toposome precursor...
