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...
Abstract To improve our understanding and guide future studies applications, we review the biogeochemistry of rare earth elements (REE). The REEs, which form a chemically uniform group due to their nearly identical physicochemical properties, include lanthanide series plus scandium (Sc) yttrium (Y). These elements, in conjunction with neodymium isotopes, are powerful tools for key oceanic, terrestrial, biological even anthropogenic processes. Furthermore, unique properties render them...
The roots of the vascular plant Spartina maritima , growing in saltmarshes Tagus Estuary, Portugal, are surrounded by tubular concretions whose diameter can reach >0.2 cm. Concretions also found scattered within sediment matrix and below root zone. comprise 4% (DW) contain 11.7 ± 1.6% iron compared to 4.9 0.3% which they found. They formed precipitation oxides pores between grains; this has filled about one‐sixth originally available pore space. To produce concretions, plants have...
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...
Introduction: The catastrophic event that affected 2.3 million people and impacted almost all municipalities in the state of Rio Grande do Sul May 2024 is an example effects climate change on planet. Considering this period, study covered physical-chemical microbiological monitoring waters dos Sinos soils located flooded areas basin. Four water samples eleven soil were collected two campaigns. first occurred July second October 2024. For quality Sinos, results showed low concentrations...
