1. FATORES DE EMISSÃO E DE ENRIQUECIMENTO DA CROSTA PARA ELEMENTOS TRAÇO (MP2,5) EMITIDOS PELA FROTA VEICULAR NA REGIÃO METROPOLITANA DE SÃO PAULO, BRASIL
Air pollution can cause several negative impacts on health and the environment. In large urban centers, this pollution is directly related to anthropogenic activities, mainly activities in the transportation sector. This study analyzed data on black carbon, fine particulate material (PM2.5) and its main trace elements from automotive vehicles (S, P, K, V, Cr

3. Variáveis meteorológicas e poluição do ar e sua associação com internações respiratórias em crianças: estudo de caso em São Paulo, Brasil
As transformações no clima urbano das cidades, a excessiva poluição atmosférica e o aumento das desigualdades sociais tornaram-se fatores determinantes do alto risco de internações por doenças respiratórias. Dessa forma, o objetivo deste trabalho foi compreender como os atributos meteorológicos (temperatura do ar, umidade relativa do ar e precipita

4. Avaliação da influência das condições meteorológicas na concentração de material particulado fino (MP2,5) em Belo Horizonte, MG
RESUMO O agravamento da poluição atmosférica nos centros urbanos devido ao crescimento das instalações industriais e da frota veicular é um problema que causa danos ambientais, afetando também a saúde humana, principalmente pela inalação de material particulado fino (MP2,5). O objetivo deste estudo foi avaliar a influência das condições meteorol

5. Effects of exposure to fine particulate matter in elderly hospitalizations due to respiratory diseases in the South of the Brazilian Amazon
Exposure to air pollution is an important cause of hospital admissions due to respiratory diseases. Nevertheless, few studies use pollutant concentration data estimated by mathematical models. A time-series ecological study was developed, using data from hospitalizations due to respiratory diseases in people over 60 years of age, residents of Cuiabá, Brazil

6. Relationship between climatic factors and air quality with tuberculosis in the Federal District, Brazil, 2003-2012
Abstract Introduction: Despite the high rate of tuberculosis indicators in Brazil, the Federal District shows a low prevalence of the disease. Objective: To analyze the relationship between climatic factors and air quality with tuberculosis in the Brazilian Federal District. Methodology: This was an ecological and descriptive study comparing 3927 new case

7. Chemical composition modulates the adverse effects of particles on the mucociliary epithelium
OBJECTIVE:We compared the adverse effects of two types of real ambient particles; i.e., total suspended particles from an electrostatic precipitator of a steel mill and fine air particles from an urban ambient particulate matter of 2.5 µm, on mucociliary clearance.METHOD:Mucociliary function was quantified by mucociliary transport, ciliary beating frequency

8. Relationship between pulmonary function and indoor air pollution from coal combustion among adult residents in an inner-city area of southwest China
Few studies evaluate the amount of particulate matter less than 2.5 mm in diameter (PM2.5) in relation to a change in lung function among adults in a population. The aim of this study was to assess the association of coal as a domestic energy source to pulmonary function in an adult population in inner-city areas of Zunyi city in China where coal use is comm

9. pH in exhaled breath condensate and nasal lavage as a biomarker of air pollution-related inflammation in street traffic-controllers and office-workers
OBJECTIVE: To utilize low-cost and simple methods to assess airway and lung inflammation biomarkers related to air pollution. METHODS: A total of 87 male, non-smoking, healthy subjects working as street traffic-controllers or office-workers were examined to determine carbon monoxide in exhaled breath and to measure the pH in nasal lavage fluid and exhaled

10. Efeito indireto dos aerossóis: observações em nuvens amazônicas em atmosfera poluída e na transição para limpa segundo os dados dos programas LBA/SMOCC/ENFIM! E AERONET/NASA. / Indirect effect of aerosols: observations in the Amazon clouds in polluted air and clean transition to the second program data LBA / SMOCC / AT LAST! And AERONET / NASA.
In the Brazilian Amazon, fires occur seasonally. The pollution generated because changes in time weather and climate of the Amazon. Studies have shown that the emission of particulate matter alters the radiative balance via direct effect (Solar radiation scattering and reflection.) and indirect aerosol (Increased concentration droplet and the cloud content l

11. The effects of air pollution on respiratory health in susceptible populations: a multilevel study in Bucaramanga, Colombia
We conducted a cohort study to investigate the association between exposure to three different levels of outdoor air pollution and incidence of respiratory symptoms in a population with chronic cardiovascular and respiratory disease. We accompanied 756 participants for a period of six months through the maintenance of a daily record of symptoms and clinic vi

12. Lean diesel technology and human health: a case study in six Brazilian metropolitan regions
OBJECTIVE: Due to their toxicity, diesel emissions have been submitted to progressively more restrictive regulations in developed countries. However, in Brazil, the implementation of the Cleaner Diesel Technologies policy (Euro IV standards for vehicles produced in 2009 and low-sulfur diesel with 50 ppm of sulfur) was postponed until 2012 without a comprehen
