1. Qualidade da água potável consumida na Cidade do Salvador - Bahia
The research talks about the drinking water which is consumed in Salvador city and presents the main health consequences of the contaminants that can be found in the water and the prevention measurements more suitable to remove them. Contaminations which can be found in the water sources come from the growth industrial activities, synthetic agriculture compo

2. Critical rains, planning and run-off management using geografic information system on Presidente Bernardes - Cubatão Refinery (RPBC) / Precipitações criticas, planejamento e gerenciamento das drenagens superficiais utilizando sistemas de informações geograficas : Refinaria Presidente Bernardes - Cubatão (RPBC)
The increase on the rains intensity veryfied on last decades has requested the conveyances over than their capacity, showing deficiencies on old designed systems. At the same time, society has the crying need of water resources conservation, justified by the water s scarcity. In an oil refinery this subject is particularly important because of the great amou

3. Agrarian soil and sediment redistribution and quality in slopes with riparian forests: a case study for Goiatuba, Brazil / Redistribuição e qualidade de solos e sedimentos agrícolas em vertentes com mata ciliar: estudo de caso em Goiatuba (GO), Brasil
Soil erosion is associated with environmental degradation because of inadequate use of natural resources in modern agriculture, thus promoting in and off-site impacts, represented by soil, water and nutrient losses, silting and contamination of riparian ecosystems. In the Brazilian Cerrado region these impacts become more evident by its fast conversion to ag

4. Potencial de poluição de aguas superficiais por fontes não pontuais de fosforo na Bacia hidrografica do Ribeirão do Pinhal, Limeira- SP
Em áreas rurais onde há intensa atividade agrícola, a eutrofização de corpos de água pode ser acelerada pelo influxo de nutrientes, provenientes de fertilizantes, transportados por escoamento superficial. A eutrofização pode provocar mudanças indesejáveis na estrutura e funções do ecossistema, bem como na qualidade da água destinada ao abastecim

5. CaracterizaÃÃo e aproveitamento da Ãgua de coco seco (Cocus nucifera L.) na produÃÃo de bebidas
Ripen coconut water considered as industrial runoff was used in addition to passion fruit pulp as ingredient to formulate nectar and an isotonic drink. The physical-chemical composition of ripen coconut water was determinate and the formulations of both products were defined by sensory tests. Both products were conditioned in glass bottles and pasteurized in

6. Estudo da Interação entre Atividade Bacteriana, Metais Pesados e Matéria Orgânica nos Sedimentos da Baía de Guanabara - RJ / Estudo da Interação entre Atividade Bacteriana, Metais Pesados e Matéria Orgânica nos Sedimentos da Baía de Guanabara - RJ / Estudo da Interação entre Atividade Bacteriana, Metais Pesados e Matéria Orgânica nos Sedimentos da Baía de Guanabara - RJ
The Guanabara bay represents a coastal environment propitious to the studies of environmental quality, for presenting an exuberant nature, with innumerable ecosystems in contraposition with one of the highest urban and industrial concentrations of the country. The toxicity of metals is determined not only by its concentration, but by the chemical form it pre

7. Degradação de hidrocarbonetos aromaticos policiclicos por bacterias
Polycyclic aromatic hydrocarbons (PAHs), constitute a class of hazardous organic chemicals consisting of three or more fused benzene rings. PAHs mostley occur as a result of fossil fuel combustion, as by-products of industrial processing, and during the cooking of foods. PAHs enter the environment from a multiplicity of sources which include: accidental disc

8. Nitrification in the intertidal zone: influence of effluent type and effect of tannin on nitrifiers.
Nitrification by intertidal sediments was measured by using a tide simulator that approximated the cycle of seawater on tidal flats. Sediments were chosen from sites affected by industrial and municipal effluents and pastoral seepage and runoff. The ability of sediments from different sites to nitrify endogenous nitrogen varied markedly. All sites exhibited
