Microplastics (MP) pollution has received increased attention over the last few years. However, while number of studies documentating ingestion microplastics by fish increased, fewer have addressed toxicological effects derived from these small items in wild conditions. Here, MP contamination and effect biomarkers were investigated three commercially important species North East Atlantic Ocean. From 150 analysed (50 per species), 49 % had MP. In 3 species, gastrointestinal tract, gills...
Abstract Planktivorous pelagic fish are susceptible to accumulating microplastics (MP), which have the same size range as their prey and accumulate in feeding spawning grounds. We analyzed stomach contents of (European sardine, horse mackerel, anchovy, chub Atlantic bogue) from Atlanto‐Iberian waters investigate relationship between MP ingestion, diet composition select a potential bioindicator. found significant differences studied species terms type size. ingestion was significantly...
Wild fish (Cyprinus carpio, Mugil cephalus, Platichthys flesus) from an estuary of the NE Atlantic coast were investigated for plastic contamination (N = 128). From 1289 particles recovered samples, 883 plastics. Among these, 84% fibres and 97% microplastics. Thirty-six polymers identified. The number microplastics (mean ± SD) per individual (MP/fish) was 8 6 in C. 10 9 M. cephalus 2 P. flesus. means MP/fish body site 7 gastrointestinal tract, 0.5 1.1 gills, 0.3 0.7 liver 0.6 1.2 muscle...
Increased Rare earth elements (REE) usage culminates in discharges into the environment. Mussels have been chosen as models biomonitoring, hence, REE concentrations Mytilus galloprovincialis from six locations on Portuguese coast were accessed to determine natural and possible linkage local ecosystem characteristics temporal variations, by determining them distinct seasons (autumn spring). Samples Porto Brandão (located south bank of Tagus estuary) exhibited highest concentrations, while...
The accumulation of microplastics (MP) by marine species ecological and commercial interest represents a major concern, particularly for those present in human diet. This study analysed the MP three coastal pelagic fish with high value, European sardine (Sardina pilchardus), anchovy (Engraulis encrasicolus) horse mackerel (Trachurus trachurus), collected along Western coast Iberian Peninsula. gastrointestinal tract (GT), gills muscle were total 504 particles observed. found all target...
Potassium hydroxide (KOH) digestion protocols are currently applied to separate microplastics from biological samples, allowing efficient with minor degradation of polymers in a time- and cost-effective way. For biota samples high-fat content, KOH reacts triglycerides generating an overlying soap layer, making difficult the solubilization subsequent extraction. Here we studied addition Tween-20 different concentrations evaluate effect on layer post-digested samples. Addition 10 % presented...
Humans have exhaustively combusted fossil fuels, and released pollutants into the environment, at continuously faster rates resulting in global average temperature increase seawater pH decrease. Climate change is forecasted to exacerbate effects of such as emergent rare earth elements. Therefore, objective this study was assess combined rising (Δ = + 4 °C) decreasing - 0.4 units) on bioaccumulation elimination gadolinium (Gd) bioindicator bivalve species Spisula solida (Surf clam). We...
Studies dealing with Rare Earth Elements (REE) ecotoxicological behavior are scattered and potential conflicting results. Climate change impacts on aquatic biota is known to modify contaminants toxicokinetic. Nevertheless, the current knowledge interactions between climate REE virtually non-existent. Therefore, we focus our research La Gd as representatives of Light Heavy that also great environmental concern. Experiments different mediums (fresh-, brackish- seawater) were designed run at...
Anthropogenic increased atmospheric CO2 concentrations will lead to a drop of 0.4 units seawater pH and ocean warming up 4.8°C by 2100. Contaminant's toxicity is known increase under climate change scenario. Rare earth elements (REE) are emerging contaminants, that until now have no regulation regarding maximum concentration discharge into the environment become vital new technologies such as electric hybrid-electric vehicle batteries, wind turbine generators low-energy lighting. Studies...
Mola mola is the largest teleost inhabiting our ocean and presence of microplastics (MP) in this flagship species was, before study, never described. Thus, investigation focused on analysing MP ingestion 53 giant sunfish Northeast Atlantic Ocean. A total 116 were found 79% specimens, with a median 1 MP.ind−1, ranging from 0 to 11 MP.ind−1. Seasonal differences observed, more fibers registered specimens caught autumn. Among different size classes smallest category (<300 μm) was most frequent...
