Diagnóstico geoambiental e avaliação de risco à saúde humana em terminal de abastecimento no município de Sumaré - SP

The present work deals with the study on the evaluation of the human health risks caused by the leaching of hydrocarbon products from a gas station in Sumaré-SP. First, a geoenvironmental diagnosis had to be done, where information such as: history of the area, chemicals involved, geological characteristics, transport, chemical analysis, were used to make it. The geoenvironmental diagnosis was used in the software RBCA tier 2 which established the risks by all possible pathways. The results indicated that there are risks for groundwater ingestion for commercial (on site and off site) and residential receptors and 10 that there´s risk for inhalation of vapors in enclosed space for the commercial receptor on site. The evaluation also calculated the specific target levels that the area needs to show, in order not to harm human beings and the environment. That makes RBCA a great tool that can helps the remediation actions needed to be done so that the human being and the environment remain secure.

Estudo da qualidade da água distribuída pelo poço artesiano da FEG em relação à água servida pelo abastecimento público de Guaratinguetá

We conducted a study of the quality of water distributed by Artesian Well in relation to water supply served by the public for purposes of human consumption of UNESP Campus Guaratinguetá. Two sections of the network were randomly chosen and monitored for 105 days: the stretch of the pipeline started off the Water Treatment Station of the Autonomous Service of Water, Sewage and waste in the Municipality of Guaratinguetá and ended in a point consumption of the Child Family Center, while the section B began at the output of an artesian well and finished in a point of consumption of the Department of Civil Engineering. It is the deterioration of water quality in parts A and B, through comparative analysis of Bicarbonates, Total Hardness, Total Iron, free residual chlorine, pH, Total Residual, Turbidity, Conductivity, Color, Fecal Coliforms and Total Coliforms. Among the observations that can be highlighted: the Total Hardness was found in highest concentration in the extract; for Total Iron significant variations were obtained for both parts, and reduction of this parameter in two points of consumption analyzed, not the expected increase concentration, because the contact of water along the pipe, the CRL showed significant depletion to section A, which can be related to impurities in the water, the presence of biofilm on the walls of pipes, or because this is the stretch of greater extent to be covered by water for pH, this indicated that the water is alkaline and slightly acidic stretch in section B; Turbidity was found for the higher concentration to the passage, and a considerable reduction of this parameter at point consumption due to deposition of particulate matter along the stretch, the conductivity also showed a higher concentration in the extract, as well as an increase in this parameter at the point of consumption.

Metodologia microbiológica convencional e reação em cadeia pela polimerase (PCR) na detecção de Salmonellasp. a partir de caldos de enriquecimento – Tetrathionato e Rappaport-Vassiliadis

The progressive increase in consumption and production of poultry meat in later years comes forth with an increase of the occurrence of foodborne diseases, including salmonellosis. Salmonellosis is caused by the ingestion of contaminated products, mainly by the consumption of poultry meat which processing and preparation for consumption were not effective to eliminate pathogens. Thus, there is a need for the development of faster more sensitive methods of detection of pathogens as a way to ensure the quality of the food offered to consumers. The goal of this essay was to evaluate the effect of enrichment broths on naturally contaminated poultry meat samples. A total of 65 samples was collected, these samples were rinsed with 370 mL of buffered peptone water (BPS) 1% according with the traditional methodology. All of the samples were enriched with both Tetrathionate (TT) and Rappaport-Vassiliadis (RV) and all were analyzed by the convencional identification method and polimerasis chain reaction (PCR). Of the 65 analized samples, 34 (52%) were positive when analized by the conventional method, while 45 (69%) were positive when analized by the PCR. Amongst the 45 positive PCR samples, 44 samples were positive when enriched with TT, while just 32 samples were positive when enriched by RV. Of the 34 positive conventional samples, 29 samples were positive when enriched by TT and 31 were positive when enriched by RV

Caracterização e origem da composição química da incrustação e simulação de cenários de perda de energia em setor da rede de abastecimento de água da cidade de Rio Claro - SP

The purpose of this work was the inlay’s characterization from the water supply networks of Rio Claro-SP city; as well analyze the influence of network’s aging in the actual system. To do this, some samples of inlays were collected and made chemistry analysis and X-Ray Diffraction Spectrometry. The history of the source water quality was also analyzed, to make possible to known the origins of the inlays. To evaluate the performance of the network, some different scenarios have been simulated, varying the resistance coefficient of the water supply networks of Rio Claro-SP. The characterization results showed that there are basically oxide and hydroxide of iron (magnetite and goethite) and quartz in the inlays, which are materials of high hardness. The hydraulic simulations indicated that the simulated scenarios had a variation of ~2000% in terms of loss of energy

Freqüência do parvovírus suíno em fetos mumificados, abortados e natimortos detectado através da reação em cadeia pela polimerase (PCR)

Porcine parvovirus (PPV) is associated with reproductive failure and it has been found worldwide, including Brazil. Many diagnostic procedures are used for its detection, for example, immunofluorescence, HA, HI and PCR and this is an important technique because it is very specific and sensitive. In this work, the presence of PPV in fetuses from swine farms with reproductive problems was detected by PCR. All of 170 samples from aborted fetuses, mummies or stillborns were sampled by PCR with primers designed to VP2 region of PPV and c-myc (endogenous control). Only 142 samples (83,53%) were positive for c-myc and among them six samples (4,22%) were positive for PPV which were tested in HA. In this test, erythrocytes suspension 1% was used and three samples (50%) agglutinated but they presented low titer (4). For this work, porcine parvovirus was detected in the samples analyzed by PCR and HA. It is important to emphasize the use of endogenous control when material with elevated degree of autolysis is examined

Metodologia Microbiológica Convencional e Reação em Cadeia pela Polimerase (PCR) na detecção de Salmonella spp em carcaças de frango

Salmonella is the etiological agent responsible for one of the most important Food Borne Disease (FBD), Salmonellosis, which generates significant economic consequences in several countries, including Brazil. Poultry meat is one of the most important disseminators of the pathogen. Accordingly, several countries have developed programs trying to reduce the prevalence of Salmonella in poultry meat. Such programs are based on the research of the pathogen in the carcasses, establishing a maximum limit of positive samples at each set of analysis. The Salmonella scans are usually made using the conventional microbiological methods, which tend to be expensive and time consuming. In recent years were developed rapid methods such as polymerase chain reaction (PCR), which can greatly shorten the results time, showing greater sensitivity and specificity than conventional methodology

Avaliação da qualidade da água no sistema de abastecimento da cidade de Santa Lúcia - SP

água que abastece uma cidade se não for tratada pode tornar-se importante veículo de transmissores de doenças. O controle da qualidade é uma medida que visa, principalmente, garantir a saúde da população. O objetivo desta pesquisa foi avaliar a qualidade da água distribuída pelo sistema de abastecimento da cidade de Santa Lúcia – SP. A água proveniente desse sistema chega até as residências e, muitas vezes, é consumida sem nenhum tratamento doméstico complementar. A cidade de Santa Lúcia é abastecida por três poços profundos (P2, P3, e P4). Com o intuito de avaliar a qualidade da água captada desses poços e distribuídas para consumo humano foram coletadas amostras diretamente dos poços e de um ponto de consumo nas áreas abastecidas por cada poço. Foram feitas três coletas em cada ponto, em três diferentes épocas do ano. Realizaram-se análises físico-químicas e bacteriológicas em todas as amostras. As análises bacteriológicas foram feitas para determinação da presença de coliformes totais, E. coli e contagem padrão de bactérias heterotróficas em placa. As análises físico-químicas avaliaram cloro residual livre, fluoreto, turbidez, pH, cor aparente e sólidos totais dissolvidos. Duas amostras foram positivas para coliformes totais, apenas uma amostra coletada no poço 2 foi positiva para E. coli. Para bactérias heterotróficas todas a amostras apresentaram contagem em placa inferior a 500 UFC/mL. Todas as amostras estavam dentro do padrão determinado pela legislação para pH, turbidez e sólidos totais dissolvidos. Todas as amostras coletadas no poço 2 tiveram como resultado ausência de cloro residual livre, o mesmo resultado para os demais pontos na segunda coleta de amostras. Todas as amostras apresentaram fluoreto com valores abaixo do VMP estabelecido pela legislação brasileira porém apenas cinco com concentrações dentro da faixa estabelecida pela legislação do Estado de São Paulo ...
