The accumulation of plastic litter in natural environments is a global issue. Concerns over potential negative impacts on the economy, wildlife, and human health provide strong incentives for improving sustainable use plastics. Despite many voices raised issue, we lack consensus how to define categorize debris. This evident microplastics, where inconsistent size classes are used materials be included under debate. While this inherent an emerging research field, ambiguous terminology results...
The occurrence and effects of microplastics (MPs) in the aquatic environment are receiving increasing attention. In addition to their possible direct adverse on biota, potential role MPs as vectors for hydrophobic organic chemicals (HOCs), compared natural pathways, is a topic much debate. It evident, however, that temporal spatial variations MP do (and will) occur. To further improve estimations HOC transfer into biota under varying concentrations environmental conditions, it important...
Previous research reported the translocation of nano- and microplastics from gastrointestinal tract to tissues in Daphnia magna, most prominently fluorescent polystyrene beads lipid droplets. For particles >300 nm, such transfer is biologically implausible as peritrophic membrane retains these daphnid gut. We used confocal laser scanning microscopy study tissue applying setup a previous (neonates exposed 20 1000 nm at 2 µg L-1 for 4 24 h), same with fructose-based clearing, 1000-fold higher...
Planktonic copepods are the most abundant animals in ocean and key players global biochemical processes. Recent modeling suggests that zooplankton ingestion of microplastics (MPs) can disrupt biological carbon pump accelerate a loss oceanic oxygen. Here we investigate behavioral responses rates model feeding-current generating copepod when exposed to different characteristics by small-scale video observations bottle incubations. We found rejected 80% after touching them with their mouth...
Particles from tires are a major fraction of microplastic pollution. They contain wide range chemical additives that can leach into the water and be harmful to aquatic organisms. In this study, we investigated acute toxicity tire particle leachates in early life stages three keystone echinoderm species (Paracentrotus lividus, Arbacia lixula, Diadema africanum). Embryos were exposed for 72 h leachate dilutions, prepared using concentration 1 g L-1. Larval growth, abnormal development,...
We present a blue mussel exposure system where the fate of microplastics (polystyrene beads) is tracked during and depuration phases. This enabled establishment complete mass balance. Quantification beads in mussels was done with novel enzymatic digestion protocol. found similar relative distribution for 2 environmentally realistic concentrations (5 100 L-1 ) no substantial egestion particles within h depuration.

The entry of microplastics (MPs) into marine food webs is a major environmental concern. We investigated how the behavior planktonic copepods influences risk MPs to enter by applying trait-based approach and combining experiments (bottle incubations video observations) with biogeographical analyses. aimed evaluate which type feeding most risky in terms MP ingestion geographical areas are more susceptible copepods. used different species as models main foraging behaviors copepods:...
Shape matters for microplastics, but its definition, particularly hyperspectral imaged remains ambiguous and inexplicit, leading to incomparability across data. Hyperspectral imaging is a common approach quantification, yet no unambiguous microplastic shape classification exists. We conducted an expert-based survey proposed set of clear concise shapes (fiber, rod, ellipse, oval, sphere, quadrilateral, triangle, free-form, unidentifiable). The categories were validated on images 11,042...
The Arctic is undergoing rapid changes, and biota are exposed to multiple stressors, including pollution climate change. Still, little known about their joint impact. Here, we investigated the cumulative impact of crude oil, warming, freshening on copepod species Calanus glacialis finmarchicus. Adult females were ambient conditions (control; 0 °C + 33 psu) combined warming freshening: 5 27 psu (Scenario 1), 20 2) for 6 days. All three tested with without dispersed oil. In Scenario 1, fecal...

Abstract The use of trait-based approaches and trait data in zooplankton ecology is rapidly growing to better understand predict the patterns distributions their role aquatic ecosystems biogeochemical cycles. Although number studies available datasets increasing, several challenges remain for findability, accessibility, interoperability, reusability (FAIR) that, if unaddressed, may stifle progress this research area. Here, we review recent applications summarize currently resources. To...
Microplastics (MPs) and petroleum hydrocarbons are contaminants of emerging concern in the Arctic, but little is known about their co-exposure effects.In this study, we present first assessment sublethal impacts resulting from combined exposure to microplastics oil three key Arctic copepod species.Specifically, investigated effects a 5-day alone (1 μL L -1 ) combination with MPs (polyethylene microspheres, 20 μm, MP mL dispersant (Corexit 9500, 0.05 on biological functions lipid profiles...
