1. Superfosfato triplo, lama vermelha e zeólitas para remediação de metais pesados em solo contaminado / Remediation of contaminated soil with heavy metal using triple superphosphate, red mud and zeolites
Due to the heavy metal persistence in soils, the contamination by these elements is considered permanent and might result in great impact causing a degradation of the chemical and biological properties of the soil. Stabilization techniques have been used as an efficient tool for the remediation of soils that are contaminated by heavy metals, and they show al

2. Uso de resíduo orgânico da produção de biodiesel direta da semente na atenuação dos efeitos de hidrocarbonetos de petróleo no solo. / Use of organic residue from the biodiesel production directly from the seed in the reduction of petroleum hydrocarbons effect in soil.
In the search for energy resources that can minimize the environmental impact in the transportation, refining and distribution of fossil fuels, biodiesel is highlighted as an economically viable alternative and totally renewable if compared to petroleum. With the regulations of Law 11097, from 2005, Brazil became widely known as one of the planet largest pro

3. SIMULATION OF ATRAZINE DEGRADATION BY IN SITU ELECTROCHEMICALLY GENERATED OZONE FOR GROUNDWATER REMEDIATION / SIMULAÇÃO DA DEGRADAÇÃO DE ATRAZINA COM OZÔNIO GERADO ELETROQUIMICAMENTE IN SITU PARA REMEDIAÇÃO DE ÁGUAS SUBTERRÂNEAS
The impact of pesticides on the quality of groundwater has been the subject of scientific and public health concerns in the entire planet, especially in areas where groundwater is mainly used for human consumption. The intensive use of pesticides in agriculture and the high persistence of several of these chemicals have required a rigorous control of possibl

4. Degradação de naftaleno, fenantreno e benzo(a)pireno em solos e sedimentos de ambientes costeiros, oceânicos e antárticos / Degradation of naphthalene, phenanthrene e benzo(a)pyrene in soil and sediments of coastal, oceanic and Antarctic environments
Petroleum is the main source of fuel, and the operations of exploration, transportation, refining and distribution are potential sources of environmental pollution. In contaminated environments, the degradation of PAHs (Polycyclic Aromatic Hydrocarbons) depends on climatic factors, soil and microbial population. This study aimed to assess the potential for d

5. Biossorção de cádmio por linhagens de Aspergillus sp / Biosorption of cadmium by Aspergillus sp. strains
The heavy metals represent the major industrial residues contaminant of soils, plants and animals in the ecosystems, causing a toxic effect to humans, mainly due to the wide spread distribution in environment which is intensified by industrialization process. One of most toxics heavy metals is cadmium, commonly used in industrial process, what make it an imp
