1. A incineração de resíduos de serviços de saúde do município de Belo Horizonte/MG e a responsabilidade compartilhada
The Health Care Waste Management (HCW) is a challenge to the institutions involved. An important Brazilian law enforced is the RDC No. 306/2004 ANVISA, which deals with the Technical Regulations for the management of HCW, setting generator as the responsible for managing these wastes from generation to final disposition. A technology of treating this waste w

2. Análise de ecoeficiência de técnicas para tratamento e disposição de resíduos sólidos urbanos / Eco-efficiency analysis of techniques for disposal of urban solid waste
Os resíduos sólidos urbanos são um dos grandes problemas da sociedade atual. Nesse sentido é necessário discutir soluções para o destino dos resíduos gerados diariamente, cada vez mais em maior quantidade, sendo imperativo avançar na busca de alternativas, não só na busca de novas tecnologias e soluções, como também o aprimoramento das metodolo

3. Avaliação do uso de poli(tereftalato de etileno) (PET) como matriz de imobilização de cinzas de incineradores
Industrial hazardous wastes must receive appropriate treatment to ensure a safe disposal to humans and environment. One of the techniques adopted for this purpose is the stabilization/solidification in polymer matrices. This paper evaluated the use of recycled polyethylene terephthalate as an incorporation matrix of incinerator ash. The polymer and the ash w

4. Caracterização das cinzas de incineração de resíduos industriais e de serviços de saúde
Three ash samples from an incinerator in Belo Horizonte (Brazil) were physically and chemically characterized. The chemical composition of the ashes was not always the same, neither in terms of the chemical species nor in terms of the quantities of those that are common to the three ashes. The ashes called CF1 and CF3D contain heavy metals above the detectio

5. Avaliação da ação de rofa e de materiais particulados provenientes da queima de biomassa na resposta imune humoral de camundongos
The ambient pollution is one of the biggest problems of world-wide public health. Several epidemiological studies have demonstrated associations between high levels of particulate matter (MP) and increase of morbidity and mortality. Residual Oil Fly Ash (ROFA) and matter result from biomass burning have been widely used in experimental studies, with the aim

6. A incineração de resíduos sólidos: análise custo benefício do incinerador de resíduos sólidos do P-sul-DF
The object of his preposition is to analyse the benefit and costs of the solid waste incineration. The conceptual frame is about the economy of the welfare, the analyses of benefit cost and the management of the solid waste. The only option of treatment of the special wastes in Distrito Federal is the solid waste incinerator in Ceilândia, and it was one of

7. Environmental impact in the Municipal Landfill Site and Medical Waste Incinerator area in Ribeirao Preto, São Paulo: Evaluation of heavy metals levels. / "Impacto ambiental na área do aterro sanitário e incinerador de resíduos sólidos de Ribeirão Preto, SP: avaliação dos níveis de metais pesados"
Os resíduos sólidos podem conter substâncias químicas com características tóxicas, dentre elas os metais pesados presentes em diversos materiais provenientes de indústrias, funilarias, atividades agrícolas, laboratórios, hospitais e residências. A contaminação por metais pesados apresenta um amplo espectro de toxicidade que inclui efeitos neurot�

8. Modelagem matematica, controle e otimização do processo de incineração em formos rotativos com pos-combustor
The development of a suitable mathematical model, in steady state and dynamic conditions , to carry out optimization and control of the large scale incineration process, stimulated the approach proposed in this work. The development of the mass and energy balances, as well as all the flows of heat, conductive, convective and radiative, were idealized to have

9. Emissão de monoxido de carbono e hidrocarbonetos totais em camaras de incineração - efeito do numero de rotação e composição do combustivel
Thermal incineration has been in use for treatment and disposal of hazardous wastes. The secondary chamber plays an important role in the effective destruction of wastes and control of emission of products of incomplete combustion, with continuous analysis of CO and of unburned hydrocarbons used in real time monitoring of the incinerator pertormance. This wo

10. Modelagem e simulação interativa de colunas de pratos para absorção de gases : um metodo para minimização de poluentes industriais
The objectives of this work are the modeling and the simulation of a plate, multicomponent absorption column, considering the main phenomena taking place in the process and the rigorous thermodynamic of phase equilibria. The problem is considered in the steady-state and adiabatically. A method initially developed for distillation columns is now applied for a

11. Enhanced excretion of thioethers in urine of operators of chemical waste incinerators.
Thioether concentrations were determined in urine samples obtained from ten workers in the despatch department (n = 69), three chemical waste incinerator operators (n = 67), and an analyst (n = 21), all working in the same chemical plant. Urine samples (n = 196) obtained from non-exposed men, including smokers, served as controls. Enhanced excretion of thioe

12. Dioxin concentrations in the blood of workers at municipal waste incinerators.
OBJECTIVES--Increased concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzo-furans (PCDFs) in pooled blood samples from workers at municipal waste incinerators have been reported. This study was undertaken to confirm these results in individual blood samples from potentially exposed and unexposed workers at municipal waste i
