1. Adaptive and cross-protective responses against cadmium and zinc toxicity in cadmium-resistant bacterium isolated from a zinc mine
Cadmium (Cd) is a major environmental hazard, which usually is detected in its ionic form of Cd2+. It also causes adverse toxic effects on human health and other living organisms. Cd-resistant bacteria were isolated from Cd-contaminated soils. One isolate, TAK1, was highly resistance level to Cd toxicity. TAK1 was isolated from soil contaminated with a high

2. Condutividade eletrosmótica e remediação de solos contaminados com cádmio via eletrosmose / Electroosmotic conductivity and remediation of cadmium contaminated soils via electroosmosis
O presente trabalho abordou a aplicação de fenômenos eletrocinéticos na remediação de solos, com um direcionamento ao emprego da eletrosmose na descontaminação de três solos da Zona da Mata Norte, estado de Minas Gerais, Brasil, contaminados com o elemento- traço cádmio. Buscou-se ampliar o horizonte de pesquisas já desenvolvidas na Universidade

3. Aplicação de resíduo URA na remediação química de solos contaminados por Cd, Pb e Zn. / Application of residue URA in the chemical remediation of soil contaminated by Cd, Pb and Zn.
The objective of this study was to evaluate the alteration in the solubility of heavy metals in soils contaminated by anthropic action, applying an iron oxide residue (CSN) that acted from the chemical containment, aiming to recover contaminated areas and representing a low cost alternative in the containment of heavy metals. An experiment was conducted in t

4. Remediation of cadmium- and lead-contaminated soils with an aluminum industry by-product / Subproduto da indÃstria de alumÃnio na remediaÃÃo de Ãreas contaminadas com cÃdmio e chumbo
Mining activities have been increasing each day and generate large amounts of residues or by-products, which have caused a lot of interest by researchers in evaluating their potential use as soil amendments. One of the applications of such amendments is on the remediation of soils contaminated with trace elements, which might pose a threat to animals and pla

5. Tratabilidade de solos tropicais contaminados por resíduos da indústria de revestimentos cerâmicos. / Treatability of tropical soils contaminated by solid wastes from ceramics covergin industry.
The Ceramic Pole of Santa Gertrudes, located in the region of Rio Claro, in the State of São Paulo, is the largest of the gender in the country, counting with more than 40 industrial units of the section of floors and coverings and responsible for more of the half of the national production. The area of studies, denominated Region of the Lakes of Santa Gert

6. Tratamento in-situde solo contaminado por derivado de petróleo e metais. / In-situ treatment of soil contaminated by oil derivative and metals.
A contaminação de solos por derivados de petróleo é freqüente no Estado de São Paulo. Nesta tese estudaram-se dois métodos de remediação de solo contaminado por derivados de petróleo: a oxidação química e a biorremediação, em condições in-situ. Usou-se o benzeno como hidrocarboneto modelo em ensaios em laboratório. Nos tratamentos oxidativo

7. Effect of Toxic Metals on Indigenous Soil β-Subgroup Proteobacterium Ammonia Oxidizer Community Structure and Protection against Toxicity by Inoculated Metal-Resistant Bacteria
Contamination of soils with toxic metals is a major problem on military, industrial, and mining sites worldwide. Of particular interest to the field of bioremediation is the selection of biological markers for the end point of remediation. In this microcosm study, we focus on the effect of addition of a mixture of toxic metals (cadmium, cobalt, cesium, and s
