1. APLICAÇÃO DE NANOPARTÍCULAS DE FERRO ZERO-VALENTE (nFeZ) NA REMEDIAÇÃO DE SOLOS E ÁGUAS SUBTERRÂNEAS CONTAMINADAS: UMA REVISÃO
The remediation of contaminated soil and water is a relevant topic, being the focus of intense research. The use of nanoparticles to degrade contaminants has been consolidated as a sustainable remediation technology, with promising results worldwide. In this scenario, the zero-valent iron nanoparticles (nZVI) which, due to their properties, prove to be an im

2. Estimation of mercury released from an abandoned gold mine in Minas Gerais, Brazil
Abstract Mining is very important to the economic, political and social development of the Minas Gerais State in Brazil ever since the time the country became a Portuguese colony in the early 1500s. However, few researches have been conducted to evaluate the environmental impacts associated with the mining activity at this time. There are many abandoned mine

3. Evaluation of Phytoremediation Potential of Castor Cultivars for Heavy Metals from Soil
RESUMO: A fitorremediação é uma ferramenta útil para recuperar solos contaminados com metais pesados. Este estudo foi realizado para testar dois cultivares de mamona (Ricinus communis) [Local e DS-30] quanto à fitoextração de metais pesados de solo contaminado por concentrações conhecidas de sete metais (Cu, Cr, Fe, Mn, Ni, Pb e Zn). Um ensaio em va

4. Effect of Organic Matter on the Behavior and Control Effectiveness of Herbicides in Soil
RESUMO: Com o uso extensivo de herbicidas em áreas agrícolas, os riscos ambientais de contaminação de águas subterrâneas e superficiais por esses produtos têm se tornado preocupação mundial. Práticas de aplicação ou manutenção de resíduos orgânicos no solo que começaram a ser empregadas na agricultura para a nutrição dos solos têm demonst

5. Remediation of Soils Contaminated by Pesticides Using Physicochemical Processes: a Brief Review
RESUMO: Após anos de aplicação, muitas vezes de forma indiscriminada, de agrotóxicos, danos foram causados ao ambiente, bem como às culturas agronômicas cultivadas em locais contaminados. No tratamento de água são utilizadas técnicas que se baseiam em processos físicos e ou físico-químicos, onde ocorre a formação de agentes oxidantes secundári

6. Phytoremediation of Contaminated Soil with Sulfentrazone by Different Density of Crotalaria juncea
RESUMO: Em programas de fitorremediação de solo contaminado com herbicidas, faz-se necessário determinar a densidade adequada da espécie fitorremediadora, uma vez que essa prática irá contribuir para a eficiência do processo. Com isso, objetivou-se neste trabalho avaliar a influência da densidade de Crotalaria juncea sobre a fitorremediação de solo

7. Nitrogen and phosphorus uptake efficiency in Indian mustard cultivated during three growth cycles in a copper contaminated soil treated with biochar
RESUMO: O biocarvão tem sido usado mundialmente como um eficiente insumo agrícola devido à sua interação benéfica com as partículas e os nutrientes do solo. Contudo, seu efeito na disponibilidade de nutrientes como N e P em solos tropicais tem sido pouco investigado. O objetivo do estudo foi avaliar o efeito de diferentes tipos e doses de biocarvão

8. Synergy between cadmium and zinc in bean plants cultivated in multi contaminated soils
ABSTRACT. Agricultural species are subjected to a variety of biotic and abiotic stresses, which are the main limitations to crop production. In this context, contamination by trace elements is characterized as an abiotic stress that represents an environmental problem. Due to the physical and chemical similarities between cadmium and zinc, these elements may

9. Cupriavidus necator strains: zinc and cadmium tolerance and bioaccumulation
ABSTRACT: Among soil microorganisms, the genus Cupriavidus has garnered particular scientific, economic and ecological interest because of its ability to fix nitrogen and tolerate high concentrations of metals. The aim of this study was to analyze four strains of Cupriavidus necator for their ability to tolerate and bioaccumulate cadmium and zinc. The tolera

10. Rhizophagus Clarus and Phosphorus in Crotalaria juncea: Growth, Glomalin Content and Acid Phosphatase Activity in a Copper-Contaminated Soil
ABSTRACT Crotalaria juncea is used as plant cover in grape vineyards in Brazil, which usually present soils with high copper (Cu) levels due to the application of Cu-based phyto-sanitary products. Under this condition an increase growth and cover of C. juncea is needed to improve the phytoremediation processes in those soils. Some alternatives to achieve thi

11. Distribution and risk factors of Ascarididae and other geohelminths in the soil of Uberlandia, Minas Gerais, Brazil
ABSTRACT Among the geohelminths, parasites from the Ascarididae family have a significant role in the human and animal health. This research aims to determine the prevalence of Ascarididae species in the soil in different areas located in a city of Minas Gerais State, Brazil (South America). The study was developed in squares, parks, sports clubs, orchards a

12. Tolerance to and Accumulation of Cadmium, Copper, and Zinc by Cupriavidus necator
ABSTRACT Preliminary results of in vitro experiments with multicontaminated soils and solid media indicated that nodulating diazotrophic bacteria of the genus Cupriavidus are promising for the remediation of contaminated environments due to their symbiosis with legumes and metal tolerance. Thus, strains of Cupriavidus spp. (LMG 19424T, UFLA 01-659, UFLA 01-6
