13. Application of the fundamental parameter method to the assessment of major and trace elements in soil and sediments from Osamu Utsumi uranium mine by WDXRF
Abstract Wavelength dispersive X-ray fluorescence spectrometry (WDXRF) is a suitable technique for the characterization of contaminated mining sites, providing a quick and reliable screening for areas of significant contamination. This study established and validated a non-destructive methodology for quantitative simultaneous determination of major and minor

15. Leaching of Herbicides Commonly Applied to Sugarcane in Five Agricultural Soils
RESUMO: A intensidade da lixiviação depende das propriedades físico-químicas dos solos e dos herbicidas. Consequentemente, uma boa compreensão desse processo é essencial para a determinação de medidas de mitigação para reduzir ou eliminar o risco de contaminação de águas próximas às áreas cultivadas com cana-de-açúcar. Portanto, o objetivo

16. Assessment of Trace Element Contents in Soils and Water from Cerrado Wetlands, Triângulo Mineiro Region
ABSTRACT In the Brazilian Cerrado biome, there are wetlands locally known as “Veredas”, which are swampy plains between hills and rivers. Since the 1970’s, the Cerrado biome has been gradually converted to livestock, crop, or forestry production. Until now, very few studies were conducted to evaluate the baseline contents of trace elements in Cerrado w

17. Estimation of Sulfentrazone Leaching in Isolated Application and in Mixture with Glyphosate
RESUMO: Como alternativa de controle de biótipos resistentes, os agricultores têm recorrido ao uso de herbicidas que possuem atividade residual no solo e têm boa ação em pré-emergência. Uma das misturas mais utilizadas no Brasil é a de sulfentrazone + glyphosate. Quanto um herbicida tem ação em pré-emergência, pequena lixiviação de suas molécu

18. Leaching of Imidazolinones in Irrigation Systems in Rice Cultivation: Sprinkling and Flooding
RESUMO: Herbicidas do grupo das imidazolinonas têm sido utilizados em arroz irrigado e apresentado longa persistência no solo, principalmente em áreas de várzea, com baixa drenagem, podendo ocasionar contaminação ambiental. Objetivou-se, com este trabalho, avaliar a lixiviação e o residual dos herbicidas pertencentes ao grupo das imidazolinonas em si

19. Liming on picloram leaching in dystrophic Red Yellow Latosol
RESUMO A prática da calagem pode influenciar a lixiviação de herbicidas nos solos, especialmente os com caráter ácido fraco, como é o caso do picloram. O estudo da lixiviação mantendo-se a estrutura do solo é um fator importante quando se busca compreender a dinâmica de herbicidas e possíveis impactos ambientais. Assim, objetivou-se avaliar o efei

20. Improvement of saline soils with Vicia sativa L. from a semiarid region
ABSTRACT In the Cienega de Chapala region of the state of Michoacan, Mexico, forage crops form a major pillar for traditional livestock systems. In this region, high soil salinity due to poor groundwater quality is a common problem. Thus, the objective of this research was to evaluate the potential of the forage species Vicia sativa L. for improved saline so

21. Effects of the silica nanoparticles (NPSiO2) on the stabilization and transport of hazardous nanoparticle suspensions into landfill soil columns
Abstract This study evaluates the stability and transport behaviors of hazardous nanoparticles into soil landfills using experimental procedures to simulate the effects of natural silica nanoparticle suspensions during their percolation into the soil layers of municipal waste landfills. For this, we prepared stabilized suspensions of nanoparticle oxides cont

22. PERFORMANCE OF TIFTON 85 GRASS UNDER FERTIRRIGATION WITH SLAUGHTERHOUSE WASTEWATER
ABSTRACT: The aim of this study was to evaluate the performance of Tifton 85 grass cultivated in soil columns and fertilized with different wastewater doses of swine slaughterhouse. The experiment was conducted in the Environmental Engineering Center and Sanitary of UFLA/MG in PVC columns filled with Dark Red Latosol (Oxisol) and randomly distributed. The tr

23. Reducing the leachability of nitrate, phosphorus and heavy metals from soil using waste material
Abstract Contaminants like nitrate (NO3), phosphorus (P) and heavy metals in water are often associated with agricultural activities. Various soil and water remediation techniques have been employed to reduce the risk associated with these contaminants. A study was conducted to examine the extent of leaching of heavy metals (Cd, Ni, Pb and Cr), NO3 and P. Fo

24. Nutrient Release, Plant Nutrition, and Potassium Leaching from Polymer-Coated Fertilizer
ABSTRACT The increase in food consumption and limitations in food production areas requires improved fertilizer efficiency. Slow- or controlled-release fertilizers are an alternative for synchronizing nutrient availability with the plant demands, reducing losses to the environment. The aim of this study was to evaluate the efficacy of polymer-coated KCl comp
