The effect of nutrient enrichment on mangrove sediment accretion and carbon accumulation rates is poorly understood. Here we quantify through radionuclide tracers to determine organic (OC), total nitrogen (TN), phosphorus (TP) during the previous 60 years in both a nutrient-enriched pristine forest within same geomorphological region southeastern Brazil. receiving high loads has accumulated OC, TN, TP at that are fourfold, twofold, eightfold respectively, higher than those from undisturbed...
In the present research, occurrence of contamination by microplastics in water column was investigated 15 sample sites along rivers Guapimirim, Macacu and Maracanã—important that flow into Guanabara Bay, a very polluted estuarine environment Brazil. The correctidentified polymers were manually counted classified as to their morphology color using binocular stereomicroscope characterized ATR-FTIR spectroscopy. total mean abundance particles 3651.5 items m−3, ranging from 3.6 51,166.5 m−3....
O trauma é uma das principais causas de mortalidade em jovens, demandando manejo rápido e multidisciplinar para estabilização recuperação. Protocolos baseados evidências tecnologias imagem são fundamentais na avaliação intervenção. A colaboração entre especialidades médicas a personalização do tratamento contribuem melhores desfechos clínicos. reabilitação física o suporte psicológico essenciais reintegrar paciente ao cotidiano, minimizando sequelas físicas emocionais.

Acid drainage influence on the water and sediment quality was investigated in a coal mining area (southern Brazil). Mine showed pH between 3.2 4.6 elevated concentrations of sulfate, As metals, which, Fe, Mn Zn exceeded limits for emission effluents stated Brazilian legislation. Arsenic also limit, but only slightly. Groundwater monitoring wells from active mines tailings piles interval chemical similar to those mine drainage. However, river ground samples municipal public supplies revealed...
This paper reports on a study to determine the Hg content in five most abundant aquatic macrophyte species (Elodea densa, Sagittaria montevidensis, Salvinia auriculata, Pistia stratiotes and Eichhornia crassipes) two artificial reservoirs flooded by water diverted from Paraíba do Sul river, SE Brazil. The potential of these for accumulation their role transport along river system due management were evaluated. Mercury concentrations higher free-floating than rooted species. Roots also richer...
Precise and accurate δ 66/64 Zn data for environmental reference materials (RMs) including rocks, sediments, soils plants are presented in order to improve the metrological traceability analytical control of isotope ratio determinations future studies.Previously developed ion exchange chromatography protocols were adjusted enable faster sample throughput instrumental mass bias processes investigated.The improved chromatographic protocol yielded precise quantitative recoveries (99 ± 7%, σ, n...
