Clinical evidence has identified the pulmonary circulation as an important target of air pollution. It was previously demonstrated that in vitro exposure to fine particulate matter (aerodynamic diameter ≤2.5 μm, PM2.5) induces endothelial dysfunction isolated arteries. We aimed investigate effects vivo urban concentrated PM2.5 on rat artery reactivity and mechanisms involved. For this, adult Wistar rats were exposed 2 weeks São Paulo city at accumulated daily dose approximately 600 μg/m3....
Chronic exposure to air pollution has been associated with adverse effects on children's lung growth.We analyzed the of chronic urban levels particulate matter (PM) selected phases mouse development.The occurred in two open-top chambers (filtered and nonfiltered) placed 20 m from a street heavy traffic São Paulo, 24 hours/day for 8 months. There was significant reduction PM(2.5) inside filtered chamber = 2.9 +/- 3.0 microg/m(3), nonfiltered 16.8 8.3 microg/m(3); P 0.001). At this site,...
Many studies have been conducted to evaluate the association between air pollution and adverse health effects using a wide variety of methods assess exposure. However, assessment individual long-term exposure ambient is challenging task has not evaluated in large autopsy study. Our goal was investigate whether urban associated degree lung anthracosis, considering modifying factors such as personal habits, mobility patterns occupational activities. We study Sao Paulo, Brazil from February...
In this study, the effects of aerobic exercise on upper airways and their defense mechanisms were investigated in athletes. The athletes ran two different environments: downtown streets city São Paulo (Street), more polluted, an urban forest (Forest), less polluted. Thirty-eight young healthy for 45 min d−1 randomly during five consecutive days, with interval 48 h before changing environment. Clinical parameters respiratory tract markers evaluated after first run Mondays (1 d) Fridays (5 d)....
The present study is the first assessment of occupational risk associated with artisanal cashew nut roasting using exposure and effect biomarkers, as well a characterization dispersion analysis released particulate matter (PM). A real-time particle monitor was used to quantify PM1.0, PM2.5 PM10. Furthermore, PM sampled Handi-vol sampler, physicochemical characteristics were determined by SEM-EDS analysis. Trajectories, deposition emitted material calculated NOAA-HYSPLIT model. Urinary...
The analysis of chemical elements in the barks trees is an alternative procedure to access spatial heterogeneity traffic related air pollution. However, role tree species characterization variability airborne pollution poorly known. We present observational study conducted São Paulo, Brazil, based on 498 from three common species: Tipuana tipu, Poincianella pluviosa and Ligustrum sp.. considered ANCOVA models compare concentrations Al, Fe, Zn, Cu, Mn, Ba S bark located close streets with...
The characterisation of individual exposure to air pollution in urban scenarios is a challenge environmental epidemiological studies. We investigated if the city's monitoring stations over or underestimate individuals depending on their socioeconomic conditions and daily commuting times.The amount black carbon accumulated lungs 604 deceased who underwent autopsy São Paulo was considered as proxy for PM10. concentrations PM10 residence were estimated by interpolating an ordinary kriging...
Abstract Limited studies have reported on in-vitro analysis of PM 2.5 but as far the authors are aware, bioaccessibility in artificial lysosomal fluid (ALF) has not been linked to urban development models before. The Brazilian cities Manaus (Amazon) and Curitiba (South region) different geographical locations, climates, strategies. drives its industrialization using free trade zone policy adopted a services centered economy driven by sustainability. Therefore, these two were used illustrate...

Particulate matter with an aerodynamic diameter below 2.5 μm (PM2.5), present in polluted air, has been associated a large spectrum of health impairments, mainly because its deep deposition into the lungs. Araraquara City (Southeast Brazil) is surrounded by sugar-cane plantations, which are burned to facilitate harvesting; this process causes environmental pollution due amounts soot that released atmosphere. In work, elemental composition PM2.5 was studied two scenarios, namely harvesting...

Measurements of optical reflectance in passive filters impregnated with indigo carmine may be transformed to ozone concentrations via a calibration curve and constitute low cost alternative for environmental monitoring, mainly estimate human exposition. Given the possibility errors caused by exposition bias, it is common consider sets m exposed during certain period latent on n different occasions. Mixed models occasions as random effects are useful analyze data obtained under such setups....
