Trace metals concentrations in mangrove sediments of Sepetiba Bay (Rio de Janeiro, Brazil): microwave assisted digestion with nitric acid and aqua regia. Mangrove sediments have a great capacity to accumulate trace metals that can be remobilized thus contaminating the water and biota. Concentrations of trace metals (Cu, Ni, Pb and Zn) in mangrove sedim... ... Repository: BDPA Publication year: 2012
Trace metals in the urban aerosols of Rio de Janeiro city. From January to April 2009, samples of suspended particles (TSP) and particulate matters (PM10 and PM2.5) were collected from a well-characterized urban area that is highly impacted by vehicular traff... ...

Concentration of airbone trace metals in a bus station with a high heavy-duty diesel fraction. Total particulate matter (TSP) and PM10 samples were collected in a bus station, in the period of August 2006 to February 2007. Buses are the only significant emission sources in this area once light... ... Repository: BDPA Publication year: 2009
Ecotoxicity of mercury to Folsomia candida and Proisotoma minuta (Collembola: isotomidae) in tropical soil: baseline for ecological risk assessment. Mercury (Hg) is a highly toxic nonessential trace metal. Despite its natural occurrence in the Earth's Crust, its concentrations have been steadily increasing in the environment due to anthropogenic s... ... Repository: BDPA Publication year: 2016
Seasonal study of concentration of heavy metals in waters from lower São Francisco River basin, Brazil. In this study we determined the concentration of metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in the water lower São Francisco River basin, to evaluate the influence of urbanization and industrializatio... ...

Efecto de la aplicación del lodo del tratamiento de aguas negras en Argisuelo Rojo-Amarillo cultivado con plátano (Musa spp). The need for solutions that minimize negative environmental impacts, generated by anthropogenic activities, has been increasing. Sewage sludge (SS) has predominantly organic composition and can improv... ... Repository: BDPA Publication year: 2006
Organic acids and biosolid trace elements phytoavailability. Trace metals phytoavailability is a major concern related to land application of biosolids. Formation of soluble complexes between metals and organic acids exudates in the rhizosphere b plants or prod... ... Repository: BDPA Publication year: 2005
Plant growth, nutrients and potentially toxic elements in leaves of yerba mate clones in response to phosphorus in acid soils. Native to subtropical region of South America, yerba mate is responsive to P under some conditions, but the degree of influence of genetic and soil on the growth and composition of the leaf is unknown... ...

Heterogeneity in the chemical composition of biofertilizers, potential agronomic use, and heavy metal contents of different agro-industrial wastes. The objective of the present study was to evaluate the chemical characteristics of agro-industrial residues used in the manufacture of an aerobic liquid biofertilizer. We analyzed the macronutrient, m... ... Repository: BDPA Publication year: 2019
Soil-atmosphere exchange of nitrous oxide, nitric oxide, methane, and carbon dioxide in logged and undisturbed forest in the Tapajos National Forest, Brazil. Selective logging is an extensive land use in the Brazilian Amazon region. The soil?atmosphere fluxes of nitrous oxide (N2O), nitric oxide (NO), methane (CH4), and carbon dioxide (CO2) are studied on... ... Repository: BDPA Publication year: 2005
