1. Exposure to particulate matter 2.5 mM collected at high traffic routes in Rio de Janeiro city: evaluation mutagenic, genotoxic and determination of health risks induced by polycyclic aromatic hydrocarbons / Exposição ao material particulado 2,5 m coletado em vias de alto tráfego da cidade do Rio de Janeiro: avaliação mutagênica, genotóxica e determinação de risco à saúde induzido por hidrocarbonetos policíclicos aromáticos
The mutagenicity of airborne particles from combustion is attributed primarily to polycyclic aromatic hydrocarbons (PAHs). We investigated the mutagenic activity of particulate matter (PM2.5) samples collected from three sites in Rio de Janeiro. Samples were collected using a high-volume sampler at Avenida Brasil, the campus of the Rio de Janeiro State Unive

2. Caracterização do material particulado inalavel (MP10) na atmosfera de Paulinia e região
The present work evaluated the particulate matter (PM10) emission contributions of the Replan catalytic cracking plant in the inhalable particulate matter (PM10) of the region affected by the refinery. To separate the contribution of the source under investigation from other sources that contribute to the particulate matter in suspension, the receptor model

3. Análises seqüenciais de agrupamentos aplicadas ao estudo de partículas atmosféricas
The present paper has as objective to apply a sequential Cluster Analysis to the atmospheric particles: Hierarchical Cluster Analysis followed by Nonhierarchical Cluster Analysis. The hierarchical cluster analysis results were used as start point for the nonhierarchical cluster analysis as an agglomerative technique. These particles were taken from two areas

4. A poluição atmosférica por material particulado na mineração a céu aberto. / Atmospheric pollution by particulate matter in the open pit mining.
Atmospheric pollution aspects were analyzed. Two types of ambients were selected for study: a mining ambient and an urban ambient. To obtain a preliminary evaluation of the quality of the air in these ambients a sampling program was accomplished for each area. Two basic points were studied: the concentration of the total suspended particulates and the chemic

5. Novel Multi-Slit Large-Volume Air Sampler
Scientific investigators who are interested in the various facets of airborne transmission of disease in research laboratories and hospitals need a simple, continuous, high-volume sampling device that will recover a high percentage of viable microorganisms from the atmosphere. Such a device must sample a large quantity of air. It should effect direct transfe

6. Simple Liquid Scrubber for Large-Volume Air Sampling
A new large-volume air sampler called the „simple liquid scrubber” is described. It can recover a high percentage of microorganisms from large volumes of air, up to 950 liters/min, and concentrate them into a small volume of liquid at a ratio of about 400,000 to 1. The principle of operation of the scrubber is based on the production of a fine mist in a

7. Comparison of coliphage and bacterial aerosols at a wastewater spray irrigation site.
Microbiological aerosols were measured on a spray irrigation site at Fort Huachuca, Ariz. Indigenous bacteria and tracer bacteriophage were sampled from sprays of chlorinated and unchlorinated secondary-treatment wastewaters during day and night periods. Aerosol dispersal and downwind migration were determined. Bacterial and coliphage f2 aerosols were sample
