Plastic debris is widespread in the environment, but information on effects of microplastics terrestrial fauna completely lacking. Here, we studied survival and fitness earthworm Lumbricus terrestris (Oligochaeta, Lumbricidae) exposed to (Polyethylene, <150 μm) litter at concentrations 7, 28, 45, 60% dry weight, percentages that, after bioturbation, translate 0.2 1.2% bulk soil. Mortality 60 days was higher than 7% w/w control (0%). Growth rate significantly reduced microplastics, compared...
The amount of nano- and microplastic in the aquatic environment rises due to industrial production plastic degradation into smaller particles. Concerns have been raised about their incorporation food webs. Little is known fate effects nanoplastic, especially for freshwater environment. In this study, nano-polystyrene (nano-PS) on growth photosynthesis green alga Scenedesmus obliquus growth, mortality, neonate production, malformations zooplankter Daphnia magna were assessed. Nano-PS reduced...
It has been speculated that marine microplastics may cause negative effects on benthic organisms and increase bioaccumulation of persistent organic pollutants (POPs). Here, we provide the first controlled study plastic including transfer POPs. The polystyrene (PS) microplastic survival, activity, bodyweight, as well 19 polychlorinated biphenyls (PCBs), were assessed in bioassays with Arenicola marina (L.). PS was pre-equilibrated natively contaminated sediment. A positive relation observed...
Quantifying the transport of plastic debris from river to sea is crucial for assessing risks human health and environment. We present a global modelling approach analyse composition quantity point-source microplastic fluxes European rivers sea. The model accounts different types sources microplastics entering systems via point sources. combine information on these with sewage management retention during largest rivers. Sources include personal care products, laundry, household dust tyre road...
As the industrial production of nanoplastic and degradation microplastic into smaller particles at sea increase, potential amount nanoplastics in marine environment rises. It has been reported that mussels uptake 100-nm polystyrene (PS) beads; to date, however, effects this on organism are unknown. In present study, authors investigated 30-nm PS feeding behavior blue mussel (Mytilus edulis) by exposing different nano algae (Pavlova lutheri) concentrations. The state aggregation exposure...
It has been hypothesized that persistent organic pollutants (POPs) in microplastic may pose a risk to aquatic organisms. Here we develop and analyze conceptual model simulates the effects of plastic on bioaccumulation POPs. The accounts for dilution exposure concentration by sorption POPs (POP "dilution"), increased ingestion plastic-containing ("carrier"), decreased clean ("cleaning"). is parametrized lugworm Arenicola marina evaluated against recently published data this species from...
Diverse effects of nano- and microplastic (NMP) have been demonstrated in the laboratory. We provide a broad review current knowledge on occurrence, measurement, modeling approaches, fate, exposure, effects, effect thresholds as regard to microplastics aquatic environment. Using this information, we perform 'proof concept' risk assessment for NMP, accounting diversity material. New data is included showing how bioturbation affects exposure evaluated based literature model analyses. worst...
Researcher and media alarms have caused plastic debris to be perceived as a major threat humans animals. However, although the waste of in environment is clearly undesirable for aesthetic economic reasons, actual environmental risks different plastics their associated chemicals remain largely unknown. Here we show how systematic assessment adverse outcome pathways based on ecologically relevant metrics exposure effect can bring risk within reach. Results such an will help respond current...
It has been hypothesized that ingestion of microplastic increases exposure aquatic organisms to hydrophobic contaminants. To date, most laboratory studies investigated chemical transfer from ingested without taking other pathways into account. Therefore, we studied the effect polyethylene (PE) in sediment on PCB uptake by Arenicola marina as a model species, quantifying fluxes all natural pathways. concentrations sediment, biota lipids (Clip) and porewater measured with passive samplers were...
