1. Application of vermicomposting for the biorremediation of contaminated soil by polycyclic aromatic hidrocarbons / Aplicação de vermicompostagem para a biorremediação de solos contaminados por hidrocarbonetos policíclicos aromáticos
One of the main environmental problems that we face today is the soil contamination due to storage fuel tanks leakages. Fuels are comprised of a variety of hydrocarbons, among them are the polycyclic aromatic hydrocarbons (PAHs). Those are classified by US-EPA and NIOSH as prioritary contaminants, due to their carcinogenic and mutagenic characteristics and t

2. 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

3. Determination of organochlorine compounds and polycyclic aromatic hidrocarbons in Lagoa de Carapicuiba- SP / Determinação de compostos organoclorados e hidrocarbonetos poliaromáticos na Lagoa de Carapicuíba - SP
In 2002, started the workmanships of widening and deepening of the gutter of the river Tietê in the metropolitan area of Sao Paulo, as a tool to prevent the periodic floods that happen in this region. A large amount of sediment, rocks and garbage have been removed from the river and this same material has been deposited in the lagoa de Carapicuíba, which s

4. Study of structure-activity in polycyclic aromatic hidrocarbons / Estudo da atividade carcinogenica dos hidrocarbonetos policiclicos aromaticos atraves de descritores quanticos
Neste trabalho apresentamos estudos de estrutura-atividade realizados para 81 hidrocarbonetos policíclicos aromáticos (PAHs) tentando identificar compostos carcinogênicos. Em particular, empregamos uma nova metodologia desenvolvida para tratar o problema da correlação estrutura geométrica com atividade biológica, denominada Metodologia de Índices Ele
