1. Mapping of areas suitable for the application of biosolids in the Quadrilátero Ferrífero region, Minas Gerais, Brazil
Abstract The recovery of degraded areas is imperative for the sustainability of mining activities. The main action implemented to improve the chemical, physical and biological conditions of soils, tailings and sterile deposits is the incorporation of organic material. Biosolids (hygienized sewage sludge) are among the organic materials that can be applied. H

2. Validation of a Standard Operating Procedure (SOP) for Forensic Soils Investigation in Brazil
ABSTRACT Soil traces are useful as forensic evidence due to their potential to transfer and adhere to different types of surfaces on a range of objects or persons. Several works have been developed in forensic soils, under different analytical approaches. However, in Brazil, only the researches from the Group of the Federal University of Paraná have develop

4. Analysis of the effect of impermeability of urban soils on the infiltration of rainwater in the city of Recife, PE
Resumo O processo de urbanização interfere nos elementos do ciclo hidrológico, alterando as características de infiltração, escoamento e evaporação da água oriunda da chuva. Para analisar este ciclo hidrológico há diversos métodos e ensaios que visam caracterizar hidrodinamicamente o solo de uma localidade. Entretanto, a realização de coletas e

5. Field Description and Identification of Diagnostic Qualifiers for Urban Soils in Brazil
ABSTRACT Human activities often alter soils found in urban areas. These alterations affect their environmental functions and potential for use. However, soils from urban areas in Brazil have not been surveyed and identified, which can pose a technical problem for the development of the city. Considering the importance of urban environments and their soils, t

6. PCDD/Fs and PCBs in Soils: a Study of Case in the City of Belo Horizonte-MG
Dioxins (polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs)) are substances that represent a global concern due to their ubiquitous presence and toxicity. Industrial processes and other human activities as well as uncontrollable accidents are the main sources that release these pollutants into t

7. GIS-based analysis of geo-resources and geo-hazards for urban areas - the example of the northern periphery of Belo Horizonte (capital of Minas Gerais, Brazil)
Abstract Easily understandable thematic maps of geo-scientific parameters are important for land use decision making. If several parameters are relevant and have to be compared, it is important that they are consistent with each other, available at the same spatial range and detail and normed to a common data range. In the current study, geological and topog

8. Estimates of Annual Soil Loss Rates in the State of São Paulo, Brazil
ABSTRACT: Soil is a natural resource that has been affected by human pressures beyond its renewal capacity. For this reason, large agricultural areas that were productive have been abandoned due to soil degradation, mainly caused by the erosion process. The objective of this study was to apply the Universal Soil Loss Equation to generate more recent estimate

9. Chumbo e cádmio detectados em alimentos vegetais e gramíneas no município de Santo Amaro-Bahia
This study evaluated the level of the metals Pb mg kg-1 and Cd mg kg-1 found in plant species and the contribution of the levels detected in contaminated soils located in the urban area of the city of Santo Amaro, Bahia. Levels were determined by graphite furnace and flame atomic absorption spectrometry. The results showed the presence of Pb and Cd in plant

10. Fitoextração em solo contaminado com metais pesados / Phytoextraction of soil contaminated with heavy metals
The industrial and urban progress associated with increased production of consumer goods has resulted in the generation of waste, which, for a long time, was indiscriminately discarded in the environment, causing damage usually irreversible to recover. Two experiments were conducted in soils contaminated with heavy metals: the first aimed at the disposal of

11. Uso de materais não convencionais para base de pavimentos asfálticos no muunicípio de Aparecida de Goiânia - GO / The use of non-conventional materials for asphalt pavements base in the city of Aparecida de Goiânia-GO
The city of Aparecida de Goiania-GO has a current estimate of 16,782,313 m of urban roads, and there are still 51.5% to be paved. However, the technical staff of the mayor is facing a challenge related to the purchase of lateritic gravel for paving of these streets. Taking into account that most roads in the city has a low volume of traffic (N ≤ 5.105)

12. Pedoforms mapping at the Águas Emendadas ecological station, Distrito Federal, Brazil.
The great urban and rural development of the Distrito Federal (Federal Administrative District) in Brazil over the last 50 years has led to disordered land use and land occupation. To assess the current environmental scenario, detailed surveys of the available natural resources, especially soils, are required. The objective of this work was to evaluate the s
