13. Multiple responses of gram-positive and gram-negative bacteria to mixture of hydrocarbons
Most of our knowledge about pollutants and the way they are biodegraded in the environment has previously been shaped by laboratory studies using hydrocarbon-degrading bacterial strains isolated from polluted sites. In present study Gram-positive (Mycobacterium sp. IBB Po1, Oerskovia sp. IBB Po2, Corynebacterium sp. IBB Po3) and Gram-negative (Chryseomonas s

14. Toxic effects of cadmium on the microalgae Lingulodinium polyedrum using high performance liquid chromatography coupled to mass spectrometry (LC-MS/MS) / Análise dos efeitos tóxicos de cádmio sobre a microalga Lingulodinium polyedrum utilizando cromatografia líquida de alta eficiência acoplada à espectrometria de massas (LC-MS/MS)
Given the increase of environmentally harmful human activities, in particular the ones injurious to the aquatic environment, it is important to elucidate the defense mechanisms utilized by organisms exposed to damaging agents. Those species can later be suggested to be used as pollution bioindicators or bioremediatiors. Algae are of particular importance bec

15. O ÍNDICE DE SUSTENTABILIDADE AMBIENTAL DO USO DA ÁGUA (ISA) COMO FERRAMENTA DE CONTRIBUIÇÃO ÀS POLITICAS PÚBLICAS DE DESENVOLVIMENTO E CONSERVAÇÃO NA BACIA DO RIO BACANGA, SÃO LUÍS/ MA. / INDEX FOR ENVIRONMENTAL SUSTAINABILITY OF WATER USE (ISA) AS A TOOL FOR CONTRIBUTION TO THE POLICIES PUBLIC DEVELOPMENT AND CONSERVATION IN BACANGA RIVER BASIN, SÃO LUIS / MA.
A hydrographic basin is a complex environmental system, resulting from the interrelations between the physical-natural and socioeconomic subsystems. Its identity as the unifying of environmental processes and human interference is leading to its adoption as a research unit. It allows from the analysis of the physical-chemical, biological and socioeconomic fa

16. A theoretical essay on sustainability and environmentally balanced output growth: natural capital, constrained depletion of resources and pollution generation
The fact that today's activities are imposing a heavy burden on the earth's capacity has led to an increasing interest in environmental issues. It is emphasized that rapid production growth has exhausted natural resources and polluted the environment. The objective of this essay is to offer a clear definition of natural capital, connect it to a qualitative c

17. Problemática da poluição visual nas grandes metrópoles, Rua 25 de março: antecedentes e perpectivas. Análise histórica e iconográfica sob ótica da poluição e da complexidade das relações sócias, políticas e econômicas da sociedade pós-moderna / The visual pollution problematic in the big metropolis, March, 25th Street: antecedents and perspectives. History and iconography analysis under the visual pollution focus and the complexity of the post modern society social, political and economic relations
A relação existente entre os habitantes e a cidade em que vivem está intimamente ligada à forma de utilização do espaço urbano. Atualmente, nas grandes metrópoles, estamos assistindo uma situação bastante preocupante, onde esta utilização do espaço urbano vendo sendo traduzida em poluição visual. Neste contexto, a problemática da poluição v

18. Levantamento ambiental e pesqueiro dos rios Jaboatão e Pirapama no Estado de Pernambuco, Brasil
The increasing human populations that live on, work with and use resources of coastal areas place pressure on these resources, which, together with pressure from natural sources, must be monitored and understood in order to ensure the preservation of the environment and maintenance of quality of life. The rivers that empty along the coast of the state of Per

19. Estrutura e produtividade da comunidade fitoplanctÃnica de um estuÃrio tropical (SirinhaÃm, Pernambuco, Brasil)
The estuary of SirinhaÃm river located in the district of SirinhaÃm, Southern of Pernambuco state, (8Â34â-8Â37âS e 35Â04â-35Â01âW), was evaluating aiming to catalog the phytoplankton community, estimating its productive capacity, the temporal spatial dynamics and the principal environmental variables that affect its composition. The samplings of th

20. Uptake of Hg2+ from aqueous solutions by microporous titano- and zircono-silicates
Being mercury one of the most toxic heavy metals present in the environment, it is of major concern to develop cleanup technologies to remove it from wastewater and recover mercury polluted ecosystems. In this context, we study the potential of some microporous titanosilicates and zirconosilicates for taking up Hg2+ from aqueous solutions. These materials ha

21. Integrated environmental assesment of Santos estuarine system s disposal site and adjancent zones / Diagnostico ambiental integrado da area de influencia do descarte do material dragado do estuario de Santos
The Atlantic Forest coastal plain which surrounds the city of Santos in the State of São Paulo, Brazil, has a great economic importance, principally due to the port of Santos, the largest in Latin America, and the Cubatão industrial complex. The regions estuary has been polluted by multiple contaminant sources for decades, due to industrial, portuary and

22. Controle genético de mosquitos Culex quinquefasciatus / Genetic control of Culex quinquefasciatus mosquitoes
The Culex quinquefasciatus mosquitoes are considered urban plague and are able to grown in polluted water achieving high density. This specie are important vectors in the transmission of parasites and arbovirus. Chemical control methods shown to be ineffective and highly hazards to the environment. In this way, new technologies of control have been developed

23. Hydrological potential of the Monte Olimpo watershed on Campus Luiz de Queiroz of the University of São Paulo / Potencialidades hídricas da microbacia hidrográfica do córrego do Monte Olimpo no campus "Luiz de Queiroz" da Universidade de São Paulo
The goal of this work was to study the hydrological potential of the Monte Olimpo Watershed on Campus Luiz de Queiroz of the University of São Paulo. This watershed is located entirely on the Campus, where good water quality can be stored in two reservoirs. Due to the lack of soil conservation practices and environment concerns this watershed is much degrad

24. Metaproteomic and biochemistry hydrocarbons and heavy metals-contaminated soils / Metaproteomica e bioquimica de solos contaminados por hidrocarbonetos e metais pesados
Hydrocarbons, heavy metals and agricultural defensives are high risk pollutants to human health. These pollutants are constantly introduced into the environment as a result of petrochemical, industrial, agricultural activities and our modern life style, requiring remediation processes that are used to their complete elimination. Bioremediation is a process c
