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.

Diagnóstico geoambiental e avaliação de risco à saúde humana para uma área industrial contaminada por hidrocarbonetos localizada no município de Paulínia (SP)

This paper deals with a case study of assessing risk to human health, with the study area of an industrial site in the city of Paulinia (SP) contaminated by oil, which is disturbing situation that occurs in the state of Sao Paulo, which represents risks for human health, as toxic and carcinogenic potential of petroleum products. As an essential foundation for risk assessment, a Geo-environmental diagnosis of the region was made, posing as historical information of the area and accidents, regional geology and hydrogeology, characterization of contaminants and affected media, contaminant transport and data on potential receptors and pathways. Because of the detection of contaminants above the intervention values CETESB (2005) it was possible to proceeded to quantify risks to human health and the determination of maximum acceptable concentrations for no damage to health, using the methodology and software RBCA Tier 2 (ASTM , 1998) and Spreadsheet Risk Assessment recently published by CETESB. The results showed the risk to the health of industrial workers and regular employees of civil works (both on site) for ingestion of groundwater and inhalation of vapors indoors.

Estabelecimento de rotinas de operação e orientações de manutenção para a planta termelétrica do DEN/FEG/UNESP

Steam generation plants have several industrial applications, being important for the national and global energetic matrix. Operational knowledge of steam plants is extremely important to forming a Mechanical Engineer. The facilities from Faculty of Engineering of Guaratingueta have a no operated steam pilot plant, named Thermal Machine Lab. Nowadays, the Energy Department from the faculty cannot explore this lab for its classes, even being essential to consolidate the theoretical concepts with tests simulating industrial applications. The goal of this project was to restore the operational condition of equipment of steam laboratory by fixing the equipment, and creating operational scripts for them. In a close future this lab could be used for classes, research and other applications

Aperfeiçoamento em equipamento para digestão de amostras por via úmida

Aperfeiçoamento em equipamento para digestão de amostras por via úmida. É descrito um aperfeiçoamento em equipamento para digestão de amostras por via úmida que emprega tubos de digestão (20) fechados não encapsulados e aquecimento condutivo que possibilita a rápida decomposição de amostras botânicas, alimentícias, clínicas, ambientais e similares, promovendo um gradiente de temperatura em direção à parte superior do tubo de digestão, permitindo que a temperatura da fase gasosa seja inferior à da fase líquida, de forma que as digestões são realizadas à pressão pouco elevada e, consequentemente, os tubos de digestão utilizados podem ter paredes menos espessas, permitindo o rápido aquecimento e resfriamento das amostras, bem como baixo custo de operação e manutenção, simplicidade, alta frequência analítica,; redução do consumo de reagentes e diminuição da geração de resíduos, dito equipamento provido de um gabinete (10) que evita a contaminação da atmosfera do laboratório por vapores ácidos e a perda dos componentes voláteis da amostra durante o aquecimento
