Avaliação do potencial genotóxico e mutagênico do efluente de uma refinaria de petróleo e dos rios sob sua influência, por meio de bioensaios com Oreochromis niloticus (Perciformes, Cichlidae)

The petrochemical industry represents a sector of intense activity, in constant expansion and great economic importance for Brazil. In order to be used in various human activities petroleum needs to suffer a refinement process that, besides requiring large amounts of water, produces large amounts of wastes, which are discharged in hydric resources. Petroleum is a complex mixture mainly comprised by hydrocarbons, many of them are recognized as toxic chemicals, which are able to induce a considerable environmental pollution. Since water is an important resource for the maintenance of ecosystems and is also the final receiver of effluent discharges of the petroleum industry, there is an imminent need to monitor, constantly, the hydric resources that are influenced by this industrial activity, so that it can be ensured the environmental health. This study aimed, mainly, to analyze the quality of water samples derived from refinement process performed of the largest petroleum refinery in Brazil (REPLAN), in distinct steps of the industry treatment, and waters of rivers associated to its activity. Micronuclei and Nuclear Abnormalities tests were performed in erythrocytes of the fish species Oreochromis niloticus exposed to water samples derived from refinery use and to rivers under the influence of their effluents, in order to evaluate its possible toxic, genotoxic and mutagenic effects. The results obtained show that the treatment carried out by the refinery, during the evaluated periods, was effective, since the substances present in the water samples did not induce significant genotoxic and/or mutagenic alterations in the genetic material of the test organisms. On the other hand, when the substances present in the refinery effluent mix with the ones derived from other industrial activities developed upstream of this industry, the resultant compound, in some periods, presented genotoxic potencial, characterized by a rise of erythrocytic...

Seeking the integrated management of water resources and financial compensation especially as a management tool, according to the Law No. 9433 of 1997 and No. 9985 of 2000. This research's main objective is measuring the flow contribution of Núcleo Santa Virginia, the State Park of Serra do Mar, starting from the hydrological regionalization method, developed by the Department of Water and Power. According to the Law 9985 of 2000 Conservation Units have the right to receive in the form of an investment a portion of the amount paid by Power Plants, being passed directly to the Conservation Units, differently from the 9433 Act. By dividing the area of Núcleo Santa Virgínia, in Sub-basins, it was possible to find the minimum flow during seven consecutive days, with a return period of ten years, Q7,10, and steady water flow in 95% of the time, Q95 for the Center and from these data to calculate the monetary value of law under Articles 47 and 48 from Law 9985 of 2000

Radiocronologia dos sedimentos do Lago de Constança

The dating of sediments in lakes, estuaries and rivers through radionuclides, when applied in association with other analitic methods (heavy metals, organic contaminants, etc.) allows analyses of the anthropogenic interference in the environment along the years. A geochronology of a sediment core from Untersee in Lake Constance, one of the most important hydric resources of Europe, was established through the Pb-210 method and adopting the CRS parameter (Constant Rate of Supply). The Cs-137 was successfully used to give basis to the results, as its additional input occurred in Chernobyl’s accident can be used as a marker to the year 1986. Associating the dating with the cores depth, the average mass accumulation rate and the sedimentation rate for the site were assessed (0,14 g/cm²/year and 4 mm/year respectively).

Análise ambiental da problemática relacionada à falta de água no município de Itu, SP

The water resources scarceness in world become more evident and worried everyday, because the occurrence of water waste, without consider context of potable water deficit, period of long dryness, resource distribution and population density, urban concentration, industrial and rural areas, pollution process, contamination, beyond aspect related to sanitation and public health affect an entire population. At Itu city, this problem is already real, the population face the lack of water risk in dryness period, damaging their life quality and the city economic development, because Itu is a touristic city that has a mixed economy with activities in business dealing, agriculture and industrial department, all conect to water consumption.

Condições mínimas para o encerramento de áreas que abrigaram resíduos sólidos domiciliares

In 2010 Brazil produced about 60.8 million of municipal solid waste, an amount 6.8% higher than in 2009 and six times the rate of urban population growth recorded in the same period. According to a study by the Brazilian Association of Companies of Special Wasteand Public Cleansing (Abrelpe), the average waste generated per person in the same period the country was 378 Kilograms, an amount 5.3% higher to 2009 (359 Kg). The total reached 60.8 milion tons of waste, 6.5 million tons were collected and not end up inrivers, streams and vacant lots. Of this total production, 42.4% or 22.9 million Tons, did not receive proper destination and destiny had dumps and landfills. The data show that the country is in upward trend in waste generation, but did not advance the appropriate destination at the same pace. The waste thus throw open cause public helth problems, such as proliferation of disease vectors (flies, mosquitoes, cockroaches, rats, and others). Generation of odors and especially the pollution of soil, surface water and groundwater through slurry ( liquid black, smelly and high pollution potential produced by the decomposition of organic matter contained in waste), affecting the water. This Study shows the popper closure of the areas, wich long has been degrading our natural resources, not to cause damage to nature and therefore society

As a final result, it was obtained an environmental diagnosis about the situation of each of the four companies studied, and it was possible to know the level of criticality of the impacts in each one, and proposing mitigation measures to control or minimizing them, bringing many benefits to the organization

Degradação ambiental e qualidade de vida na microbacia do Córrego do Gramado – Presidente Prudente/São Paulo

The late industrialization, together with other factors, ended up directing much of the rural population to cities, without adequate planning, resulting in high density and irregular settlements in risk areas to low-income population. The man settled in the urban site to break environmental laws that eventually causing an imbalance in the natural environment, causing or exacerbating the shortage in availability of water resources. This situation also happened in Presidente Prudente, especially in the east, the focus of this research. Therefore, this study aims to understand the causes of degradation of waterways in urban areas, focusing on society's relationship with nature and its consequences on environmental quality and quality of life of urban population located in the watershed of stream of Gramado, Presidente Prudente - São Paulo. In this catchment there is the irregular deposition of solid waste in the valley, remnants of old pollution release of domestic sewage and industrial (currently collected and intended for treatment), accelerated processes of erosion in some areas of intensive use of the relief and consequently, the bed siltation of streams that are part of the basin. The quality of urban life was seen through socioeconomic and environmental indicators, which were identified through questionnaires to residents, according to local residence in the landscape, divided into three segments: the tops 60 residents, 90 residents and 112 residents in the areas in valley bottoms. With these data we can relate them to the degradation of the basin and aggregate them to the quality of life of residents. Field studies were needed to visualize the changes that occurred in the watershed over the past three years, with the implementation of works aimed at improvements to the community as the conduit stream of Gramado and construction and operation of Sewage Pumping Stations...

Impactos e características nos projetos hidrelétricos Sul-americanos: o caso de Inambari no Peru, o investimento brasileiro e a lei de consulta prévia, 2006-2011

Esta pesquisa trata de um grande projeto hidrelétrico, Inambari, que estava se transformando em realidade como parte de acordos entre o governo do Brasil no segúndo período de Lula (2006-2010) e do governo peruano de Alan Garcia – AG (2006-2011). Inambari é um dos mais recentes projetos hidrelétricos peruanos feitos para exportar ao Brasil. Mas, apesar de formar parte de um acordo entre esses países, por agora está detido devido a protestos e mobilizações da população dos territ´porios de Inambari contra a política hegemônica de AG. Analogamente ao caso da estrada Interoceãnica Sul, a construção e operação da Usina Inambari pode ser entendida como um caso emblemático no cenário Latino Americano atual. Esta não seria apenas o maior projeto hidrelétrico da amazônia peruana, custando aproximadamente 4 bilhões de dolares e prometendo um potencial de geração de energia elétrica de cerca de 2.200 MW para exportar ao Brasil por ano, mas também concretizaria o vínculo energético estratégico entre estes dois países através de um complexo de usinas e linhas de transmissão interconectados. Para sua concretização se conta com o amparo financeiro e legislativo dos dois governos e suas instituições de fomento, além de instituições de internacionais de investimento (como o BID e o BM) e do capital internacional (este útlimo proveniente principalmente de empreiteiras brasileiras beneficiárias do modelo de concessões federais). Aqui se estudam os potenciais impactos na economia amazônica do modelo vigente de exploração de recursos naturais hídricos amazônicos através do caso INAMBARI. A conclusão aponta que inexistência de participação popular como o maior entrave ao desenvolvimento amazônico e tenta explicar a novaconfiguração dos movimentos sociais que buscam voz para os povos da Amazônia bem como o pioneirismo peruano em relação a lei de consulta prévia

Caracterização hidroquímica do sistema aquífero Tubarão no município de Americana/SP

The growing interest in the use of groundwater resources is directly related to the economic advantages that the groundwater exploitation offers when compared to surface waters. This happens especially in large urban centers, such as the city of Americana / SP, where the rivers are increasingly contaminated by household and industrial waste. Therefore, this study aimed to characterize the Tubarão Aquifer System, in the city of Americana, to identify and evaluate the spatial distribution of different hydrogeochemical facies as well as understand the rock-fluid interaction through the construction of a conceptual hydrogeochemical model. This study was made based on the recognition of the possible chemical reactions that print the chemical characteristics of groundwater in the area. To do the job, there were two water sampling campaigns of all deep wells used by the City of Americana public water supply. From the results of hydrochemical, classification of water was made by Piper and Stiff diagrams as well as geostatistical data using cluster analysis of principal components. Based on information from the profiles obtained from the survey SIAGAS as well as in geological profiles provided by the city of Americana, we sought to detail the subsurface geology of the Subgroup Itararé in the city of Americana. The results obtained allowed the identification of three hydrochemical types in the study area: Bicarbonated calcium-sodium (1), bicarbonate sodium (2) and sodium chloride (3). The waters have bicarbonate alkaline pH to alkaline and can be considered weakly saline, with electrical conductivity values of around 161 mS / cm. Samples classified as sodium bicarbonate average of 174.99 mS / cm. The pH values ranging from 6.74 to 7.99, averaging 7.52. For the group of waters classified as sodium chloride, conductivity average is 164.32 mS / cm and pH values ranging... (Complete abstract click electronic access below)
