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. Avaliação da qualidade do ar em ambientes internos: biblioteca pública / Indoor air quality investigation: public library
Over fifteen months, levels of temperature, humidity, noise, light intensity, contamination by carbon dioxide, total suspended particles (TSP) and respirable fractions (PM1, PM2.5, PM7 and PM10) were monitored at the Public Library Amadeu Amaral at São Carlos, SP. Investigation of the ventilation rate and occupancy, concentration of bioaerosols and identifi

3. Potential adverse health effects of wood smoke.
The use of wood stoves has increased greatly in the past decade, causing concern in many communities about the health effects of wood smoke. Wood smoke is known to contain such compounds as carbon monoxide, nitrogen oxides, sulfur oxides, aldehydes, polycyclic aromatic hydrocarbons, and fine respirable particulate matter. All of these have been shown to caus
4. Upper airway response in workers exposed to fuel oil ash: nasal lavage analysis.
OBJECTIVES--Among other constituents, fuel oil ash contains vanadium pentoxide, a known respiratory irritant. Exposure to ambient vanadium pentoxide dust has been shown to produce irritation of the eyes, nose, and throat. The usefulness of nasal lavage in detecting an inflammatory response to exposure to fuel oil ash among 37 boilermakers and utility workers
5. Detection of Airborne Stachybotrys chartarum Macrocyclic Trichothecene Mycotoxins on Particulates Smaller than Conidia
Highly respirable particles (diameter, <1 μm) constitute the majority of particulate matter found in indoor air. It is hypothesized that these particles serve as carriers for toxic compounds, specifically the compounds produced by molds in water-damaged buildings. The presence of airborne Stachybotrys chartarum trichothecene mycotoxins on particles smaller

6. Acute effects of summer air pollution on respiratory function in primary school children in southern England.
BACKGROUND: There is growing concern about health effects of air pollution in the UK. Studies in the USA have reported adverse effects on lung function among children but no comparable studies have been published in the UK. This study investigates the relationship between daily changes in ambient air pollution and short term variations in lung function in a
